“Again, I’m really sorry about this, Law,” she calls from the other side.
“Don’t sweat it. You’re here now, might as well stay. Shachi will be home in a couple of hours.”
“I’ll make it up to you somehow,” she says, sticking her head out from behind the door, shooting him a bright smile.
Law nods curtly and locks himself in the bathroom, trying not to think about the fact that he’s totally attracted to Penguin’s new girlfriend.
Law is finally home. He kicks off his shoes, hangs his key on the wall and sighs out. Shachi is still at work. Penguin’s on a work-trip.
Peace and quiet.
Under his arm is the World Economic Journal, which he is looking forward to skimming through impatiently before skipping straight to the newest strips of Sora. Then he’ll make a cup of coffee and read the whole paper through in the comfort of his favourite chair by the window. For dinner he’s gonna make shakshouka over rice and then afterwards he’ll maybe open the bottle of wine he’s been meaning to try.
But first he needs a shower. Desperately.
He opens the door to the bathroom and is met with the sight of a strange girl looking back at him. She’s standing hunched over the sink, face drenched with water and she looks shockingly ravishing. Flushed cheeks, wet lips, eyes slightly red. Law has to take a step back.
“Who the fuck are you?” he asks, and it doesn’t carry even a hint of the irritation he was going for. She blinks, looking back at him.
“I’m Y/N,” she says, as if that would explain everything. “Didn’t Penguin tell you?”
“Tell me what?”
“Oh my god, I am so sorry. He said he would tell you. I’m Penguin’s-”
“Aha,” Law interrupts, as it hits him. Penguin’s new girlfriend. “He did tell me about you.”
The girl lets out a sigh of relief. She grabs a towel and dries off her face. Wow, she’s pretty. Good for Penguin.
“Sorry if I frightened you,” she laughs weakly.
“No worries. Where is he?”
“You just missed him. He left for the airport just now,” she says.
And you’re still here? Law thinks to himself, but knows it would be rude to say it.
“Pen has a tendency to promise things on behalf of others, I hope he didn’t force your hand. You’re a lifesaver who’s letting me stay.”
“Stay?” Law sputters. “For how long?”
“Oh, no. He didn’t tell you,” she laments. “He promised me it would be fine. I didn’t even believe him at first, knowing how he is, but he insisted! There’s mould in my apartment. I was supposed to stay here for a week.”
A week. A week? Law sees white. What on earth was Penguin thinking when he promised her this?
“I'll find somewhere else!” she says quickly. “It’s no problem.”
“Don’t be ridiculous,” Law mutters. She looks like a student, there won’t be anywhere affordably decent on that short of a notice. “If he promised you, then he should keep his promise. I’ll give him hell when he gets back.”
“Thank you so much,” she says with a grateful smile. “So you’re Shachi?”
“I’m Law.”
Her eyes go big.
“You’re Law?” she says in disbelief. “Trafalgar Law.”
“In the flesh,” Law says without a trace of humour.
"Oh my god, I've heard so much about you!" she says excitedly. “Pen said you’d be out of town this week.”
“That’s next week,” Law says.
“That fucking doofus,” she moans, and it makes Law frown.
Penguin absolutely acts like an idiot most of the time, but hearing his totally new girlfriend say it so candidly feels wrong. Penguin had been very excited when he told Law about her.
She walks past him out of the bathroom and into Penguin's room.
“Again, I’m really sorry about this, Law,” she calls from the other side.
“Don’t sweat it. You’re here now, might as well stay. Shachi will be home in a couple of hours.”
“I’ll make it up to you somehow,” she says, sticking her head out from behind the door, shooting him a bright smile.
Law nods curtly and locks himself in the bathroom, trying not to think about the fact that he’s totally attracted to Penguin’s new girlfriend.
----
All his plans for the night get flushed down the drain. There’s no point in even attempting to uphold his priorly planned out schedule. He no longer feels at ease in the living room, not in the kitchen either. He throws together dinner in a haste and eats at his desk.
Sometime as he’s hidden away in his room, Shachi comes home. Law can hear him and Y/N getting acquainted in the kitchen and Law briefly wonders if he’ll be able to grab a hold of Shachi when he walks past and ask if Penguin told him about this, but Shachi doesn’t leave the kitchen. Law can hear increasing laughter, voices talking louder and the occasional opening of cans of beer.
It annoys him greatly that Y/N and Shachi are getting along, putting him in the minority, but he can’t stay in his room all night either. That would be letting them win. He takes his finished plate and brings it to the kitchen.
“Captain!” Shachi exclaims. “Didn’t know you were home. You’ve met Y/N?”
Law finds that a simple nod suffices.
"We're going out tonight."
“Join us!” Y/N exclaims. Her lips are painted red and she’s smiling wide, showing a lot of teeth, some of them unusually pointy. Law has always liked the feeling of sharp teeth. He likes the stain of red lipstick too. He likes-
“I have work,” he mumbles, putting away his final plate and walking out of the kitchen.
“Really?” Shachi asks from behind him.
“Stuff to read, things to write… you know,” Law lies. He turns around and stops in the doorway, attempting to look apologetic.
“Come on, I bought your favourite,” Shachi says, opening the fridge to show a six pack of Law’s go-to beer. If he wasn’t tempted to stay before, he definitely is now, but Law prides himself on his impeccable self control. It’s going to take more to tantalise him.
“Another time.”
The evening flies by in passiveness. Law continues to hide in his room. The wine stays unopened. Sora remains unread. The World Economic Journal lies untouched.
Shachi and Y/N seem to be having a blast in the kitchen together. They play music and sing along, laugh and talk loudly. The hope of getting just a slice of the evening he had planned out gets bleaker by the hour and when they finally leave, going out to a club or bar, Law’s too tired to do anything else other than lie bed and think.
Think about Y/N.
It's just a little strange, that's all.
Penguin has never had a real girlfriend before. There was never more than one night stands and an occasional fuck friend and Law had never felt attraction to any of them. It’s an established fact that their taste is very different. They sometimes even joke about it when they’re out drinking. Shachi’s into men, Penguin’s into shy girls with sweet smiles and Law likes the ones that bite a little. The three had lived in perfect symbiosis.
Penguin always goes for girls with low self-esteem. Quiet, sweet, kinda needy. Law never gets to know any of them because Penguin very quickly loses interest and then Law never sees them again. Never has Penguin introduced anyone as his girlfriend before.
Y/N is confident, harder and freer than any of his prior flings, although maybe a bit too harsh on Penguin. In a way she reminds him of Shachi, but no one else is allowed to treat Penguin the way Shachi does, that’s reserved for only him. And on occasion Law. Y/N seems like someone that barges in and takes charge, not only feeling at home, but acting like it too. Unabashed and shameless. She absolutely reminds Law of Shachi.
Shachi and Penguin have been attached to the hip since they met at orientation. It’s no secret that Penguin himself has issues with confidence and that’s reflected in his choice in sexual partners, but when it comes to deeper relations it would make sense for him to fall for someone more like his best friend. Someone who completes him.
It’s a pity that Law isn’t attracted to Shachi. He’s a great guy and although Law doesn’t actually think that he’s Shachi’s type, he could picture them together in a vague distant reality. Well, maybe not Shachi himself, but someone like him. Someone like Y/N.
Law shakes the thought away. He’s got to stop thinking. It’s 3 am already and he’s yet to get even a half hour of sleep.
----
“I just wish he told me that she was coming,” Law hisses at Shachi. He takes a large gulp of his lukewarm coffee.
“Give it a break. He thought you were going away this week,” Shachi argues. “Honestly I did too.”
“For fuck’s sake, that’s why we have a calendar! So there could be at least an inch of predictability in this fucking apartment. See, I wrote it down months ago,” Law says, pointing at the calendar on the fridge. Shachi raises an eyebrow at him. Law looks at it himself. The blood drains from his face. He’s written down the wrong dates. How did he-
“You were saying?” Shachi says, clearly amused.
“Fuck off, I don’t know how I…,” Law mutters. “I must have- No. They changed the date. That’s it! They changed it and I-”
“And you forgot to change it in the calendar. Well, there you have it. And that’s-”
“But I-,” Law protests.
“-not Penguin’s fault,” Shachi says with a smirk.
“I can’t believe it. What has become of me?”
“Fucking drama queen,” Shachi laughs.
Law has his little frustrated outburst and then he sighs deeply.
“He should have told me even so. Doesn’t matter that he thought I was gonna be gone,” Law says sourly. Shachi hums in agreement.
“He told me like three days ago, I think it was a last minute emergency,” he says with a shrug.
“She’s not what I pictured,” Law admits.
“No, yeah, I get it. They’re different,” Shachi says. “She’s actually cool though, I think the two of you would get along. You should take this chance to get to know her, Lord knows Penguin’s not gonna let her around you again.”
“What’s that supposed to mean?”
“Just that he was okay with letting her stay when he didn’t know you’d be home and he won’t be pleased to find out.”
“What the fuck, Shachi?”
“Come on. Don’t take it personally, you know how he can get-”
“Morning!”
“Good morning, Y/N!” Shachi says brightly and turns to the door opening where Y/N has appeared, only dressed in a loose bathrobe.
“How much did we drink last night? I have a raging headache,” she moans and shuffles lazily over to the sink.
“You did go all out,” Shachi chuckles. “Do you need anything? Aspirin?”
“I already took one,” she smiles. “It’ll be okay, although I was wondering if you guys could recommend some cafes nearby? Somewhere you can bring a laptop preferably.”
“You should go with Law! He’s currently writing research papers, so he can get you into the university library, the exclusive part of it,” Shachi grins widely. “The little cafe there is the cleanest place around, really.”
“Oh, I don’t want to impose,” she says to Law. “Any old cafe is fine really.”
“It’s no trouble, you can come with,” Law says, surprising himself. He never agrees to bring Shachi and Penguin around to his temporary office at the university, but a part of him is not against flashing his big-shot med-school fringe benefits in front of Y/N, hoping to somehow impress her. Just as friends of course.
“Thank you," she says with a wide smile. "Penguin told me you did residency at a hospital, are you done there already?”
“No, I still do-”
“Law does both. Simultaneously! Yeah, I know. Smartest guy I know. Real catch this one,” Shachi lays it on thick and Law wants to strangle him. Not only is it fucking embarrassing, it’s also inappropriate. This is Penguin’s girlfriend for fuck’s sake.
“Wow, I’ll take your word for it,” she says to Shachi, but she’s smiling at Law. He looks away.
“I’m gonna take a shower, I’ll leave in 30 min. Be ready by then if you want to come,” he says to the floor.
“Thanks, Law!” she calls out after him.
Before he closes the door to the bathroom he hears the sound of snickering from the kitchen. Fucking hell, are they making fun of him?
----
“So when do you graduate?” Y/N asks. They’re driving to campus in his pre-owned, pale-yellow suzuki. Driving is a hassle because he needs to take the long way around to avoid midtown traffic, but he’s got his own parking, so he won’t complain.
“I finished med-school last year and now I’m writing a PhD and doing post-graduate training.” Law’s grateful for how easy it is to avoid her gaze when he’s got his eyes on the road, but he still feels the pressure to keep a civilised conversation going.
“Post-graduate training?” she asks.
“The residency,” he explains.
“Ohh, wow. It’s so complicated becoming a doctor,” she says with a small chuckle. “You did 8 years and then on top of that you need more training.”
“Well, some people think it’s better to be over prepared when having the constant responsibility of real human lives in your hands,” Law says. It’s supposed to be a joke.
It doesn’t land at all.
When they get to the university, Law lets her into the small cafe at the bottom floor of his building and says, “I’ll drive back at 3, be ready at the exit by then if you need a ride back. The bus is also quite comfortable.” With that he flees up to his office on the fourth floor.
When he makes his way down to the first floor at 15.00 sharp, she’s not there. It’s a mild disappointment, but it does give him the opportunity to call his favourite person on the way home.
“Bepo, thank god,” Law says when he picks up the phone. “Shachi and Penguin are killing me over here.”
“Oh, no. What happened?”
“Penguin is travelling for a week and his new girlfriend is staying here while he’s away. I’ve never even met her before and he didn’t bother to tell me she was coming.”
“What? That doesn’t sound like Penguin,” Bepo says.
Law feels his cheeks heat up, not wanting to admit that he has fair share of blame in the situation. He wants Bepo to be on his side.
“Yeah, it’s weird, but anyway. How are you? It’s been a while,” he says.
Bepo is doing his residency out of town, which is how Law ended up living with Shachi and Penguin in the first place. Bepo used to live here. Law used to live alone. It would be a lie to say he’s never regretted the decision to change that.
“-but I think they’re warming up to me. Though I can’t be sure. Anyway, I’ll get by,” Bepo finishes.
“Everyone likes you, Bepo,” Law comments casually. It’s really the truth. He can almost hear Bepo blush on the other side.
“But tell me about Penguin’s girlfriend! I didn’t know he had one. I honestly thought he was-” Then he is cut off.
“Sorry, didn’t catch that last part,” Law says loudly. The car speakers might be going bad.
“I didn’t know he had a girlfriend!” Bepo repeats.
Law frowns. Bepo thought Penguin was what?
“Law?” Bepo calls out.
“Yeah, I’m here,” Law says, realising he turned quiet. “He told me a couple of weeks ago that there was someone and that he was hoping they would get together. He was really excited about it too. Although pretty shy concerning the details, didn’t want to tell me much. You know how he gets.”
“Eh, yeah…” Bepo says unsurely.
“You okay, Bepo?”
“Super! Is she nice?”
“Well, yeah. Or I don’t know. She’s kinda mean about Penguin,” he admits.
“Mean how?”
“Like calling him an idiot and stuff.”
“I see, yeah, that’s not nice.”
“It’s probably fine. He’s a grown up, he can make his own choices. Other than that she seems nice. She's really pretty.” Law winces over the fact that he felt the need to add the last part. It's unnecessary to let others know that he feels this way about her, even if it is just Bepo.
“What did Shachi do?”
“What?”
“You said he was killing you too?”
“Oh, yeah well… He’s just really friendly with Y/N, and I feel like they’re ganging up on me. It’s nothing big,” he says, pulling up to his usual street parking spot.
“Y/N?”
“Pen’s girlfriend.”
“Oh, weird.”
“Yeah,” Law says.
There’s a pause.
“So, are we still on for movies next week?” Law asks. “I’m staying from Sunday till Thursday. Most nights there’ll be a boring dinner, but I can catch something later in the evening.”
“Yes! Let's see the new Sora movie!”
“Again?” Law asks, as if he wasn’t thinking about suggesting it himself.
“Yes!”
Law laughs and says, “Looking forward to it. I’ll call you later in the week okay?”
“Okay! And good luck with the whole Penguin’s-girlfriend-situation!”
“Right,” Law sighs and cuts the engine.
That night Law goes to bed early. He lies in bed for hours, desperate for sleep to take him away, but sleep doesn’t come. When it’s like this he usually gets up and has a glass of water, a cup of tea, a cup of coffee if there’s really no chance of getting sleep, but tonight he forces himself to lie still and just try.
Because sleep would be the only thing that could save him now.
----
“Law,” she gasps.
“Yes?”
He looks around, but there’s no one there. He’s in a dark room, a few windows letting in beams of sunlight far up the wall, but they only make the rest of the room feel darker. The ground is dirty and he’s sitting on his knees. He tries to stumble his way up when the voice speaks again. He feels a burst of pleasure brought on by the sound and falls back down on his knees, a slicing pain spreading from his kneecaps down towards his feet.
“Law, do that again,” it begs him. It’s a beautiful voice, like silk, the soft feel of it strokes him pleasantly over his skin.
That’s when he realises that he’s almost naked. He’s wearing clothes, but they’re unravelling slowly, falling apart at the seams. The cold air kisses his skin as it part by part gets exposed.
“Law,” the voice says again, “I need you to touch me.”
“Yes,” he chokes out. “Where are you?”
Looking around, he still can’t see anyone else, but now the room is dimly lit by an open door letting in heaps of sunlight. It looks like he’s in a prison of some sort.
He’s not able to stand, but he staggers his way along the ground towards the opening. He can feel his clothes fall off him, one by one, and when he reaches the door he must surely be naked, but he doesn’t check.
The door leads out to a green meadow and when he reaches it, he can stand up. He runs out to feel the grass under the soles of his feet.
He turns and looks back at where he came from and sees that he was inside an enormous, old tower mill. Its long sails are circling in the wind and every time they reach the ground, they’re closing off the entrance from which he just came.
“Yes, that’s it. I’m ready now,” the voice sings in his ear, a lot closer than before and he turns in a whirlwind to see a heap of hay before him and amidst it a naked woman, writhing in pleasure.
“Now, Law,” she orders, opening her eyes to meet his’.
Law moves over to her and embraces her, sinking into her and she laughs out of pleasure. A melodic laughter that fills the world with sound and he lets go of the noises stuck in his chest. A long satisfied sigh, followed by a short grunt and a-
“Law,” she moans.
“Yes,” he answers. “Y/N, what do you need?”
“More.”
With a shudder it all slips away from him.
He’s in his own bed, sweaty and alone. He’s achingly hard and instinctively rubs himself to ride the high of the dream.
Fuck. It feels below him having a sex dream, especially about someone he just met and who-
A sound is heard and Law freezes up. No, it can’t be. He must be hearing things, maybe he’s still dreaming.
He hears it again.
A noise that sounds a lot like moaning.
Law’s room is at the end of the corridor and it’s the room that in theory should have the most privacy, but when the assholes who rented out this apartment renovated it, they found that making two rooms out of one would be profitable if they didn’t put too much money into materials. That’s why Penguin and Law’s room is basically the same room only separated by the thinnest of walls, making it impossible not to hear whatever’s going on in the other room at all times.
It’s always been a nuisance, but it’s never been this much of a catastrophe, because Y/N is obviously engaging in some kind of sexual activity and Law can hear it. He would do his best to ignore it, pop in some ear plugs and deny it ever happened, if it weren’t for the fact that the sounds are so delicious.
It’s crisp, each sound travelling through the thin walls without losing its quality. Law is able to differentiate what sort of actions might have spurred the different noises on, on a detailed level. He can hear when it’s pure pleasure and when it’s an aching need for more.
He starts imagining what she might be doing.
The obvious answer would be that she’s alone and masturbating, but what if she brought home someone? Someone who fucks her deep and slow, giving her just what she needs. Law reaches a hand down to touch himself again, but suddenly stops.
She’s with Penguin.
Even if she’s the type of person to do something like that, which he hopes she’s not, Shachi was hanging out with her tonight. He would stand up and put a stop to it before it came to that.
But what if she’s fucking Shachi?
It’s not believable, but the thought is kind of hot. They’ve been having fun this week. Going out, just the two of them. Maybe the tension became too much and they lost all control.
Once again he’s got to stop his hand from reaching for himself.
Shachi would never do that to Penguin and as long as Law has known him, Shachi has never shown interest in a woman. To think that he would all of a sudden change his sexual preference just so that he can cheat on his best friend is ludicrous. Maybe Law is projecting.
But of course Law wouldn’t do that to Penguin either. Just because he wants to knock on her door and offer up his assistance everytime he hears her making that sound, so close to begging, doesn’t mean he would ever act on it.
He wouldn’t.
But he’s got to do something. He needs to take care of himself or he will never be able to sleep afterwards. And these sounds are way too good to not take advantage of. Better than any porn. The perfect soundtrack to all his fantasies.
Fuck.
He spits in his hand.
Yes.
It sounds like she’s close now, the noises are getting quieter, but are coming more rapidly. It doesn’t take a lot before he’s close too. The dream. The sounds. The fantasy of having her on him, being the one getting her to make these sounds. It’s too much. He comes hard into his hand and can’t stop the groan that follows.
When he comes down from the high it’s suspiciously quiet from the other side of the wall.
Oh no.
She must have heard him and now she knows what he did.
He’ll never be able to look her or Penguin in the eyes again.
----
The next morning she doesn’t give him any reason to believe she caught on. If she did, she at least is not intending to make a scene about it. He’s eternally grateful. He can pretend to forget it ever happened if she is willing to do the same.
Law spends the next couple of days avoiding both Shachi and Y/N like the plague. He works long hours, he eats out, he stays out, he comes home late and leaves early in the morning.
By the end of the week he’s fucking exhausted, but he’s managed to keep himself out of any inappropriate situations, with absolutely no help from Shachi, who must have noticed Law’s awkward predicament and has been doing everything he can to put him on the spot. A single day hasn’t passed without Shachi texting Law, asking if he can help drive Y/N somewhere or give her a hand with something else. It's infuriating.
Speaking of, Y/N’s been getting increasingly more comfortable in the common areas, walking around mostly in Penguin’s baggy shirts and shorts. No bra.
It’s fine.
He's almost made it to the day of Y/N's departure without embarrassing himself when it all comes crumbling down.
In the middle of the night, there’s a knock on his door. He opens the door ever so slightly and peeks through.
"What do you want?" he asks gruffly.
It's Y/N holding up a bottle of wine.
"Sorry, did I wake you?"
Law gives a wave of dismissal, she did not.
"I was just thinking and, uhm, well I'm leaving tomorrow and I've hardly gotten the chance to talk to you. So, last chance to bond, I guess." She laughs nervously. "I heard you like white wine?"
It hits Law how much of an asshole he's been.
To her it must have seemed like he had no interest in getting to know her at all. Come to think of it, he’s been treating her as if he suspects she’s not gonna stick around. What if Y/N is the love of Penguin's life? And he treated her like garbage just because he couldn’t get over his own crush on her?
"Yeah, let me just," he says, going back into his room to put on a shirt.
"Wow, those tattoos really are rad," her voice rings way too close and he turns in a whirlwind. He left the door open and she had seen it as an invitation to come in.
He's about to ask her to leave his room, they can do this in the common area like normal people, but that’s when Y/N sits down on the bed and scoots up to lean into the wall.
He must have looked pretty appalled because next thing he knows she says, "I’m sorry, are you very particular about your bed? Should I sit somewhere else?"
Law doesn’t say anything because yes he is, but at the same time he really isn’t. And he can’t really ask her to leave his room now without sounding like an asshole, so he joins her on the bed, his heart rate picking up.
She opens the bottle and hands it to him, no glass, no cup. It even has a fucking screw cap. Jesus. To avoid embarrassing Y/N by being a total snob he takes it and takes a sip.
Fuck, that’s vile. This must be the cheapest riesling available.
"Shachi did those, right?" she asks, pointing at the tattoos on his chest.
He forgot to put on a shirt. A little late for that now.
"Yeah, he’s a really talented artist," Law says, shifting a little further from Y/N, now that he’s aware of how they’re almost touching. "He doesn’t do a lot of work anymore though. He's a teacher now. PE and swimming."
"He told me," she says, taking a swig of the wine before placing it on his bedside table. "You guys are so cool. I'm glad Pen has friends like you."
The mention of Penguin is enough to get Law to scooch an inch further away.
"Then there’s Bepo, you should meet him too. He lives out of town for now."
"Oh, I've met Bepo!" she says. "Big, blond guy, right?"
"Yeah, how did… when?" he asks her, confused. "When did you meet Bepo?"
"Last fall, I think," she says unsure. "He's great. Are you two close?"
Law can’t make out what to say. This makes no sense. Unless Y/N and Penguin must have been friends a long while before getting together. If that’s the case, it makes him feel even worse.
"I'm sorry I barged in and tried to force this whole thing on you. I just hated the idea of not getting to know you," she says. "You know, Penguin showed me your manifesto."
"My what?"
"Your manifesto? Three years ago, maybe four," she explains further, "you guys were at some party and everyone there were assholes, you got so angry with the world you decided to make a manifesto there and then? And then you-"
"Declared it at the party," Law finishes, wincing at the memory. They had been celebrating exams in the first year of med-school. "I was a fucking nuisance."
"It's a solid piece of work," she says with a chuckle. "Pen took a photo of the napkin you wrote it on and showed it to me that weekend. I thought you sounded like you were just the coolest person ever, so I tried following it for about a month."
Law looks at her, completely horrified. He remembers the embarrassment that is that so-called manifesto.
"Well, most of it," she adds. “Not number four.”
He snort-laughs loudly, remembering vaguely what he wrote and says, “I’m pretty sure I specified that the fourth point is directed at William, so you’re off the hook.”
“You’re right!” she exclaims.
"I was young," he explains, half jokingly. “Drunk too.”
Her laughter trickles like pearls on a string and Law catches himself smiling. He self consciously rubs himself across his chin, forcing the smile away.
"I've wanted to meet you for a long time, Law."
"Oh?" he asks, mouth suddenly dry.
She's a lot closer to him now. He can feel his will power is worn thin from all the push and pull through the week. He just wants to accept it. Accept her and take what she wants to give him. It's obvious now that she is coming on to him. This can't be anything else. Her eyes flutter, peeking down at his lips. Her hand is resting on his knee, making small circles with her finger tips. He wants this so badly.
When she leans in he's very close to meeting her half way, but instead he says, "You should go."
"What…? Really?"
"Yes," he says firmly, looking down.
"Okay."
She walks to the door and he follows her out. Before she leaves she grabs his wrist.
"Why?" she challenges him, forcing him to look her in the eyes.
“I can’t do that to Penguin,” Law explains.
“I thought you wouldn’t care about stuff like that."
“Then you got me wrong, because I do care."
“Come on, what’s really the problem? I’ve heard stories about you and your borderline questionable morals, you know,” she says teasingly, still holding a firm hold around his wrist. “I didn’t think you’d be bothered by silly rules.”
“Well, sorry to disappoint,” Law hisses, ripping his arm out of her grip. “I still have some dignity left, thank you very much.”
“What? Law, I’m sorry, I didn't mean-” she calls out after him, but he’s already closed the door on her.
What a fucking mess.
He collapses back on the bed, fighting the urge to groan loudly into his pillow. When he notices the bottle of wine still on the bedside table, he grabs it, intending to drown his sorrows, but then he takes a sip and-
Nope. No chance. That’s the most disgusting thing he’s tasted in a long time.
Ugh, it's gonna be a long night.
----
Penguin comes back the next morning and Law waits. He hears him leave his suitcase in his room. He waits. He hears him talk to Y/N and Shachi by the breakfast table. He waits. Then he hears the goodbyes, the dangling of keys and the slamming of a door. Only then does he dare to leave his room.
He sneaks into the kitchen, desperate for coffee and freezes when he sees it. Penguin is there all right, but so is Y/N. Shachi is nowhere to be seen. Law has made a grave error.
“Hi, Law!” Penguin says cheerfully. “You’re back early? I thought you would be gone till tomorrow.”
“Well, I’m actually not going until next week. They changed the dates a while back.”
Penguin frowns.
“Uhu, okay,” he says slowly, “so you’ve been… here, this week?”
Law nods, acting like everything is totally normal.
“Then I guess I won’t have to introduce you to-”
“Yeah, we met-” “We’ve already-” Law and Y/N say simultaneously.
“Great,” Penguin says, clearly displeased. “Just what I needed.”
“Oh, come on, Pen,” Y/N pleas. “Can you be normal about this?”
Penguin looks at her, then he looks at Law, then back at her.
“Oh my god, did you guys fuck?”
“What, no!” Law sputters.
“Please say it wasn’t in my bed,” Penguin moans.
“We didn’t do anything,” Y/N says.
“You know I don’t trust you an inch, you fucking snake,” Penguin says pointedly at Y/N.
“Ok, I admit I tried to, fucking sue me. But I was rejected,” she spits back at him.
Law is having real trouble understanding the dynamic of their relationship, but his main priority is to reassure his friend.
“Don’t worry, Pen. Nothing happened,” he says in all seriousness.
“Thank you, man. I honestly didn’t know if I could trust you on this,” Penguin says.
“Of course you can. I would never do that to you,”
“I can’t believe you’re on his side,” Y/N sighs. “You’re so immature, both of you.”
“He’s MY friend,” Penguin says childishly.
“Why on earth are you jealous? He’ll still be your friend even if I fuck him, right Law?” Y/N asks, looking expectantly at him.
Wait, what?
“I’m not jealous, is it too much to ask that my sister keeps away from my mates?”
Sister?!
“Yes, it’s weird. You shouldn’t care-”
“Guys, stop!!” Law shouts.
The two of them stop arguing and look at Law confused, and wow, they kind of do look alike when you think about it. Law is stumbling and has to grab a hold of the chair to keep his balance. He slides down into the seat.
“Hey, you alright there, buddy?” he hears Penguin ask.
“Your sister?” Law asks in a quiet anger. “You never said- I didn’t know you-”
“Law, speak up. What is it?”
“She is your sister?!” Law sputters as he looks up at Penguin.
“Yeah, how did you not know? You’ve been fucking her all week,” Penguin says bitterly.
“Oh my god, he did not-” Y/N butts in.
“ Shush ,” Law almost shouts at them. “You didn’t want us to meet because she is your sister?”
“Yeah, of course, I don’t want my sister to-,”
“I have been beating myself up over this all week, Pen,” Law says angrily, “because I thought that she was- If you had only told me from the start, maybe I would have known she was- And then I wouldn’t have had to…” Law wants to cry. "I've lost so much sleep over this."
“Law! Slow down,” Penguin says worriedly. “Who did you think she was?”
“Your girlfriend, Pen,” Law says bitingly. “You know, the one you told me about three weeks ago. You’ve never even mentioned a sister.”
In the background he can hear Y/N laugh quietly.
“Who do you mean my girlfriend?” Penguin asks, confused.
“Pen, I think he means Shachi,” Y/N says, biting down her laugh.
“No, of course I don’t mean Shachi,” Law says quickly. “I thought you were-” He stops himself and looks at her. “What? What do you mean Shachi?”
“We’re kind of a thing,” Penguin says blankly, looking at Law with unsureness. All annoyance and aggravation seeps out of Law.
“Oh,” Law says simply. “How long has- uhm, since that happened?”
“Couple of weeks now,” Penguin says slowly.
The two of them look at each other blankly.
“That’s… cool. I’m very happy for you,” Law says honestly, although somewhat strained.
“Thanks man, that’s- that’s very… yeah, thanks."
The silence is weird, mostly because of the big argument that raged on moments ago, which has now fizzled into nothing. Luckily for all of them, Penguin’s phone rings and he walks out of the kitchen to answer it, sending his sister a threatening glare before exiting.
"So you're siblings, huh?" Law asks her awkwardly.
"Yeah," Y/N says. "I've been abroad a lot, so we don't see each other very often."
"Ah," Law says.
This puts her actions into a slightly different perspective and Law is embarrassed by his own.
"I'm sorry about last night," he says. "I was mean."
"No, don’t worry about it," she says quickly. "It wasn’t fair of me to force you into that situation."
“Well, but I thought you were… as we already have established that you’re not. And that Pen was… which he isn’t," he says dumbly.
Long silence.
"Yeah, then that would have been cruel of me," she nods.
"It wasn’t on you, you didn’t know.”
“I’m just glad that it wasn’t because you hated me,” she says. “Penguin always talks about you and I was really looking forward to getting to know you.”
“No, not at all, I never hated you,” he reassures her. Memories from the past week come back to him. The looks, the touches, the dream. He feels warmth flooding to his cheeks and neck.
“I just had a lot of thoughts about you,” he explains, “and I hated myself for thinking that about Penguin’s girlfriend."
"But I'm not," she says slowly, "Penguin’s girlfriend."
"No, you're not," Law says, feeling a smile slowly spread.
"So, what kind of thoughts are we talking about?"
“The bad kind,” he says.
“Care to give me a demonstration?”
“I thought you knew all about me and my borderline questionable morals?” he asks pointedly.
“Oh my god,” she moans. “You must have thought me the worst person in the world.”
“Only the second worst,” he corrects, “after me of course. I almost gave in to you.”
“Oh?”
They move closer.
“For fuck’s sake!!” cries Penguin from the corridor. “I leave you alone for one minute and-"
Law’s manifesto
1. Fuck those guys who talk down, they’re not worth shit
2. We do it for the kids, not the profit
3. But we do need to live, so fucking unionize
4. Eat shit, William
5. Don’t let anyone treat Bepo like that

ᴄʜᴀᴘᴛᴇʀ 3 - ꜱᴛᴜᴅʏ ᴅᴀᴛᴇ
Summary: In the middle of exams and a diet of instant noodles, you decide to order some take out. What you did not expect was your delivery person to be a hot guy on a motorcycle, who, as fate would have it, happens to be a fellow student at your university.
tags.: One Piece, Trafalgar Law, Law x Reader, NSFW, slow burn romance (?), Modern AU, law has a motorcycle cuz its hot, Penguin, Shachi, Bepo appearing as flat mates
a.n.: study date with Law, and Penguin spotting you two, getting on Laws nerves <3
[ꜱᴛᴏʀʏ ɪɴᴅᴇx]
Despite your brief dive into his social media, the little information you’d gathered did reassure you that he was indeed, a med student. His profile was private, yet you could read his bio still. It barley stated anything, besides a stethoscope emoji and “North”. You also looked through the pictures he was tagged in and saw some posts with who you guessed were his friends. In none of the photos did he seem particularly happy—his face always distant, never smiling.
The snow in the background, along with his clear mention of “North” in his bio, made you think he came from the North Blue, a rich seaport country known for its scholars and wealth. It left you wondering how someone from such a place could have financial problems. If he really was from there, why was he doing food deliveries while in med school?
You guessed that explained his cold demeanor, though you weren’t entirely sure. Maybe it was more than just his roots—something deeper, more guarded. Law really was a mystery to you, you had to admit…
With a quiet sigh, you finally stopped fussing with your outfit and began packing for the study session. You tossed your things into your bag, grabbed your keys, and headed out the door. After a few bus stops, you arrived at the small café where you’d suggested meeting up. It wasn’t anything fancy—just a place you liked for its cheap coffee and soft music.
As soon as you stepped inside, your gaze swept the café, trying to find that familiar face.
In the far corner, away from the bustle, Law sat with a cup beside his laptop, his hoodie drawn low over his head. Strands of messy black hair peeking out, giving him a cozy but tired look. His long legs were stretched out under the table as he typed, oblivious to the world around him.
You inhaled deeply, steadying the butterflies in your chest, and made your way over. The excitement buzzing inside you was undeniable, you’d been so eager for today that sleep had been non-existent the night before. Somehow, you hadn’t expected things to get this far—having his number, meeting up. Even though it was technically a study date rather than a real date, which carried its own expectations, it still felt like a big step. The label “study date” took some pressure off surely. You didn’t have to worry about impressing him with small talk or charm, instead, you could focus on the shared exam next week. The thought was comforting—less about romantic interest, more about surviving this test together. Yet, deep down, the thought of sitting across from Law, even under the guise of studying, still set your heart racing.
As you approached his table, you hesitated for a moment, standing there, unsure if he’d noticed you. At first, he seemed unaware, lost in whatever he was working on. But then, sensing your presence, he paused and pulled an earbud from beneath his hood. He was about to give you a cranky look, yet when he noticed it was you, his frown shifted into a mild surprise, followed by a faint smile that made your heart skip. He straightened up slightly, his attention now on you.
"Sorry, didn’t hear you," he murmured, reaching for his other earbud and slipping it into its case.
"Don’t worry about it," you said with a smile, sliding into the seat across from him. As you placed your bag down and pulled out your study materials, you couldn’t help but ask, "What were you working on?"
Law watched you for a moment, his gaze following your movements as you got settled. At your question, though, he let out a deep sigh, rubbing his eyes in clear frustration. His posture slumped as he sank further into his chair, his knee almost brushing against yours under the table.
"Ugh, nothing much really," he grumbled. "A friend of mine is writing his thesis and asked me to look it over. He added so many puns it’s basically unreadable."
You couldn’t help the grin forming on your lips, and didn’t notice how this first conversation made you relax quite a bit. It felt more natural to talk to him like this, as if you two really were just uni colleges. It was quite the contrast to the delivery Law you knew. And he seemed to be at ease with your presence as well.
“I really have to see the puns…can I?” You asked with a light chuckle in your words, as you leaned a bit closer in anticipation. Law rolled his eyes with a light grin and turned the laptop towards you. There were quite a lot of comments on the document you saw, and a lot of them just said “???” or “ew”.
With one slender inked finger he pointed at the screen “This one is the worst…”
You leaned in closer, your eyes skimming over the highlighted text. It read: 'In the field of marine biology, things can get a bit... fishy.'
You snorted, clapping a hand over your mouth as you stifled a laugh. "Oh my god, thats bad.," you said between chuckles.
Law shook his head again, a heavy sigh escaping him, though a grin tugged at the corner of his lips as he saved the file and turned his laptop back towards him. “Anyway,” he said, straightening up, “I’ll finish that misery later. Let’s focus on biochemistry now.”
For a moment, you wanted to ask about his friends, curious to know more about the people in his life and maybe learn a bit more about him too. But Law was already shifting gears, getting straight to the point. It didn’t disappoint you exactly—just reminded you that, despite how at ease he seemed, there were still walls up. He was private, and it was clear he wasn’t the type to open up easily. Even though he seemed comfortable around you, this was still a study session.
“Sure,” you said, snapping back to the task at hand. “Topic 8, right? I finished up those cycles... let me grab them.” You rifled through your bag, pulling out your notes and spreading them across the table.
Law’s gaze drifted down, scanning the pages. They were well organized—every chemical structure carefully drawn, names and enzymes clearly labeled, with helpful mnemonics in the margins. You had even highlighted key enzymes in a way that made them pop without overwhelming the page with color. He didn’t say anything, but you caught the slight flicker of something in his expression. Was that... approval?
He gave a small nod, leaning in to take a closer look. “Yeah, this part,” he muttered, pointing to a specific reaction, “it just won’t stick in my brain.”
As he spoke, he absentmindedly rubbed his cheek, before looking up at you with those intense, stormy eyes. For a split second, you forgot how to breathe. It wasn’t fair how effortlessly handsome he was—sharp features softened just enough by that calm voice. And here you were, supposed to be focusing on biochemical reactions, not him.
You cleared your throat, trying to pull yourself together. “Uh, yeah, this one's tricky. But the mnemonic I used really helps—let me walk you through it.”
Law’s gaze stayed locked on yours a moment longer than necessary, and for a heartbeat, the air between you felt heavier than it should. But then, just like that, the moment passed, and you were back to studying.
This was definitely going to be harder than you thought.
After hours of intense studying, testing each other with questions you thought might appear on the exam, you both hit a wall. The material was exhausting, and your head was beginning to throb. Law, who was usually so composed, seemed more drained than usual. He kept rubbing his face and leaning back in his chair, while you let out a sigh every now and then.
"Think we're done for the day?" you finally asked, the weight of your tiredness catching up with you.
Law gave a small nod, looking equally worn out. "Yeah, pretty much."
Packing up your things, you both stood up and made your way out of the café. As soon as you stepped outside, you noticed the sky had darkened, and the evening had settled in. You zipped up your jacket, slipping your hands into the pockets to ward off the chill. Law paused for a moment, glancing down the street in silence, before he turned to you.
“Where are you heading?”
The question hung in the air, casual but with a hint of something else. You knew he wasn’t offering to walk you home—Law didn’t seem like the type to make those kinds of gestures. But if you were headed the same way, it wouldn’t make sense not to walk together. Besides, you had to admit, a part of you hoped your routes would match up, giving you a little more time with him outside of studying.
You nodded towards your direction. “Just heading to catch the bus.”
Law simply gave you an approved hum.
A small rush of relief washed over you as you both started walking together in comfortable silence. Law wasn’t great at small talk, but somehow the quiet wasn’t awkward. There was something reassuring in just sharing the space with him, without the need to fill it with forced conversation.
The rhythmic sound of your footsteps filled the void between you, yet got distracted when someone from behind was starting to yell.
"Yo, Law!"
The sudden shout made you freeze mid-step, and you turned around, startled. Law, on the other hand, immediately pinched the bridge of his nose, clearly recognizing the voice and not being pleased about it. He let out an annoyed sigh, his irritation evident as he turned to face the approaching figure—Penguin.
As Penguin jogged over, Law’s annoyance only deepened.
“Do I know you?” Law deadpanned, cocking an eyebrow at the young man who now stood grinning before the two of you.
You wished you could run away and hide immediately, trying not to admit that you recognized Penguin from Law’s social media. A sense of shame crept in—stalking his profile hadn’t been your finest moment, but curiosity had gotten the better of you. And now here you were, face-to-face with one of Law's closest friends, feeling oddly exposed.
Penguin, unfazed by Law's sarcasm, chuckled. "Ha, ha, very funny. What are you doing out here?"
Before Law could answer, Penguin’s eyes shifted to you, his smile faltering briefly as surprise flashed across his face. Then, as if putting pieces together, his expression morphed into a knowing grin that made your stomach flip. Law could see it coming a mile away.
He glanced back at Law with a mischievous glint in his eye, clearly ready to stir the pot. “Is this your girlfr—”
“No.” Law cut him off sharply, his voice cold and final, giving Penguin a glare that could have frozen water. “What do you want?”
Penguin raised his hands defensively, the grin still plastered on his face. “Alright, alright, geez. Just wanted to say hi.”
For a moment, you stood awkwardly between them. Law’s frustration with Penguin was unmistakable, but it was hard to miss the closeness between the two. Still, the tension in the air was thick enough that you almost wanted to step away and give them space.
Law rolled his eyes, sighing quietly before shoving his hands into the pockets of his hoodie. "Studying and reading over your thesis. I’m not finished yet, though."
Penguin waved it off with a casual gesture, looking genuinely grateful that Law had even taken the time to read through it. You were surprised by how civil Law was being—especially after all the grumbling he'd done earlier about the puns. But he didn’t bring that up. Not a single complaint. This brief interaction gave you a deeper glimpse into Law. You couldn’t help but hope that cold, cutting stare would never be aimed your way, even though Penguin seemed to be used to it and taking it lightly.
"No biggie, take your time," Penguin replied, still grinning. Then his eyes flicked between you and Law. "Hey, you guys walking home? Mind if I tag along?"
You felt a twinge of disappointment, secretly wishing you and Law could’ve had just a bit more time alone together, but you knew better. Penguin was his friend, and you couldn’t exactly say no. Law, true to his nature, simply nodded, giving you no real choice in the matter.
The three of you started walking down the street, the night air cool but not uncomfortable. It wasn’t long before you realized you’d have to split off, your route separating from theirs. From their easy back-and-forth, you figured out that they were flatmates, heading home together. When the time came to say goodbye, the parting was brief—Law’s nod short and polite, Penguin throwing you a casual wave.
You boarded the bus, your thoughts still lingering on the evening, hoping you'd have the chance to arrange another study session with Law soon.
As you disappeared down the street, Penguin couldn’t help but shoot Law a sidelong glance. “So... who’s she?”
“Uni colleague.”
Penguin raised an eyebrow, a knowing smirk tugging at the corner of his lips. “You never meet up with people from your uni.”
“Apparently I do.”
“Since when?”
“Since now,” Law snapped, his voice a little sharper than necessary. “Now leave me alone, for God’s sake.”
Penguin chuckled, but didn’t push further, knowing well enough that Law didn’t like talking about his personal life. Still, he couldn’t shake the curiosity. In the years they’d lived together, Law had never met up outside of classes with anyone from med school. He always studied alone, either holed up in his room or in the quiet corners of the library. Law had always claimed studying with others was inefficient, a waste of time.
Yet, here he was.
