ex-conomics | csc

you supported seungcheol through years of being an aspiring athlete, and all you got to show for it was your undergraduate degree and an awkward, stuttered apology when he dumped you to go semi-pro. now he’s back after an injury derailed his career, and there’s only one problem: you’re the only one available to tutor him. you - 0; the universe - 1. talk about no return on investment.

⚽ pairing: choi seungcheol x f. reader ⚽ genre: exes to (lite) enemies to lovers; university au; angst, fluff ⚽ rating: while there is nothing explicit in this fic, there are two brief references to smut. while i can't stop anyone from reading this, i would prefer minors do not interact with this or any of my work. ⚽ warnings: cheol is some degree of famous, reader is a grad student/TA, mentions of an injury and coping with the aftermath of it, lots of economics talk that even i do not understand, swearing, one mention of alcohol, some misplaced jealousy, rom-com tropes, dino is kind of a loser but we love him anyway. probably a lot of other things i missed, but this is actually pretty tame for a fic of this length. ⚽ word count: 13.4k ⚽ thank you: a lot of people looked this over for me in the process and i'm sure i will forget some of them so if i do i'm sorry: @the-boy-meets-evil, @hot-soop, @highvern, and @haologram, who also gave me some wonderful ideas for the vlogs. thank you to MIT for opencourseware existing. i took microeconomics and dropped it, so i couldn't have done this without you. everyone in the discord server for helping me along the way and keeping me motivated. ⚽ author's note: i haven't posted a fic in nearly seven months, so i think it goes without saying that there are parts of this i like and a lot more i'm not 100% happy with. i'd love if this was more fleshed out and 10k longer, but i was able to write anything at all so it's good enough. this was written for the back to school with seventeen collab, hosted by @camandemstudios. thank you both for letting me participate! please make sure to check out the rest of the stories! everyone worked so hard and this collab was a ton of fun to participate in. <3

You look down at the paper. Back up at who handed it to you. Down at the paper again.

“You’ve got to be joking.”

The poor freshman kid laughs, all nerves, and even though the sound is grating, you remember what it’s like to be forced into work study. How far away graduate school seemed; how large your professors loomed over you with all their power and knowledge and credentials; how you constantly felt like the dumbest person in nearly every room you walked into for four straight years.

“Um—”

You sigh, just barely resisting the urge to slam your head onto your desk. “I—it’s fine, don’t worry about it.” Your words do little to ease Freshman’s nerves. He’s still hunched over in the doorway of your office, wringing his hands as he shifts his weight back and forth, in for a lifetime of body pain with the way he’s squaring his shoulders. “You’re sure about this, though? Like, I’m really not being set up?”

“I don’t think so?” he offers, slowly starting to turn green right before your eyes. “Dr. Lee ga-gave me the paperwork himself, I don’t think he would’ve messed it up? Oh no, did I mess it up? Should I go back to Student Services and conf—”

Good god, this kid’s anxiety is gonna stink up your office for weeks. “No need!” you interject. “I’ll just…” Sign it, you want to say, but the longer you stare at the sheet of paper the quicker you’re losing your resolve.

TUTORING REQUEST FORM Student Name: Choi Seungcheol Degree: Undergraduate Major: Business Course: ECON04101 Introduction to Microeconomics Instructor: Lee Yeonseok, PhD. Recommended Tutoring: High (3-4 hours per week)

You curse under your breath. Of the two names on the paper, Dr. Lee’s does not come as a surprise. He’s a notorious hard-ass with an infamous attrition rate—most students don’t last more than a week in any of his classes—but he’s also the sole reason you were able to pay for someof your grad school tuition out of pocket with all the tutoring money you made.

That, however, was two years ago.

“Does he know I don’t tutor anymore?” Stupid question. The kid stares blankly back at you, as if to say I don’t know any more than the people in Student Services, let alone Dr. Lee. It is literally my first year here. “I’m Dr. Ahn’s TA this year. I’ve got my hands full with her bullsh… stuff—”

Immediately, you know you’ve said something wrong, because the kid’s eyes light up, all that previous anxiety disappearing like smoke. “Wait, the same Dr. Ahn that teaches the crypto course?”

“No, that one died,” you say quickly. Kid deflates. “Anyway, I don’t really tutor anymore, especially for econ. As you can see”—you gesture vaguely around the cramped four walls of your office—“they’ve upgraded me. They even put my name on a little placard by the door! Go look! They spelled it wrong! If that doesn’t sum up this university I don’t know what does.”

You heave another sigh. Try to school your face and tone into something that exudes professionalism and finality. “Look, I’m sorry I can’t help you. I tutored Dr. Lee’s students for, like, three years in undergrad so I’m sure they just… forgot that wasn’t my actual job here. Who’s in charge of tutoring these days? I’ll shoot them an email and explain all this.”

Freshman gives you a name, and it takes less than a second to find them in the employee directory. You expect that to be the end of it, but he’s still taking up space in your doorway. You quirk an eyebrow. “Yes?”

The hand-wringing returns, along with an embarrassed flush that disappears beneath the neckline of his school-branded sweatshirt. “I just—um. Maybe you could, uh. Send that now? Before I get back there?”

You blink. “Don’t you have to go all the way back across campus? How slow do you think I type?” He shrugs, and you give up on the idea of getting rid of him. “Fine. What’s your name, anyway?”

“Lee Chan. I’m a sophomore. Do you know that guy?”

“Oh. I thought for sure you were a freshman, but you’re gonna need to be more specific, Lee Chan, Sophomore.”

“The guy they want you to tutor.” You freeze. The guy they want you to tutor is—“Choi Seungcheol,” Chan tacks on, and, yeah, you know—knew, you correct yourself—someone with that name, once upon a time.

But there are a lot of Chois and a lot of Seungcheols. It’s been years since you’ve spoken to the Seungcheol you knew, and that was when he’d broken up with you to—“I heard he’s a football player? Well, used to be, I guess. The girls in the office were freaking out so I guess he’s pretty famous, but I don’t know anything about sports, do you? They said they have photocards of him. I thought they only did that for idols.”

You think about being kids together in Daegu. Think about the exasperated looks you’d share when your parents would drag the two of you to festivals: Palgongsan in the autumn, Biseulsan in the spring; transformation and rebirth. Think about being eight years old and watching your father cram into the small space of the Chois’ living room, standing around the TV with Seungcheol’s dad, shouting at Park Jonghwan. Daegu FC made the FA Cup quarterfinals that year, and you think, of everything, that’s what you’ll remember for the rest of your life.

You think about falling in love slowly. Sixteen and clueless, the pair of you were. Didn’t really know any different, just that you’d look at him and feel butterflies. That you’d hold hands in secret. Text beneath the dinner table. That you’d watch him on the football pitch and be consumed by pride. That the future felt impossibly far away, that life would never catch up to the two of you.

You think about all the football jargon you didn’t understand—the academies, the teams, the implications. You think about, I’m thinking about trying out for the FC Seoul U-18, I just don’t think there’s much more I can do here in Daegu. You think about replying, Oh, I applied to university there.

You remember thinking it must’ve been fate, how easy that had worked out. How easy that first hurdle had been overcome.

You think about how fast everything happened. The try-out, the acceptance, the explosion. Remember being unable to go anywhere those first few months without seeing Seungcheol’s face, touted as the next big thing. Think about applying for scholarships when he was applying for international visas. Think about studying for midterms when Seungcheol was studying English for interviews.

You think about the last few weeks of your relationship, when it felt like you were desperately trying to cling to ghosts. Think about how Seoul had once felt endlessly big, both in opportunity and size, and how it now felt suffocating. You think about, So you’re just giving up? Is that what you’re saying? Think about, I don’t know what else to do. It doesn’t feel fair to you.

You think about all the places you’ve watched him. On countless football pitches; shy glances in school hallways; in the passenger seat, wracked with nerves on the drive to Seoul; poised above you in bed, hairline dotted with sweat as he rolled his hips, telling you how much he loved you.

You think about watching him walk out the door, and how you never watched him again.

So you fire off your email, concise and to the point about why you can’t tutor Choi Seungcheol in Introduction to Microeconomics, and turn to Lee Chan, Sophomore.

“No,” you finally answer. “Never heard of him.”

For all intents and purposes, your rejection should’ve been the end of it.

A few days go by. You hold office hours, attend lectures, work on your thesis when you have both the time and the energy. Try to ignore the feeling of bees beneath your skin, anxiety needling each time you check your email. You were well within your right to decline the tutoring request, but you can’t help but feel like you’ve done something wrong. That someone somehow knows who Seungcheol was to you and will pull you up on it. That those girls who’d gushed about him to Chan are somewhere laughing at your expense.

But you don’t hear anything at all about it… until you do.

Sunday evening. You haven’t moved from your couch in hours, some variety show playing in the background, barely audible over your keyboard clacking. Much to your detriment, you don’t write many papers these days, so you’re out of practice. Feels like you haven’t done anything besides formulas in years, all of your academic knowledge reduced to fucking math, so you’re about ready to toss your laptop out the window long before the email even comes through.

You see, From: Lee Yeonseok. You see, Subject: Choi Seungcheol - Tutoring.

Your stomach plummets to the floor.

You scan the body quickly. You see the words personal favor… friend of his father… urgent matter… and your hands start shaking. Whether it’s from the sheer audacity of this man or anxiety, you aren’t sure, but it’s not like it matters. There aren’t a whole lot of people on campus brave or dumb enough to go up against him twice.

“Motherfucker,” you spit, bitter the only taste in your mouth.

Where did you go wrong to wind up here? You’d followed the script: got the grades, passed the exams, received half of the required education for the Respectable Career, helped a few others along the way chase dreams that may or may not have been their own. You’d fallen in love. Only had a broken heart to show for it, but that’d been in the script, too: The First Love, followed by The First Heartbreak.

The split from Seungcheol was supposed to have been the end of that chapter. You’d planned on never seeing him again, and you never would have, had it been up to you. Apparently the universe has other plans, participation required.

“Did you spill onion dip on the rug again?” You startle, sending your laptop flying. Kaori, your roommate, is perched halfway in between the living room and the kitchen like a cryptid, clearly not expecting your reaction. “Oh. Were you watching porn?”

Face burning, you fetch your laptop from the floor. “In a common area? Kaori, please, I have far more decorum than that.”

She snorts, resuming her trek to the fridge. “See, that’s what I thought, but then I walked out here and you threw your laptop so fast it was like watching my ex get caught watching furry porn all over again.” She pries the lid off a large container of yogurt. “You think this is still good?”

“Dunno. What’s it smell like?”

She sniffs it and pulls it back to check the label. “Vanilla, I think, which is concerning because it’s supposed to be strawberry.”

You shrug. “What’s the worst that can happen, you get extra”—you pause, trying to remember the correct order of things, before giving up entirely—“...biotics?”

“Mm, so close. Care if I just eat this with a spoon?”

Nose scrunched, you wave her off. “Couldn’t pay me to eat yogurt on a good day, let alone if it’s expired. All yours, babe.”

Spoon in hand and a pleased smile on her face, Kaori collapses onto the couch beside you. You try to return your attention to your paper, try to find your momentum again, and it works for all of ten minutes before you’re groaning and slamming the top closed.

You don’t even need to look over to know Kaori’s staring. “What’s up with you?” she asks. Before she can answer: “Wait, is this serious? Because I can’t have a serious conversation in this t-shirt.” You steal a glance sideways. Ask Me About My Hemorrhoid! it says, and you exhale loudly. “Don’t breathe at me, I lost a bet.”

“And continued wearing it?”

She jokingly rolls her eyes. “God forbid a girl has hobbies.” Nudges you with her foot. “C’mon, spill.”

Kaori doesn’t know about you and Seungcheol. Most people don’t, aside from a few old classmates from Daegu who found you on social media and tried befriending you once he started making a name for himself in Seoul. After that, it was just easier to keep things private while you were together. New friends knew you were seeing someone but not their name or how long you’d been together. Any curiosity surrounding why the Choi Seungcheol was following you on Insta had been waved away easily. Our parents are friends, we grew up together. Then you broke up, and there wasn’t any evidence to delete, and he wasn’t following you on Instagram anymore, and it was easier that way.

So, yeah—even though you hadn’t met her until years later, Kaori knows you have an ex. She knows you’ve had a few flings and situationships in the time since, too, and it’s why she’s none the wiser when you ask, “It’s nothing, really. Just—do you follow football at all?”

“Nah, not really. The new guy’s pretty into it and keeps trying to get me to watch the games with him, but it’s so fucking boring? I dunno, I can’t get into it. Not in real life, anyway—I binged all of Captain Tsubasa in an embarrassingly short amount of time, though. Why?”

“Student Services asked me to tutor someone the other day and I had to turn it down. I just don’t have the time, you know? This semester’s already killer, and Dr. Ahn’s been riding my ass nonstop about grades. Turns out it’s some football player, so Dr. Lee emailed me asking me to do it as a personal favor, which means, on top of all the other shit I have to do, I’m now tutoring some football player four hours a week in Microeconomics.”

Her face distorts. “God, that guy’s such a prick. Like wow, you’re good at the economy! Good for you! Who cares! Why don’t you go balance the national debt or something instead of torturing university freshmen!”

You also wrongly assume that’s the last you’ll hear of it from Kaori.

Two days later, after Student Services replies to your email with the days and times you’ll be tutoring Seungcheol, she materializes in the living room to harass you.

“You didn’t tell me your football player was Choi Seungcheol.”

The panic is instant. You know how she means it, but it’s not how your body interprets it. All of a sudden it feels like an interrogation, an accusation, and a whopping serving of guilt takes up residence in the middle of your chest for not being entirely honest.

“Explains this weird text Ken sent me.”

She slides her phone over to you, open to her text thread with her current flavor of the week. Beneath an article about Seungcheol enrolling in classes at your school:

doesn’t ur roomie TA there Why are you calling her “ur roomie” like you don’t know her name?? Rude. Also yes. ask her to get me an autograph No babe pls he was my fav player before he got injured No 🙄 fine. can i come over later? Starting to think you’re using me for my roommate. Get your own job 🙄

You hand her phone back. “I didn’t think you’d know who Choi Seungcheol even is.” It’s the best you can do, even though it just digs you a deeper grave. “You said you’re not into football.”

“I’m not, but unfortunately I am into that stupid man.” She sighs, wistful and longing. “Babe, you have to understand. His dick is so big.”

You hadn’t wanted to stay in Seoul for your graduate degree, let alone the same university you’d gone to for undergrad.

You’d applied to schools all over—Japan, Europe, even a few in the States. Romanticized the hell out of NYU, went window shopping for an overpriced apartment, picked a favorite pizzeria based on nothing but vibes and online reviews. In those few months after graduation, there wasn’t a whole lot tying you to Seoul. Your and Seungcheol’s relationship had been old history by then, your parents split. Your dad stayed in your childhood home and your mother moved a few hours closer to her sister. They’d waited until your brother was old enough to be out of the house.

And it’d just been… a lot. Overwhelming. Some days you could barely shower or feed yourself, let alone move halfway across the world, so you’d stayed in the familiar and tried not to let it feel like failure.

But the good thing about familiarity is you learn its tricks, figure out the hiding spots. Early on, your first or second week of grad school, you laid claim to a study room on a floor of the library everyone else ignored. You write notes on the whiteboard with faded blue markers that are still there days later. The chair on the opposite side of the table is always exactly where you left it, the space between it and the table enough to only accommodate you. Sometimes you leave books—old paperbacks littered with notes in your writing—or papers, just to see if they move.

They never do.

And all of this is why it feels like a punch to the gut when that sanctity is tainted. When you’re halfway through a stack of Dr. Ahn’s exams and the doorknob rattles behind you. When you don’t even need to turn around to know who it is, because he still sounds the same, still has that overwhelming presence. You’ve always sensed him before you felt him.

“There you are,” Dr. Lee says, ambling into the room before you can protest. He, too, is overwhelming, just in different ways. Immaculate posture that anchors his slight frame that’s always dressed impeccably and expensively. Wears a watch that’s triple your tuition. Shoes polished so bright they’re nearly blinding. “I’ve been looking all over for you.”

This time it is an accusation.

Well, you found me, you want to say, but just knowing Seungcheol is behind him, lingering in that half-study room, half-hallway space, is enough to keep you quiet. Like if you speak you’ll summon him closer and you’ll no longer be able to pretend this is nothing more than a nightmare.

You plaster on a polite smile. Say, “Ah, here I am, kyosu-nim,” and put all your energy into trying to glue Seungcheol to the floor with your mind.

Which is fruitless, because Dr. Lee moves further into the room. Gestures for Seungcheol to follow him with an impatient huff, and the study room is small, sure, and with three people it feels cramped, but that’s not the reason it feels like all the air’s been sucked out of the room.

Seungcheol looks… different. He looks as anxious as you feel, and he sticks close to the wall like he’s trying to disappear. Dr. Lee introduces him with grave importance, unaware of your history, and the forced smile he offers you almost looks embarrassed.

You know Dr. Lee is still hammering away, probably giving you a stern talking-to for rejecting his request the first time, but you can’t tear your eyes away from Seungcheol. Feels like the world around you has reduced to a pinhead, all hyperfocus; feels like your lungs are sucking in stale air one at a time.

“...his father is a very good friend of mine, so I expect…”

You expected to feel nothing. Seungcheol had left to chase his dream—one you’d always been so supportive of that it sometimes felt like your dream, too—and, perhaps naively, you thought the distance and the years would’ve been enough. You expected your heart to have hardened. You expected all those nights you spent crying to hit you at full force. You expected anger, hurt—indifference, at the very least.

“...as many hours per week as you both can manage…”

But you should’ve known better. Should’ve expected the butterflies, the way your palms grow clammy, the way your heart rate spikes. Should’ve expected everything to feel upside-down. You should’ve expected to look at Seungcheol and feel sixteen and in love all over again.

“...you are responsible for his academic progress…”

And that simply will not do. You’ve spent the last few years pulling yourself out of that hole, clawing your way back to something resembling normal. You’ve purged the thought of him from your mind—let his scent fade from your sheets, an old sweatshirt he’d left behind; forgot the way his lips felt against every inch of your skin; forgot the way his entire being lit up when he laughed; forgot the safety he encompassed, the way he whispered all those sweet nothings.

You cannot go there again.

So you roll your shoulders back, smile politely. Say, “Ah, kyosu-nim, Choi Seungcheol-ssi seems very intelligent, I’m sure he is capable of being responsible for his own academic standing, don’t you think?”

Dr. Lee cannot disagree without all but calling Seungcheol an idiot, so he hovers before you in shocked silence. Makes a show of huffing and checking his watch, like he’s all of a sudden remembered he’s late for something and being inconvenienced by this conversation he started, and then he’s halfway out of the library with a terse, “Discuss and figure this out amongst yourselves,” thrown over his shoulder.

You have an entire dramatic exit planned in your head. Gather your things, fake a phone call that makes you sound authoritative and important, and brush past Seungcheol wearing your nicest perfume as if all of this is so far beneath you you can’t even bring yourself to care about it.

Of course, you actually have to brush by him for any of that to happen, and since you’ve already decided you will not go there again, you quickly scribble your email address onto a piece of paper and slide it across the table at Seungcheol, who has steadfastly remained planted just outside the door. “Here’s my email. I don’t have time to discuss this right now.” Seungcheol cocks an eyebrow. You start throwing things into your bag haphazardly. You know you look frantic and affected, but there’s not much you can do about that. “What? Send me a copy of your syllabus and what you want to prioritize. It’ll be easier to get through this if we have a plan instead of winging it.”

He seems to catch on to your distaste because he mirrors it. Scoffs as he rolls his eyes and says, “Yeah, no use spending more time together than we have to,” and if you hadn’t gone years without speaking, you would’ve seen right through it.

But you did, so it stings all the same.

As it typically does, the planet keeps spinning after your run-in with Seungcheol.

You grade Dr. Ahn’s coursework. Try running off your anxiety at the gym, even though it’s pretty good at keeping pace with you these days. You meet Kaori’s maybe-boyfriend sneaking out of your apartment early in the morning and he has the good sense not to mention your ex, but you chalk that up to the mess of hickeys covering his neck and not any sense of social decorum.

Other people’s embarrassment saves you a ton of your own, you’ve come to learn.

Throughout all of this, Seungcheol only emails you once to send you his course syllabus. Doesn’t mention tutoring or provide you with his schedule or ask for yours, so when you’re sitting in a bar with your friends, three or four drinks deep and feeling a little petty, you forward him the original tutoring request and make sure to bold, underline, and highlight the “Recommended Tutoring: High” part for good measure.

He doesn’t take your bait—electronically, at least—but he does show up to your office hours the following Tuesday.

Bag tossed onto the floor, he flops unceremoniously into the chair across from you and says, in lieu of a greeting, “They spelled your name wrong. On the door thing.”

“I know,” you reply, your smile polite and terse. Incredible how he has the ability to raise your blood pressure in milliseconds. “What can I help you with?”

“Depends. How long do you have?”

“Well, considering you’ve shown up to my office hours on time, I’m assuming you already know I’m here every Tuesday and Thursday from four to six. So”—you glance at the clock above the door—“assuming no one comes by who needs my help more than you do, you have approximately one hour and fifty-eight minutes.”

Seungcheol is quiet for a moment as he takes you in. His stare is weighted; it makes you feel a little green around the edges. Clinical and sharp, so far removed from the way he used to look at you. You clear your throat. “I looked over your syllabus. The good news is there’s only a midterm and a final and the rest is problem sets. The bad news is there’s only a midterm and a final so they’re weighted quite heavily. You really need to know this stuff inside-out to have any hope of passing.”

“That’s why you’re here, right? Dr. Lee specifically requested you.”

You huff a breath through your nose. “I’m here as supplemental help. I can’t take your exams or do your readings for you. What else are you taking this semester?”

He sighs, sinking further into the chair, very much playing the part of the heir who has no interest in any of this. Which… is unlike him, you think, if you’re even allowed to. The Seungcheol you knew years ago took everything so seriously. Never clipped corners or took shortcuts. Anyone else would think him a spoiled, petulant child. “Business Accounting and International Trade.”

“Could be worse,” you note. “At least those three courses are tangentially related.”

Seungcheol rolls his eyes. “Easy for you to say. I haven’t taken a fucking math class in years.”

You return it. “You remember how to add and subtract, don’t you?”

“I ruptured my ACL, not my…” He trails off, looking a little embarrassed that he can’t name a part of the—“Brain.”

Whatever you were going to quip back with dies on your tongue. It's the first time Seungcheol has broached the topic of his injury—the first you’re hearing of it at all, actually—and he says it like it’s a joke, like it’s not a thing at all, but the pain is all over his face. The bitterness of the situation he’s found himself in. The unfairness of it all.

And there are so many questions you want to ask that aren’t your place: if it’s fixable, if he’ll ever play again, how he’s coping. But you don’t really need to—you can’t imagine how you’d feel if someone suddenly pulled the rug out from under you. If everything contained within the four walls of your office suddenly disappeared.

Not that the man sitting across from you hadn’t already done that, but.

“Right,” you continue, as if he hadn’t said anything at all. You know Seungcheol—know he wouldn’t want you prodding, sticking your fingers in that particular wound. “I want you to take a look at this,” you say, handing over a printout you have saved from your undergrad tutoring days. “Tell me what looks familiar, what doesn’t; what does and doesn’t make sense.”

He looks down at the paper. Back up at you. Down at the paper again. “What the fuck is this?”

“I—what? Cheol, it’s my old notes on recitation. Surely you’ve already covered this—the syllabus says this is week one stuff.” He looks down at the paper again, and it’s so familiar, watching the life drain entirely from someone’s eyes.

You barely resist the urge to slam your face onto your desk a second time.

You meet Seungcheol at the sports center for your next tutoring session.

He likes the humidity and the smell of the chlorine by the pool. He also likes that it’s not the football pitch, so the two of you sit in the bleachers there and go over his lecture notes. Much to your surprise, Seungcheol talks a mile a minute. Has stars in his eyes when he says he finally understands elastic demand curves, supply shock; tells you he spent a whole hour making flashcards.

It’s the first time you’ve seen him so excited since your tutoring began—the first glimmer of hope you’ve felt since Dr. Lee cornered you in your library hideaway. None of this surprises you. Seungcheol has always been smart, even when football was his primary (and sometimes only) focus. He has more determination and grit than anyone you’ve ever met, so you’re not surprised he’s doing well, excelling, but you are surprised—

“Can I ask you something?” Seungcheol shrugs, shoves half a protein bar in his mouth and swallows without chewing. “Why are you… uh. Here?”

“At this university?”

“Not exactly. I mean, I am wondering about that, but I guess… why business?”

Seungcheol hums. Tucks his good knee to his chest and stares down at the pool. No one’s using it, and truthfully the two of you probably aren’t even allowed to be here, but you understand why he likes it. It’s nowhere near as secluded as the library and definitely not as air conditioned, but it is peaceful. Calm. The water laps against the coping in quiet, small waves.

“Ah, I don’t know. You know how it goes.”

You quirk an eyebrow. Never, in all the years you’ve known him, has Seungcheol done anything he didn’t want to do. All that grit and determination. “What about your father, then? Dr. Lee mentioned this was a favor to him. He’s a pretty important person to have in your Rolodex of favors.”

Doesn’t take a rocket scientist to see what this is: Seungcheol’s father has new money; worked from the bottom up, made some smart investment decisions that finally panned out after Seungcheol left for Seoul. Started doing his own thing, made a name for himself. Last you’d heard from your mother, Seungcheol’s brother was second-in-command. Hell, even your own brother did an internship there.

So you know what this is: a father helping his son after his dream was shattered, life turned upside-down. You can’t blame him, even if you’ve heard the whispers from all the way across campus. That Seungcheol is washed up now, trying to nepo his way into his father’s company because of it; that all he knows is sports and he should’ve stuck to that, what does he know about business, why is he the one Dr. Lee went out of his way to help.

Doesn’t stop any of them from smiling at him, though; doesn’t stop them from asking for autographs or selfies.

But you also know this isn’t something Seungcheol seems willing to discuss, so you crack a joke—“I mean, business. God, who’d wanna go into that?”—and go back to what he was willing to talk about.

You’ve never hated elastic demand curves so much in your life.

Deep in the throes of tutoring—when you can’t tell if it’s week two or week twelve—you make it back to your apartment just before ten, head pounding.

The door flies open just as you’re about to punch in the code, and there stands Ken, looking far more put-off than you’ve ever seen him. Looks defeated, if you’re being honest, like someone mopped up all his emotions and wrung them out like dirty dishwater.

“Oh, hi,” you say hesitantly. The man in front of you seems too much like a caged animal to let your guard down. “Everything okay?”

He aborts a nod halfway. Mutters an apology as he brushes by you and stalks down the hall, disappearing around the corner to the elevators. Usually he’s a talker—you haven’t been able to avoid a Seungcheol-related conversation in weeks—so you’re a little stunned. Stand there stupidly for a while, and that’s where Kaori finds you a moment later.

“You gonna stand out here all night, or…?”

“Oh—yeah, right.”

You follow her inside. Toe off your shoes and put them in the rack. Focus on the sound of the kettle whistling instead of the overbearing tension in the room. Drop your bag off in your room, throw on a sweatshirt three sizes too big and a comfy pair of socks. Rummage through the fridge for leftovers, contemplate what mindless show you’ll watch as you eat, and you do not, under any circumstances, ask Kaori what happened.

You don’t have to. You knew what this was going to be the first time Ken spent the night—the way he looked mortified to be meeting you in the shared kitchen at seven a.m., wearing a look that begged you not to tell your roommate he was sneaking out.

I, uh, have an early class, he’d said. You know how it is.

Maybe you should’ve called him on it then. Issued a warning-but-not-really. She’ll get attached if you don’t tell her. She should know it’s different for you, if it is.

But you’d convinced yourself it wasn’t your place. Kaori wouldn’t want you in her business like that, so you stayed quiet, just nodded before watching him slip his shoes on and close the door behind him so quietly you wouldn’t have known he left at all if you hadn’t been looking. Gone, just like a ghost.

So, yeah, you know exactly why your roommate looks haunted.

“I’m a few episodes behind on this if you want to watch with me,” you offer, pointing at the television with the remote. It’s a lie—you’ve never watched this show a day in your life, which Kaori seems to know—but she contemplates it nonetheless. “Also, my mom mailed us some cookies. I think they’re in the fridge.”

“Why are there cookies in the fridge?”

You huff a laugh. “They were outside the door this morning before I left for campus. I don’t know—just saw who the package was from and was like, oh, this must go in the fridge.”

She nods. Grabs the container and joins you on the couch. Sticks her feet beneath your butt and doesn’t mention a thing.

The closest she comes is a few days later. Catches you right before you head out to campus and asks how tutoring is going.

“Not bad, actually.”

Her smile doesn’t reach her eyes when she says, “That’s good. I’m glad things are going well for you two.”

Lee Chan, Sophomore makes his unexpected return at your office hours on an unsuspecting Tuesday.

“Can I help you?”

He doesn’t answer right away, just helps himself to the seat across from you. “Maybe,” comes his cryptic retort. “I was thinking about signing up for that crypto course next semester.”

You narrow your eyes. “No, you weren’t.”

He sighs. Looks a little panicked, like he can’t believe that didn’t work. “You’re right, you’re right. I, um—I wanted to come say thank you.” He pauses. “You know, for that… email you sent.”

You blink. “No, you didn’t.”

Lee Chan, Sophomore cracks immediately. Thunks his head on your desk and lets loose a pained sound. It nearly sounds like he’s wailing when he says, “I’m sorry! They put me up to it!”

What you’re able to piece together is this: Lee Chan, Sophomore has become a bit of a celebrity in the Student Services department ever since he met you, Choi Seungcheol’s tutor. And, like any smart, previously unpopular university student would do, he took advantage of it. Might’ve stretched the truth a little to make it sound like he knew more than he did, so now here he is, angling for information the girls with the photocards may or may not have paid him to get.

“They want to know about his girlfriend.”

“His what?”

What you’re able to piece together is also this: the Photocard Girls are certain Seungcheol is dating someone, based on little more than vibes. You suspect these vibes are their three degrees of separation, considering there was an abnormal amount of Change of Major files formed after his enrollment, but you tell Lee Chan that you don’t know anything and, even if you did, you wouldn’t put his business out there like that.

But some part of you still has this inexplicable urge to protect Seungcheol, so you match their offer with interest and tell him to say there’s nothing to report—not that you didn’t know, not that he couldn’t get anything out of you. Seungcheol isn’t dating anyone.

You don’t know if it’s true, but you figure that if it isn’t, he still deserves privacy.

Which is a notion you have trouble explaining a few hours later, when Seungcheol strolls into your office with a grease-stained paper bag full of cheese coin bread, offering one to you with a proud smile that drops slowly when you just stare in return.

“What’s wrong?”

Your mouth opens, closes, opens again. Nothing comes out, even though it should be simple. Some sophomore kid was just in here angling for information or the Student Services department is taking bets on whether or not you have a girlfriend would both suffice, but you cannot bring yourself to say the words.

What you settle on is, “Sorry, I just… had an interesting meeting before you got here.”

“Oh. Are you okay?”

You sigh. Tilt your head back to stare up at the ceiling. “It was about you, actually.”

Seungcheol chokes, starts stuttering over words you can’t make sense of. Says, “Me? Why? I passed my last exam—I mean, barely, but I still passed. And that wasn’t your fault! I didn’t study enough! I’ve been losing my mind over my International Trade class, that shit sucks—”

“It wasn’t about your grades, Cheol.”

“Oh.” Then, slowly, a lopsided, pleased smile overtakes his face. “Haven’t heard you call me Cheol in a while.”

“Seungcheol,” you correct.

He seems to forget all about the meeting. Tries again to offer you a coin bread before he threatens to eat them all himself, so you acquiesce mostly to shut him up, say you’ll bring the extras to Kaori. For some reason, you tell him about how much she’d loved the cookies your mom sent, and the nostalgia sets him off, gets him talking again, asking if they were the yakgwa she used to make when you two were kids.

They were, but you can’t seem to tell him that, either.

Seungcheol: sorry it’s last minute - running late. can you meet me at my place instead?

Seungcheol shared a location with you

You’re halfway to replying—I don’t think that’s appropriate—before you sigh and delete it. Midterms are only a few days away and you don’t have time to argue over where your tutoring sessions will be, so if Seungcheol wants to meet at his apartment that’s where you’ll meet him.

You read over the midterm notes on the train. Once, twice, and then a hundred more times until they’re nearly memorized, all so you can ignore the voice in the back of your head saying what a bad idea this is. That you have no business being on your way to your ex’s swanky part of town or integrating yourself into his life beyond tutoring at all. You shouldn’t know where he lives. Maybe you shouldn’t even have his phone number or answer his texts.

Not that there’s much you can do about it now, two stops away.

Seungcheol greets you warmly, if not a little rushed. Apologizes for the mess once you step inside, although it’s less “mess” and more “haven’t finished unpacking,” but there’s enough clear space to study at the dining table, so that’s where you set up, determined to keep things professional.

“Sorry again about this,” Seungcheol says, placing a can of cola in front of you as he takes the seat across. “I had to meet with my father and lost track of time, I guess.”

“Oh. How’s he doing?”

Seungcheol sighs, leans further back in the chair as runs a hand through his hair. A light brown, now. “Same as he always was, I guess. Talked about the business, about my brother. Can’t get him to shut up about that stuff most of the time.”

“The business is doing good, though.” You cough, clear your throat. “My, uh. My brother interned there during undergrad. I don’t know if your father told you that.”

You don’t know why you say it, because it’s clear from the brief flicker of pain on Seungcheol’s face that he hadn’t known, that no one had told him. And it hurts you too that they felt the need to keep it a secret, to protect Seungcheol from you even in tangential ways.

“He didn’t,” he admits, “but I’m sure he was happy to see him. He was, uh—he was glad to hear you’re my tutor. Said you were always smarter than all of us boys combined.”

You laugh. Hope it sounds casual instead of strained. “Well, no need to prove him right. Come on,” you say, tossing a study guide in his direction, “let’s get to work.”

Everything is alright for a while—nearly an hour at least. He has the formulas memorized and attributed to the correct equations. He can explain supply and demand, preference and utility, but things start to fall apart around budget constraints and constrained choice.

The formulas get mixed up. He grows frustrated when he doesn’t know the answers to your questions right away. Rolls his eyes and gets a little snappy when you correct him, try to explain things differently in a way he understands. At first he’s able to temper it, collect himself before things truly start spiraling out of control, but the longer the two of you sit there the more it all unravels.

He snaps, you snap back, and you can’t figure out why. You’ve survived this long in Seungcheol’s orbit even though you never thought you’d be around him again, and perhaps it was bound to explode eventually, but…

It’s the familiarity, you realize.

You and Seungcheol aren’t friends, though you’ve been playing at it for weeks now: meeting outside of the library or your office, the personal conversations bordering on reminiscing, being in his personal space. You don’t belong here. You don’t want to be his friend—you can’t be, not for real or pretend.

“That’s not what I’m say—”

“Then explain it better,” Seungcheol fires at you, eyebrows creasing. “You’re the tutor here.”

You roll your eyes. “I’m trying, okay? All I meant was—your answer isn’t wrong, but I know Dr. Lee and he’s going to want more than that in a response.”

“Right—not good enough, like I said.”

“I’m just asking you to expand on your answer—”

“And I’m telling you that’s all I’ve got. I’m not like you, all right? I don’t have all this shit just floating around in my head all the time. I’m not smart, I barely have any idea what’s going on half the time, and you sitting here being condescending about it is doing fuck-all to help.”

You inhale sharply, taken aback at the hostility in his voice. Suggest calling it for the night, say neither of you will be productive if you keep going like this, and neither of you bother to apologize.

So much of your relationship with Seungcheol was marred by clichés.

The two of you passing notes back and forth during class. You in the bleachers of all his games, screaming along to the team chants, waving a sign around with his name on it. Not realizing you had a crush on him at all until he liked someone else and it made your stomach hurt. Childhood friends turned lovers.

Another cliché: that it’s starting to feel like that all over again.

Seungcheol sits across from you in the library, econ textbook cracked in half in front of him as he pays no attention. Keeps grabbing his phone each time it vibrates across the table. Can’t fight the smile that forces its way onto his face when he reads whatever’s there.

Stupid, you think—both to do this and to think it’d play out any other way. Seungcheol left years ago. Probably lived ten lifetimes while he was away while you were here in this exact spot doing this exact thing. Barely lived half a life, just stuck your nose in textbooks and forced your way through.

“Cheol,” you say, trying to drag his attention back to the study guide. No use. He’s typing away, presses his tongue into the fat of his cheek as he responds. “Seungcheol,” you try again.

Also fruitless.

You have no claim here, you remind yourself—not to his time, not to him. He’s only here because someone else mandated it. You’re only here because someone else mandated it, but it stings all the same. Another reminder of what used to be, of what ended regardless of what you wanted. Another reminder that the role you used to play in his life is not the role you play now. That the space you used to take up created a vacancy, and eventually it was going to be filled.

And if this was anyone other than Seungcheol, if you were more emotionally evolved when it came to him, it wouldn’t gnaw at you as much. All of this would roll off your shoulders.

But it isn’t, and you’re not.

“If you’re not going to listen, then—”

“I am listening,” he interjects, but he’s not looking at you. Not looking at his textbook or his study guide. Keeps laughing and smiling at his phone, and it’s sick how bothered you are by it. That it feels like your stomach’s been turned inside-out with jealousy; with annoyance, because you don’t want to be here anyway, don’t want to do this anymore, and you’re wasting your time on someone who doesn’t appreciate it.

Perhaps he never did.

“What are we discussing, then?”

Still not looking up: “Consumer theory.”

You laugh—more a huff of air than anything, grin sardonically out of one corner of your mouth. Seungcheol sees none of it. “Wrong,” you answer, already expecting the way he shrugs it off. “I’m gonna skip ahead a few chapters, though. Consider it a freebie for your business class.”

It must be your tone that finally grabs his attention. Cutting, precise, purposeful. Seungcheol lowers his phone, quirks an eyebrow, wonders where this is going to go. It’s clear he’s pissed you off, that you’re itching for a fight. It’s clear the years of silence are finally coming to a head.

“Let’s talk about ROI. You know what that is?” You barely give him a second. “Return on investment. A performance measure used to evaluate the efficiency of an investment or compare the efficiency of several investments. So, let’s say I make one-hundred-thousand won on a ten-thousand won investment: my ROI is 90%. Are you following?”

He nods.

“Great, now let’s try something a bit more hypothetical.” You suck in a breath. “Let’s say I invest years of my adolescence into someone. A friend at first and then something more. Let’s say I played cheerleader, supported every hope and dream he had—went to every game, cheered him on, helped him practice his English. Held his hand and talked him down when the pressure felt overwhelming, when the only thing that felt inevitable was failure. Now, let’s say all I got in return was a stuttered, awkward apology as he dumped me and walked out the door. Let’s say that guy showed up again after years of silence just to once again waste my fucking time.”

The thing about pain is it’s not linear. What hurt five, ten years ago might not hurt today, but it might tomorrow; what hurt yesterday may never hurt again. The thing about pain is it lets you stick your head in the sand until it can’t anymore, and that’s where you are now: that window of time between Seungcheol walking out the door on the assumption you’d never see him again before he bulldozed his way back into your life has been slammed closed, locked up tight.

So you don’t even notice you’re crying until the room goes deathly silent and you can hear the drip drip drip of tears on paper. Until you watch Seungcheol’s hands flex and unflex in mid-air, stuck in that liminal space, wanting to reach out but knowing he has no right to. Until your chest aches so bad you’re sure you’re either about to break into stardust or cease to exist.

Until you say, “What, Choi Seungcheol, would you say my fucking return on investment was?” and he has nothing to say at all.

Kaori invites you to a party.

Just something small to celebrate the end of midterms and a classmate’s birthday. Nothing out of control or raucous, not even the kind of thing that’d earn a second glance from campus security. I won’t even make fun of you if you leave before eleven, is how she sold it to you, in addition to a small amount of begging and bargaining and a powerful set of puppy-dog eyes.

After everything the two of you have been through, you find it hard to say no.

So here you are, nearly eleven o’clock on a Friday, a cup of cheap beer in hand. A friend of a friend of a friend is wailing into a karaoke machine and although your ears are bleeding, it does feel nice for that to be your greatest worry. You aren’t thinking about your classes or how you’ve been prioritizing everyone else’s academic success. You aren’t thinking about whatever’s going on between Kaori and Ken. You aren’t thinking about Seungcheol.

At least you aren’t, until he walks through the door.

You’re going to continue not thinking about him at all—not about the fact he’s alone or how good he looks in a simple black T-shirt that’s a little taut in the shoulders. You’re not going to think about the way the air shifts, like the universe knows he’s important and is willing to accommodate. You’re not going to think about how Kaori catches your eye across the room, recognizes him from all her internet searches, and the way she mouths oh my god he’s so beefy at you.

You’re not going to think about how guilty you feel that she doesn’t know, because if you do you’re certain it’ll take over.

You watch Seungcheol work the room; watch as he floats between conversations, as strangers fall over themselves at the sight of him. How eager everyone is to give him something and how reluctant he is to take them. You watch as he winds up in the same circle as Kaori and how she must mention you, oh, your tutor is my roommate, because there’s a question in return before he turns and meets your gaze.

You wonder why the distance between you feels more insurmountable now than ever before.

Seungcheol finds you in your office.

It’s not a Tuesday or a Thursday, far later than four to six in the evening, but he doesn’t even bother knocking before he’s barreling in, stifling your space with his bad energy.

You haven’t seen him in nearly two weeks. Not since the party, if that even counts. Hasn’t bothered to reply to any of your texts or emails, and that was just fine by you, if that’s how he wanted to act, but it isn’t until he’s brooding on the other side of your desk that you realize you’re still aggrieved, too. Feels a little too familiar, him leaving you behind and in the dark.

So you don’t mean to—typically have much more professionalism than this—but when he tosses a stapled stack of papers with a barely-passing grade on your desk and says, “This is your fault,” the words come automatically and without forethought.

“Fuck off, Seungcheol.” It’s not your words that take him by surprise; more so the roll of your eyes, the accompanying huff. The impression that all of this is beneath you and nothing more than a mere annoyance. That however affected you were two weeks ago is not how affected you are anymore. “That’s what happens when you blow off your tutoring for two weeks because you’re a coward.”

He laughs, incredulous; unable to help the sound the tumbles out of his mouth. “I’m a—I’m a coward?”

“Yes,” you reply, tone giving away nothing. All he sees is feigned nonchalance despite the hurricane you feel brewing beneath the surface. “This,” you continue, pinching the corner of the paper between your fingertips and disposing of it in the trashcan beneath your desk, “is all on you, but do please let me know if there’s anything else you’d like to blame me for. I’m all ears.”

You don’t miss it: the way Seungcheol’s eyes grow wide at your ‘I’m all.’ The way he thinks you’re going to punctuate that sentence with yours, and it nearly has bile rising in your throat. Makes you want to scream, rip at your hair. If the last few months have taught you anything, it’s that you are still hopelessly in love with the man across from you—the man that continues to leave before he’s left, always at your expense.

So, yeah—Seungcheol is a coward, but only when it comes to you.

But he doesn’t look much like one now, gripping so hard at the edge of your desk that his knuckles have gone white, baseball cap pulled down low enough his eyes are barely visible. He’s always been overwhelming, always carried himself with an exaggerated arrogance even when it wasn’t warranted, always took everything so seriously, and maybe that’s why you’d thought he’d treat you the same way. Take you seriously. Wouldn’t just throw it all away on a maybe thing, and that’s why it's been years and you still aren’t over it.

Maybe Seungcheol is a coward, and maybe so are you.

Because not once since he’s been back have you been able to say what you mean. Can’t seem to tell him about the anger, the hurt, the heartbreak. Played it all off as petty nonchalance because you foolishly thought that would hurt him, that you’ve been reduced to simmering ash, no hope left for a fire.

“I could never blame you for a goddamn thing,” he says, voice so deep you could drown in it.

You so desperately want to know. You don’t want to know anything at all. You want Seungcheol to explain everything to you in detail and spoil the ending, but only if it’s guaranteed to be happy. Enduring another loss like the first time—you’re not sure you can take it. Not after you two have crossed paths like this, because you’ve never quite believed in fate but you think that has to mean something. That so much time and life had transpired and you two came back together.

Today, though, it doesn’t look like you’re going to get any answers.

Seungcheol straightens, looms at full height. Digs into the pocket of his sweatpants and pulls out a thumb drive. Wordlessly, he hands it over, and then he’s gone just as abruptly as he’d arrived.

Again.

Kaori wants to spend the weekend moping, and you can’t come up with a good reason not to join her.

She doesn’t mention Ken once. Not when she’s sobbing over A Silent Voice and Toradora! after that. Not when she keeps glancing at her phone every couple minutes to see if she has any texts. Not when you—only halfway paying attention between grading and your own assignments—suggest ordering something for delivery, maybe that new burger place down the street you heard was good, and Kaori shuts it down so vehemently you can only assume it was Ken’s favorite place.

Kaori just cries over the man with the big dick she never expected to take so seriously, and not even your stonewalling makes her feel ashamed of it.

And there’s respectability in that kind of openness and vulnerability. At least whatever she’s feeling is honest; at least she can admit she’s sad. You think watching Kaori process her breakup might help you process yours too, years too late, so you suck in a breath and ask, “Can I tell you something or is now not a good time?”

Kaori looks over at you. Dabs a soggy tissue at her eyes. “Well, I guess it depends,” is her answer, and she doesn’t shy away from how waterlogged her voice sounds. “If you’re going to tell me you’re a Takasu and Kawashima shipper, maybe, but if it’s anything worse I’m not sure I could take it.”

“I—what? Who even are they?” She gives you a half-hearted thumbs up. You sigh in response, sink further into the couch. “It’s, uh.” Clear your throat. “Do you remember when we met sophomore year? At that party? And I told you I wasn’t looking for anything and you said, and I quote, why not, I have a sixth sense for this kind of thing and I know that guy will have a huge—”

She hides her face behind her hands. “Ew, god, yes I remember that. My dick whisperer era. How embarrassing.”

“Right. And I told you I wasn’t looking for anything because I’d just gotten out of something.”

“Not really by choice, if I remember correctly. I told you if it was quiet it should’ve been loud, and then you never talked about it again.”

You nod. “I—yeah, that sounds like something I would’ve said.” You suck in a deep breath. “Listen, this is probably gonna sound bad considering I did never talk about it again, but—”

“Hey,” Kaori says, nudging you with her foot. Meant to be comforting, somehow. “It’s okay. There’s a lot you don’t know about me, too… most of which I’m not sure you should, actually.”

A laugh forces its way out, gives you a nice reprieve from the anxiety of the conversation you’re about to have. The need to explain it all, the need for advice. Maybe it’s not her—or anyone else’s—business, but you think you’ve kept this to yourself long enough. You and Seungcheol loved each other, once, and it seems foolish that no one knows.

Maybe Kaori had been right. Maybe love should be shouted from the rooftops; exist out in the open. Maybe something hidden in the shadows can never thrive in the light, and you knew it back then, deep down, but now it seems so obvious.

You think back to a few days before the library. Think about how things didn’t feel good but they felt okay. Think about the frustrated crease between Seungcheol’s eyebrows as he stared down at his textbook and how all you’d wanted to do was smooth it. Think about how you’d rolled your lips and tried not to laugh; how you thought it’d take a miracle to help Seungcheol pass this class.

Think about: What is the difference between the short-run and the long-run from the perspective of production theory?

Think about the short-run of your and Seungcheol’s relationship—that you’d burned bright and fast, even though it’d felt like a million years. Hadn’t dared to consider the long-run because anything beyond that bubble felt impossible.

Think about: Which of the following is not a property of isoquants?

Think about the way Seungcheol’s eyes lit up when he knew the answer. That they’re always linear, he said, and you smiled at his enthusiasm, raised your hand to high-five him and dropped it when he hadn’t noticed.

You think about the explanation—isoquants can be linear when inputs are perfectly substitutable—and what those graphs look like. Downward sloping, left to right. Think about how the graphs change when the isoquants are perfect complements.

L-shaped. Less straight as the inputs become poorer substitutes.

You know what your and Seungcheol’s graph would’ve looked like back then.

So it’s easy, almost, to tell Kaori everything. You tell her about growing up in Daegu, about the smell of the azaleas at Biseulsan in the spring. You tell her about how your parents had befriended the neighbors, how they had a kid your age, that that kid was Seungcheol—yes, that Seungcheol.

She’s able to anticipate the rest from there, but you fill in the blanks of what she can’t: being sixteen and falling in love, holding hands, the clandestine notes. All those football matches and how your throat would be hoarse from cheering. How nauseous you’d felt applying to university in Seoul, how excited you were when Seungcheol said he was coming with you. That, after you arrived, it felt like you were living in fast-forward. Barely any time to breathe or adjust; no time to just be you and Seungcheol. You had to be a student, someone responsible; Seungcheol had to be a phenom.

“Could you feel it was going to happen?” Kaori asks, now sat ramrod straight, all her attention on you. “Like, did you know?”

“I don’t know,” you admit. “Maybe I did? It’s hard to say now, all this time later. I know things definitely felt different, like life was pulling us in opposite directions.” You laugh, bitterness coloring the edges. “You couldn’t go two blocks without seeing him on some billboard, and I was just… normal, you know? I wasn’t some rising star athlete like he was, I just went to my classes. How was I supposed to compete with something like that?”

Your roommate hums, leans back into the pillows as she stares up at the ceiling. “I don’t think you were. Maybe that’s why Seungcheol was worried—maybe he felt like you were losing your own identity feeling like you had to keep up.”

You want to push back, argue that you weren’t, that you didn’t, but the truth is that it’s possible. That the shadows created by Seungcheol’s dreams were so massive you wouldn’t be surprised if they unintentionally swallowed you up. “It still wasn’t his choice to make,” you say, voice barely above a whisper.

And Kaori already knows all about your hurt, listened as you explained it all and laid everything bare. So when she says, “Sometimes that’s just how it goes, though, babe,” it doesn’t feel condescending. “We do the best we can with what we’ve got at the time. You can say now it wasn’t Seungcheol’s choice to make, because it’s been almost five years and you’ve made a life for yourself separate from him. But the—god, this is gonna sound so patronizing, I am so sorry—but you guys were so young. No one has it all figured out at that age.”

She snorts, runs a hand through her messy hair. “Shit, I’m nearly halfway to thirty and I still don’t know anything.” Adopts a frown. “What do you want now? Do you want closure? Want to try to fix things and become friends?”

“I don’t know,” you admit, biting at a hangnail. “He actually, um. The other day when he stopped by my office, he left me a USB drive? And before you ask, no I did not already look at it.”

“A USB drive? Who does this guy think he is, James Bond?” A pause. “Are you gonna look at it, though?”

You do.

Not until the silver, midnight light creeps in through your bedroom curtains and you’ve stared at the ceiling long enough; waited long enough for texts that never came, for divine intervention to, well, intervene. It never did—fair enough—so you decide to take fate by the reins. Grab your laptop, instant headache from the screen, stick the drive into the port.

It takes a second for it to load, but when it does: dozens of videos, organized by date. Vlogs, by the look of them—some from before your breakup but the majority of them from after.

You’re not sure what you expected, but it wasn’t this.

You click on the first one: a month and a half before both of you moved to Seoul. A fresh-faced Seungcheol appears on your screen, cheeks still round with adolescence. He’s in his room back in Daegu, can’t get the camera angle right. Nostalgia hits you like a ton of bricks as it pans to the side, to the wall behind his bed, and you see all his old posters. Mostly football players you couldn’t name, some girl group he used to love, a few movies. Just below them are some of the notes you’d written him in school, and they’re all you can focus on as he talks about how excited he is for the move.

The next: a few weeks after you’d started classes. By then, Seungcheol was well into the swing of things with Seoul FC. Already a big fish in a small pond, tryout offers from European teams starting to roll in. You can hear yourself in the background stressing over your first exam, wishing a generational curse upon your calculus professor. In the video, Seungcheol laughs, whispers like he’s telling the camera a secret as he talks about how nervous he is for his future. I don’t know why, he says, but it just feels like everything is about to change.

There’s a long pause between that one and the next. You understand why when you look at the date: three months after your breakup. Your hands hover uselessly above your keyboard. Whatever answers you’ve been looking for the last few years are probably in this video, but you can’t bring yourself to open it. Not right away, at least.

You click on a different one at random. Seungcheol’s somewhere in Europe, judging from the language on the signs behind him. Snow falls quietly—whenever he filmed this, it must’ve been early. No one else is around, and he cracks a joke that it’s a good thing, people would probably think he was crazy if they saw him. He doesn’t tell you where he’s going but he narrates the entire walk: points out a cafe he’s grown to love. The way to get to his practice stadium from where he’s standing. Pauses near a restaurant and laughs ruefully, shakes his head, says, I don’t know why I’m telling you this, but one of my teammates set me up on a blind date here and I got stood up. You’d probably think that was funny.

(You do. It also makes your chest ache.)

One from two years ago: Seungcheol in a hotel room, clearly nervous. He raises his hand to wave at the camera and you can see the corners of his nails bitten raw. Dark circles beneath his eyes; cheekbones more pronounced than you’ve ever seen them. On the screen, Seungcheol sighs, rakes a hand through freshly-bleached hair. Sucks in a deep breath as he says, I’m so nervous. I’m so—so fucking nervous and I don’t. Fuck, I don’t know what to do. I want to call you because you always knew what to say but that’s so fucking selfish. God, we haven’t spoken in years, and it’s my—that’s my fault, I know, so I brought this all on myself. I just want to hear your voice.

Another from a week after that: the color’s returned to his face, and he’s recording from what looks like a penthouse apartment. Sleek, modern; a small white dog napping on the bed beside him. He smiles, looks like he got his teeth fixed, looks like he’s no longer carrying around the weight of the world. Talks endlessly and excitedly about some tournament. Talks so fast you can barely keep up. Talks around words tinged with languages you don’t understand.

Seungcheol wins a championship. Records a drunk vlog from the same night, hair soaked through with god-knows-what—water, champagne, you don’t know. But he looks radiant. Looks like the culmination of two decades of dreaming. He looks happy, free, at peace. He looks like the reason he let you go, why he had to go away.

You scroll to the bottom of the files. Pause at the last video, dated seven months before the term started.

“Hi,” he says, and you can immediately tell everything is all wrong. Seungcheol’s in the dark, face only visible enough to see the tears tracking on his cheeks. “This is going to be the last one of these I make. I don’t know if you, uh—I’m sure you aren’t paying attention to me—my career—anymore, but. I, um. I got hurt. Ruptured my ACL. They’re not sure I’ll…” A sob escapes him. Has you wanting to climb through the screen to hold him, thumb away his tears, tell him everything is going to be okay. “They don’t know if I’ll ever play again.”

Seungcheol no longer looks happy, free, at peace. “Maybe you’ll be happy to hear that,” he continues. “Maybe it’ll help you to know I threw away our relationship for nothing.”

Cut to black.

The sudden silence is deafening. Has you desperately clicking back to the video you’d skipped, the one from just after your breakup. Seungcheol looks the same in that one, too, like the life has been drained out of him.

I don’t know why I’m doing this. It’s not like I’ll ever show these to you now, since I…

I’m sure I owe you an explanation. To be honest, I don’t know what I’m doing, I just—things have been so hard, and I’m still trying to make sense of it all. I feel like my life went from zero to a hundred before I could even blink and now I’m scrambling. I didn’t think it was fair to—to drag you through that. Me being away, moving to an entirely different continent. I have faith we could do it, I just. I don’t know, baby, I don’t…

You deserve to have your own life. Be your own person. I’m so scared that the world will never see you for who you are—so beautiful and intelligent and kind. You don’t deserve to be reduced to my partner. And if you ever see this, I know you’re gonna roll your eyes. Probably call me a mean name because I took the choice away from you, because you think I’m trying to be selfless and heroic, and you’d be right. It’s not fair, and I wish I could tell you I’m sorry.

I wish I could just… pluck out my brain and give it to you, because even if it killed me to do it, at least it makes sense to me. And I don’t—I don’t want you to think I’m not hurting. I’ve been sick to my stomach since I left. I know I’m making a mistake, I know I am, I just—how do I do what I think is right in the long-run when it’s not what I want right now, or ever?

I don’t want to get over you. I don’t want you to get over me, and that’s how you know I’m not acting selflessly, because you should. I want you to always be happy, I just… wish it was with me.

So, I’m going to keep making these. I’m going to take you along for the ride, wherever it takes us, because you should be here but I can only hope you can one day understand why you’re not. I’m so—I’m so sorry, I don’t…

I’m sorry.

I love you.

You fall asleep and dream that you were the one meant to meet him at that restaurant.

The first thing you do is make a call to your mother.

“Could you send another container of yakgwa?”

On the other end of the line, your mother tuts, motherly intuition audibly kicking into overdrive. Is probably wearing that all-knowing, sly grin she always does when you try to be coy and evasive. “What happened to the last container I sent?”

“Ah, you know Kaori loves those. They barely lasted an hour after I told her what was in there.”

She hums an acknowledgement. Sounds like she takes a sip of tea. “I remember someone else being quite fond of those cookies, too.”

“Well, they are the most popular cookies in the country, so.”

After haranguing you into admitting they’re for Seungcheol and not your roommate, your mother promises to send them quickly. A few days at most, which buys you enough time to figure out how you’re going to approach the man in question.

The vlogs have turned your entire world upside-down. Answered questions you hadn’t even known you had. Took all that anger and resentment you’d been holding onto and set it free, and now you’re just left with… a void. Want to mend things, and it makes you wonder if such a thing is even possible, if it’s too late, but you don’t let those thoughts get very far.

Instead, you let them spur you into action. Have you sitting in front of your laptop at your desk, office hours long since over, silence creeping in the more the department empties. The thrum of the airconditioning and the tick-tick-tick of the clock are all the only company you have.

You worry if it’ll show on camera, how out of sorts you feel: sweating from the nerves, dabbing at your hairline; cheeks warm to the touch. But you suck in a breath anyway, steel yourself. Look at your webcam and the daunting red circle…

And start recording.

He hadn’t gotten it at first. Not really.

There’d been a container of yakgwa outside his door with his USB drive taped to the top of it. No note—not that he needed one to know who it was from, but he wasn’t sure what it was. A goodbye? A please fuck off forever and never contact me again?

He’d just taken them inside. Ate too many of the cookies while feeling sorry for himself. Maybe had a glass or two of wine to compound the issue, and never, ever considered contacting you. Didn’t think he could bear it if you never wanted to see him again, but he just…

Well, he was drunk and alone and he missed you, and he’d rewatched all those videos he recorded a million times before when he was like this, so what was a million and one?

It’d been the same as every time before: he smiled at the happy parts, cried at all his old wounds. Wanted to reach through the screen and strangle his past self for including that part about the blind date, because he never wanted to date anyone who wasn’t you, why would he say that, felt mortified at the thought of you watching that—

And then there it was.

All the way at the bottom. A new video. One that hadn’t been recorded by him—

Hi, Cheol, you say, and that’s all it takes to reduce him to a sobbing, yearning mess. I’m not sure what to say here. I don’t really record much—sometimes for lectures when the professors are too busy, but never anything personal like this, but I watched every single one you made for me and I thought I should return the favor.

I wanted to tell you everything I’ve been up to since you left, but it hasn’t been much. I got my degree. Tutored a lot in undergrad—the same thing I’m tutoring you in now, actually. I was good at it and it felt good to have something that was mine, you know? I almost moved for grad school. Thought for a while I was going to wind up in New York, but then my parents divorced and it felt like too much, too scary, so I stayed. Kaori also stayed, so we got an apartment together. It’s not much, definitely not as nice as your place, but it’s good enough.

I don’t think I ever told you, but she was seeing a guy for a bit and he was… obsessed with you, to say the least. Thought you were the coolest person in the world. They aren’t seeing each other anymore. Ended pretty badly, but—speaking of which, maybe steer clear of Student Services for a while, too.

Sometimes it felt like failure that I wound up staying here. That I had scholarships from all these far-away, prestigious places and didn’t take advantage of them. That I gave into my fear. And now… I don’t know. Maybe there’s a reason I stayed behind. Maybe there’s a reason you ended up back here, too.

Whatever happens—I don’t want you to think I still blame you. Kaori says we do the best we can with what we’ve got at the time, and I understand now that’s what you did. Even though it hurt me, you were trying to protect me. I get it now. And I’m sorry you had to go through all of that alone. I can’t imagine how hard it must’ve been to go to all these places you didn’t know. To have to deal with your injury, the loss of a dream.

You said in one of your videos that you just want me to be happy, and that’s all I want for you, too, whatever that looks like.

Here’s my address if you ever want to come by to talk.

I love you, too.

—and then he’d been up and out the door, feeling stone cold sober, running to the front of his building to wait for his ride.

Felt like the drive took hours. Must’ve hit every red light between his apartment and yours. Took the steps two at a time just to get to your door faster.

There’s a man already standing outside your door when he gets there. One that looks shocked to see him, stars in his eyes, and when Seungcheol says, “Oh, you must be Kaori’s ex,” he looks more like he wants the earth to swallow him whole. Embarrassed in front of his idol.

He knocks on your door and gets no response. Knocks again, harder this time, and he has to try really hard to stifle his laughter when your voice yells from the inside, “Fuck off, Kenji, I already told you she’s not here!”

“It’s me,” Seungcheol yells back.

There’s quiet again. Just enough time for it to feel like his heart is going to beat right out of his chest and follow Kaori’s ex down the hall.

Then you’re yanking the door open—slowly, so slowly, like you’re scared it’s not actually him. Your eyes are brimming with tears when they meet his own, and he doesn’t let himself think, just goes on instinct, when he grabs for you, hands on your cheeks, and presses his lips to yours.

Somehow you taste the same.

Somehow you taste like redemption.

You taste like home.

Seungcheol kisses you until the tears slow. Kisses you until the universe realigns, until he could map your mouth in the dark. Kisses you until all you’re all he knows again.

When he pulls away, you’re gripping at his sweatshirt, don’t want to let him go. He presses his forehead to yours, offers up a million more apologies, starts talking nonsense. Says he’s going to drop microeconomics, what the hell does he know, he barely has a passing grade anyway, what does it matter, he’s such an idiot—

And then you say, “You came back,” and nothing else matters.

“I always will.”

(Later on, as you’re trying to steady your breathing, slick with sweat, your thigh thrown over Seungcheol’s hip as he stares down at you, dopey smile on his face, you say, “Choi Seungcheol, don’t you dare drop that class. I have worked my ass off to get you to barely-passing.”)

if you’ve made it this far thank you so much for reading! i am still very new at writing for seventeen, so i hope this was acceptable. i'm now going to throw myself into the warped tour vernon fic and will hopefully not go another 7+ months without posting anything. 😭

i would love to hear your thoughts! <3

Mandarin Companion - This company sells books that are translated and simplified versions of classic novels as well as a few originals for absolute beginners. They are available in both traditional and simplified Chinese. Their levels don't appear to be aligned with any HSK curriculum but even their most advanced books don't have more than 500 individual characters according to them so they're likely mostly for beginners to advanced beginners. New paperbacks seem to usually be $14 but cheaper used copies, digital copies, and audiobooks are also available. The website is in English.

Graded Chinese Readers - Not to be confused with chinese graded reader, this is a website with information on different graded readers by different authors and different companies. The website tells you what the book is about, what level it's for, whether or not it uses traditional or simplified characters, and gives you a link to where you can buy it on amazon. They seem to have links to books all the way from HSK 1 or beginner to HSK 6 or college level. A lot of the books seem to be under $10 but as they're all from different companies your mileage and availability may vary. The website is in English.

Mandarin Bean - A website with free articles about Chinese culture and different short stories. Articles are sorted by HSK level from 1 to 6. The website also lets you switch between traditional or simplified characters and turn the pinyin on or off. It also lets you mouse over characters to get a translation.

Chinese Track - Another podcast aimed at learning Mandarin but this one goes a bit higher into lower intermediate levels.

Dimsum Mandarin - An older podcast archive of 30 episodes of dialogues aimed at beginner to upper beginner learners.

Dashu Mandarin - A podcast run by three Chinese teachers aimed at intermediate learners that discusses culture topics and gives tips for Mandarin learners. There are also male teachers on the podcast which I'm told is relatively rare for Mandarin material aimed at learners and could help if you're struggling to understand more masculine speaking patterns.

Learning Chinese Through Stories - A storytelling podcast mostly aimed at intermediate learners but they do have some episodes aimed at beginner or advanced learners. They have various paid tiers for extra episodes and learning material on their patreon but there's still a large amount of episodes available for free.

xiaoyuzhou fm - An iOS app for native speakers to listen to podcasts. I’m told it has a number of interactive features. If you have an android device you’ll likely have to do some finagling with third party apps to get this one working. As this app is for native speakers, the app is entirely in simplified Chinese.

Apple Podcast directories for Taiwan and China - Podcast pages directed towards users in those countries/regions.

SELF STUDY TEXTBOOKS AND DICTIONARIES

Learning Chinese Characters - This series is sorted by HSK levels and each volume in the series is around $11. Used and digital copies can also be found for cheaper.

HSK Standard Course Textbooks - These are textbooks designed around official Chinese government affiliated HSK tests including all of the simplified characters, grammar, vocab, and cultural knowledge necessary to pass each test. There are six books in total and the books prices range wildly depending on the level and the seller, going for as cheap as $14 to as expensive as $60 though as these are pretty common textbooks, used copies and cheaper online shops can be found with a little digging. The one I have linked to here is the HSK 1 textbook. Some textbook sellers will also bundle them with a workbook, some will not.

Chinese Made Easy for Kids - Although this series is aimed at children, I'm told that it's also very useful for adult beginners. There's a large number of textbooks and workbooks at various levels. The site I linked to is aimed at people placing orders in Hong Kong but the individual pages also have links to various other websites you can buy them from in other countries. The books range from $20-$35 but I include them because some of them are cheaper and they seem really easy to find used copies of.

Reading and Writing Chinese - This book contains guides on all 2300 characters in the HSK texts as of 2013. Although it is slightly outdated, it's still useful for self study and is usually less than $20 new. Used copies are also easy to find.

Basic Chinese by Mcgraw Hill - This book also fuctions as a workbook so good quality used copies can be difficult to find. The book is usually $20 but it also often goes on sale on Amazon and they also sell a cheaper digital copy.

Chinese Grammar: A beginner's guide to basic structures - This book goes over beginner level grammar concepts and can usually be found for less than $20 in print or as low as $2 for a digital copy.

Collins Mandarin Chinese Visual Dictionary - A bilingual English/Mandarin visual dictionary that comes with a link to online audio files. A new copy goes for about $14 but used and digital versions are available.

Merriam-Webster's Chinese to English Dictionary - In general Merriam Websters usually has the cheapest decent quality multilingual dictionaries out there, including for Mandarin Chinese. New editions usually go for around $8 each while older editions are usually even cheaper.

(at the end of the list here I will say I had a difficult time finding tv series specifically made for learners of Mandarin Chinese so if you know of any that are made for teenage or adult learners or are kids shows that would be interesting to adults and are free to watch without a subscription please let me know and I will add them to the list. There's a lot of Mandarin language TV that's easy to find but what I'm specifically interested in for these lists are free to watch series made for learners and/or easy to understand kids shows originally made in the target language that are free and easy to access worldwide)

hi, do you have any resource recommendations for laypeople who want to grasp the most important essentials/fundamentals of material science? any help will be very appreciated!

Great question! Unfortunately, our definitions of 'laypeople' and 'fundamentals' may vary, so if this list doesn't have what you're looking for just let me know and I'll give it another shot.

Let's start with some... let's say 'unpublished/unofficial' resources. First - this blog. Not to toot my own horn, but I've got a good collection of original posts (try the tag MyMSEPost, or this year's newest variety 2024Daily) that I hope are fairly readable to the general public - and come with links and further reading resources for each topic. However, these posts are not comprehensive. I don't think I've ever talked about what is a crystal structure, for example. [Also, I've been doing this for, wow, almost 10 years now, so... that's a fair number of posts...] I also, one upon a time, made some MSE Masterpost posts, though those are probably pretty outdated by now and I can't guarantee the links all work.

Another resource is msestudent.com. They don't have an about page, but it seems to be a more official (i.e., non-Tumblr) blog about the fundamentals. That being said, while they do have a search system, they don't seem to have a table of contents. Both of these resources will help you learn some fundamentals, but they won't tell you what the fundamentals are if you don't already know them.

Other science Tumblr blogs have come and gone over the years, but @materiallugy seems to be currently posting, and @matmake was not too long ago. Both have separate websites with resources, though I'm not sure how comprehensive.

Now for undergraduate level resources that are comprehensive. These are introductory, but I suppose they might presuppose a high-school level education (basic chemistry and physics, probably):

Online classes, such as MIT OpenCourseware, or Coursera (two examples of many). Some of these kinds of resources are free, some aren't. MIT, in particular, isn't so much a class you take online as it is the resources (and sometimes videos) of their classes.

Textbooks. I used Materials Science and Engineering: An Introduction (Callister and Rethwisch), which I think is pretty common and a well respected book. Obviously it costs money, but I think it's safe to say you could go back a couple editions and save some money.

Less comprehensive but still official is the University of Cambridge's Teaching and Learning Packages. Again, this won't tell you what are the fundamentals if you don't know already know. For example, there are 78 at the moment - I wouldn't say the additive manufacturing TLP is essential to MSE, but atomic scale structure of materials is.

Additional resources:

Specifically corrosion

Online, virtual, general chemistry textbook

Online, virtual, organic chemistry textbook

Someone else's compiled list of links and resources, which may be outdated

YouTube videos from a professor of MSE (side note: I have not watched these and cannot verify their accuracy or usefulness, but the guy does teach this stuff for a living...)

Hope this helps, and everyone feel free to chime in if you have any resources of your own you use!

[megumi-fm]

Hey Meg! I was just catching up on your posts and wow, congrats on publishing the paper! I'm so excited for you and how far you'll go (it's so cool that you're working with alpha fold!!)! 🥳 How did you learn bioinformatics? Are there any resources you'd recommend for a complete beginner? (I'm trying to learn how to do proteomics analyses rn, but I can't seem to find many resources I can easily understand 🙈)

hii!! thank you so much for the wishes! the paper was a part of my final project with my team + guide so it was really a group effort <3 my teammates and I are all first authors, they were just kind enough to put my name first xD and yes! my current alphafold work is a lot of fun ^=^ I'm really enjoying my internship hehe

okay so I learnt bioinformatics as a part of my uni curriculum, and we mainly relied on these two textbooks

Essential Bioinformatics by Jin Xiong

Bioinformatics: Sequence and Genome Analysis

In addition to this, I also recently found this textbook titled Bioinformatics: An Introductory Textbook by Thomas Dandekar, Meik Kunz which focuses both on basic bioinformatics concepts and how to use the available tools. I especially like this book because I found it super easy to understand

EMBL also offers courses! even for synchronous online/in person courses that have ended, they tend to upload course materials. There's one for proteomics analyses as well- I've checked out the mass spectrometry videos under this course and they start with the very basics

In addition to these, here are some playlists on youtube that've helped:

Foundations of Systems and Computational Biology, MIT OpenCourseWare // classroom videos, I'd suggest to check specific videos for a topic of your choice rather than actually going through all of them

Computational Systems Biology, IITM // videos on the basics of systems biology, networks and modelling

Bioinformatics 101 // videos on how to use a lot of tools, however this primarily focuses on gene expression and RNA seq data

lastly, I don't know if this would be particularly helpful given what you're looking for, but this textbook on Computational Genomics with R is a blessing for Omics related Data Analysis. So if you ever need to use R in a biological context, this would be a great place to start

yeah! so these are the majority of the resources that I've used, I hope they help! Just a heads up that the links to the textbooks I mentioned in the beginning are direct download links and won't take you to any website.

If there's anything else I can help with, feel free to reach out ^=^ best of luck!

Você está numa jornada rara e poderosa: buscar conhecimento real, não distração. Isso exige coragem, paciência e direção. Aqui está um caminho para você escapar do "pão e circo" e dominar temas fora da curva, que te deem vantagem real no mundo:

---

1. Assuma o papel de observador

Comece a observar o mundo como se fosse um jogo. Pergunte:

Quem está ganhando?

O que eles sabem que os outros não sabem?

Onde está o foco da atenção pública… e o que está sendo escondido?

---

2. Estude os temas que os "donos do mundo" estudam

Esses assuntos raramente aparecem na TV:

Tecnologias emergentes: IA, computação quântica, blockchain, biotecnologia, energia limpa avançada.

Psicologia de massa e engenharia social: como governos e corporações influenciam comportamentos.

Geopolítica real: entender como funcionam as elites globais, como o Fórum de Davos ou grupos como o Bilderberg.

Filosofia profunda: estoicismo, hermetismo, taoísmo, Caibalion, Gurdjieff.

Finanças descentralizadas (DeFi) e criptomoedas: onde está o novo ouro.

---

3. Aprenda onde ninguém está olhando

Fóruns como LessWrong, The Saylor Academy, MIT OpenCourseWare.

Podcasts como: Lex Fridman Podcast, The Portal (Eric Weinstein), Naval Ravikant.

Plataformas de cursos avançados: Coursera, edX, Khan Academy, Udemy Pro.

Canais e autores que estudam inteligência estratégica, como Robert Greene, Yuval Harari, Ray Dalio, Balaji Srinivasan.

---

4. Construa um mapa de conhecimento

Você quer dominar. Então vá além de “aprender” e comece a organizar, aplicar e transformar conhecimento em resultado. Use este ciclo:

1. Descobrir (curiosidade)

2. Estudar (estrutura)

3. Aplicar (experiência real)

4. Monetizar (produto, serviço ou insight)

---

5. Finja ser bobo, mas seja um estrategista silencioso

Essa é uma das chaves dos sábios antigos. Enquanto todos falam, você observa. Enquanto eles gastam, você investe. Enquanto seguem o fluxo, você constrói algo real.

王立協会 - Wikipedia

王立協会（英語: Royal Society）

1660年にロンドンで作られた民間の科学に関する団体[1]である 「自然についての知識を改善するためのロンドン王立学会」 （The Royal Society of London for Improving Natural Knowledge） のこと 結成以来現在まで存続している学会のなかで最古の学会[6]。

1645年頃、イングランド内戦の影響によりオックスフォード大学から研究の場をロンドンに移し、実験哲学に関する活動を始めた数学者ジョン・ウォリスら10名程度の討論グループが王立協会の起源となった[10]。 正式名称は "The President, Council, and Fellows of the Royal Society of London for Improving Natural Knowledge" （自然知識を促進するためのロンドン王立協会） である[10]）。 ロイヤルという名前は1662年にチャールズ2世の勅許を得て法人格を得たためつけられたが、国王または女王はあくまで守護者（パトロン）の位置づけで、フランスの王立パリ科学アカデミーと違って国庫の補助はなく、1850年に政府の補助金を得るまで会員の会費によって運営されていた[1]。王族フェロー、名誉フェロー、外国人フェロー（日本人を含む）を含めて2016年の時点で約1600人のフェローがおり、会員は「王立協会フェロー」を名乗ることが許可される。 この会は当初から国立（王立）ではなく民間科学団体ではあるが、イギリスの事実上の学士院（アカデミー）としてイギリスにおける科学者の団体の頂点にあたる。1783年創立のエディンバラ王立協会（英語版）[注 2]とは関係が薄い。

If you're good at math:

1. Concept Integration:

Find sums which require in-depth knowledge of more than one mathematical concept to solve. A simple example would be using algebraic expressions as sides of a right angled triangle and finding hypotenuse using Pythagoras theorem and then finding the square root of the polynomial by factorization.

2. Proofs:

Practice writing and understanding mathematical proofs. This helps you develop logical reasoning skills and a deeper understanding of the foundational principles behind mathematical concepts. Very Very important even if it is excluded in the syllabus.

3. Explore Multiple Methods: A continuation of the previous tip; when you learn derivations, you can find short-cuts that work out for you. Or you can explore other methods of solving like graphing two simultaneous linear equations to solve, etc

4. Marry a whiteboard: Seriously, it's so much fun to solve questions on whiteboard. Also, Feynman technique (it's basic so not preaching)

5. Give Olympiads:

  Don’t shy away from tackling advanced topics or materials beyond your current coursework. Give Olympiads. They broaden your thinking capacity, and they're reallyyyyyy fun to prepapre for ✨

6. Develop Intuition:

 Work on developing mathematical intuition. This involves recognizing patterns, making educated guesses, and estimating solutions before rigorously solving problems. Cannot stress enough on this point. I got a guess correct. It was fill in the integer type questions and the probability of getting an answer right if picked at random was 1/100. Still, went with my gut instict and got it correct.

7. Use Online Resources:

Platforms like Khan Academy, MIT OpenCourseWare, and Coursera offer advanced math courses and lectures that can supplement your learning.

8. Follow me: most important tip 😉😁

i talked to my therapist today. it was very helpful.

talking to her kind of felt like i was given permission to look into going back to school again.

so among a bunch of stuff we talked about, i told her about my struggles with creating and maintaining a structure and my need to keep my brain actively engaged in something. and i know that i work best in the sort of structure school/college/university classes give, and i told her i want to take my time as im unemployed to learn new things and hopefully make my résumé more appealing by adding new skills. so she told me to look into them, find costs, and do the analysis.

so after finding and applying to a bunch of jobs, going to the mall with joel, and grabbing some hot chocolate from starbucks, i spent a good while looking for educational programs with and without costs. MIT has their opencourseware which is MIT classes but just with everything posted for free online. harvard has online classes that you can take and then pay about $220 for a certificate saying you completed the course (which is damn good if it can lead to a degree). mcc has certificate programs and other schools in the area do adult education. i'm still looking because there's a lot to learn. but i've done so well on being on top of my payments and stuff that i could potentially just get a part time job and be in school again. which i would love. but it's not necessarily feasible, hence the analysis of things im collecting.

after looking into stuff, joel came in and asked me what i was up to, so i told him. i told him i was looking for courses on programming, specifically python, because i'd started learning it during my program at UNH in durham, which i did not do great during. i just didn't understand how to use it at the time.

but joel laid down beside me and talked me through how to write code in python by using d&d as an example. he told me about functions and defining them, and he told me about how to use variables, and he told me about orders and stuff. it was more enlightening than an entire semester at a university because joel sat and explained it all for so long. i'm confident if i were any other person i'd have been clobbered a long time ago, but joel is so patient with me and im so happy that he is.

and then we headed out with the idiot squad for dinner at buffalo wild wings. i got orange chicken boneless wings which were hotter than i expected , making me uncomfortable after like 8, and im CONFIDENT they gave me more than the 15 i ordered. but they gave me a bunch of carrots and ranch and i was happier than a clam at high tide, i was just tickled peach. so good. i did the happy rocking and wiggling thing. just so happy with my carrots.

after dinner, joel and i came back and i grabbed some stuff from downstairs and headed back home. i'm getting breakfast in the morning with the eggs so i wanted to be here the evening before.

i also got to talk to leo a little bit. he's been having a rough time lately, so i was happy to listen to him. man's struggling, but im here for him.

and now it's time for sleeping.

Back on track! Car issues resolved, degree picked, opencourseware selected :) I'm excited. I've been studying for a few days to get myself back in the loop of things.

Will be posting notes and the like here!
