Universality

Universality is a profound and foundational concept in science and mathematics that describes the property by which systems with vastly different microscopic details exhibit the same macroscopic behavior. It is most prominently observed in the study of critical phenomena in statistical mechanics, but it also emerges across a wide range of disciplines, including condensed matter physics, dynamical systems, chaos theory, mathematics, computer science, and even certain branches of economics and biology. The notion of universality provides a framework for understanding how complex behavior can emerge from simpler rules and how such behavior can be characterized independently of specific details, relying instead on symmetries, dimensions, and collective properties.

The concept of universality originated in the mid-20th century, particularly in the context of phase transitions in statistical physics. Physicists observed that vastly different physical systems—such as magnets near the Curie point and fluids near the liquid-gas critical point—exhibited strikingly similar behavior near their respective critical points. This was paradoxical because the underlying microscopic interactions in these systems were entirely different.

The resolution of this paradox came with the development of the renormalization group (RG) theory, primarily by Kenneth Wilson in the 1970s. RG provided a rigorous framework to explain how systems at different scales could be related through scale transformations, and how certain large-scale behaviors are invariant under these transformations. Universality emerged naturally from this framework: systems that flow toward the same fixed point in the space of physical theories under RG transformations exhibit the same critical exponents and scaling laws, regardless of their microscopic details. This laid the foundation for a deep understanding of universality and marked a turning point in theoretical physics.

A central feature of universality is the classification of systems into universality classes. These are groups of systems that, despite differences in their microscopic structures or interactions, share the same set of critical exponents, scaling functions, and general behavior near criticality.

The primary determinants of universality classes are:

Dimensionality of the system – The number of spatial dimensions significantly affects the critical behavior of a system. For example, the Ising model in two dimensions has different critical exponents than in three dimensions.

Symmetry of the order parameter – The nature of the symmetry breaking involved in the phase transition plays a key role. The Ising model, with a discrete Z2 symmetry, belongs to a different universality class than models with continuous symmetries like O(N) (e.g., the XY and Heisenberg models).

Range of interactions – Systems with short-range interactions often belong to different universality classes than those with long-range interactions.

Conservation laws and dynamics – In dynamical systems, the conservation or non-conservation of order parameters (such as energy or magnetization) can define dynamic universality classes distinct from their static counterparts.

Examples of well-known universality classes include the Ising universality class (scalar order parameter with Z2 symmetry), the XY universality class (vector order parameter with U(1) symmetry), and the Heisenberg universality class (vector order parameter with SO(3) symmetry).

The renormalization group (RG) formalism is essential to the modern understanding of universality. It describes how physical systems behave under changes in scale, allowing for the systematic "coarse-graining" of microscopic details while retaining the large-scale features that determine macroscopic behavior.

The key idea in RG is that as one examines a system at increasingly larger scales, the effective parameters governing the system’s behavior flow under RG transformations. At critical points, these flows approach fixed points, which correspond to scale-invariant behavior. Systems that flow toward the same fixed point share universal properties—hence the emergence of universality.

In this context, critical exponents describe how physical quantities diverge near the critical point (e.g., specific heat, susceptibility, correlation length), and these exponents are determined by the properties of the RG fixed point, not the microscopic details of the system. For instance, the critical exponent β, which describes how the order parameter vanishes near the critical temperature, is the same for all systems in the same universality class.

While the concept of universality originated in statistical mechanics, its implications extend far beyond that domain.

1. Dynamical Systems and Chaos

In the study of deterministic chaos, universality appears in the context of bifurcation theory and the transition to chaos. One of the most striking examples is the Feigenbaum constants, which describe the rate of period-doubling bifurcations in one-dimensional maps such as the logistic map. Regardless of the specific form of the map, the ratio of intervals between bifurcations converges to the same universal constant (~4.669), and the scaling behavior near the onset of chaos follows universal laws. This indicates that the transition to chaos in wide classes of dynamical systems exhibits universal features.

2. Quantum Field Theory and High-Energy Physics

Universality is also a key idea in quantum field theory (QFT), where it helps explain why effective field theories at low energies can be described using a limited set of relevant operators, despite the potential complexity of high-energy (UV) theories. RG methods show that low-energy phenomena are governed by universality classes characterized by the relevant operators at an IR (infrared) fixed point.

In lattice gauge theories and studies of quantum critical points, universality informs the scaling behavior of observables near quantum phase transitions, which occur at absolute zero and are driven by quantum fluctuations rather than thermal ones.

3. Computer Science and Algorithmic Universality

In theoretical computer science, a different kind of universality appears in the concept of computational universality, particularly in Turing completeness. A computational system (e.g., a Turing machine or lambda calculus) is said to be universal if it can simulate any other computational system. This form of universality is foundational to the theory of computation and underlies the universality of general-purpose computers.

Cellular automata also exhibit universality. For example, Conway’s Game of Life is computationally universal, meaning that it can simulate a Turing machine despite its simple local rules.

4. Percolation, Fractals, and Geometry

Percolation theory provides another domain where universality emerges. Near the percolation threshold, properties like the size of connected clusters exhibit power-law distributions characterized by universal critical exponents. These exponents depend only on the dimensionality of the system and not on the microscopic details of the lattice or geometry.

Fractals, which exhibit self-similarity and non-integer dimensions, are also associated with universality. The fractal dimensions of certain critical clusters (e.g., in percolation or the Ising model) are universal and can be related to the scaling laws governing the system.

Although more speculative and less rigorously defined, analogs of universality have been proposed in biological and economic systems. For example, scaling laws in biological systems—such as the relation between metabolic rate and body mass (e.g., Kleiber’s law)—exhibit regular patterns across a vast range of organisms. Similarly, certain macroeconomic behaviors, such as power-law distributions in wealth and income or the scaling of urban infrastructure with population size, have been argued to reflect universal principles.

However, unlike in physics, the presence of complex, adaptive agents and feedback loops in these systems complicates the identification of precise universality classes or fixed points. Nonetheless, attempts to apply statistical physics and RG-like methods in these fields continue to be active areas of interdisciplinary research.

Universality in a formal mathematical sense often involves invariance under group actions, limit theorems, or fixed-point theory. For example:

Central Limit Theorem: One of the simplest manifestations of universality in probability theory. It states that the distribution of the sum of many independent random variables tends toward a Gaussian distribution, regardless of the underlying distribution, provided the variance is finite.

Random Matrix Theory: In the study of eigenvalues of large random matrices, universality appears in the distribution of spacing between eigenvalues, such as the Wigner-Dyson distribution. These distributions are universal across broad classes of ensembles, including those modeling nuclei, disordered systems, and even zeros of the Riemann zeta function.

Scaling Limits and Universality in Stochastic Processes: Brownian motion, the scaling limit of many discrete random walks, provides a classical example. Similarly, the Kardar-Parisi-Zhang (KPZ) universality class encompasses a wide range of stochastic growth models that, despite different dynamics, share the same large-scale statistical properties.

Universality challenges reductionist viewpoints by emphasizing that many macroscopic behaviors are insensitive to microscopic details. This has profound implications for how scientists model and understand complex systems. Rather than focusing on the exact microscopic state of a system, one can study representative models that capture the relevant symmetries and conservation laws to extract universal predictions.

It also exemplifies the power of abstraction and the importance of symmetry and scaling in nature. The idea that fundamentally different systems can exhibit identical critical behavior suggests that there are deep organizing principles underlying complex phenomena.

Furthermore, the concept has epistemological significance, influencing how knowledge is structured and how laws of nature are interpreted. It bridges the gap between the particular and the general, providing a unifying framework for diverse phenomena.

Universality is a cornerstone of modern science, offering a window into the fundamental structure of complex systems. From phase transitions and critical phenomena to dynamical chaos, quantum fields, algorithmic computation, and beyond, universality reveals the deep and often surprising regularities that transcend specific details. Its discovery and formalization represent one of the most profound insights in 20th-century physics, with ongoing implications for a broad range of disciplines in the 21st century. As science progresses, the principle of universality continues to guide our understanding of emergent behavior, scale invariance, and the interconnectedness of nature.

BETWEEN FORMULAS, FLOWERS AND FEELINGS - SATORU GOJO

You are the imbalance in Satoru’s logical and rational reasoning.

pairing: nerd! gojo x student council president! reader

summary: being the student council president isn’t the easiest job in the world. It’s not like gojo — with his trademark glasses, his awkward smile hiding the most dangerous brain. because for him, he can resolve every problem, right? there is no formula that can escape his smart mind. not even you. so when he accepts to tutor you, could he really be sure feelings won’t become a new variable?

warnings: +18 MDNI, nsfw, smut, virgin! gojo, first time, oral (m! receiving), pinning, college AU, shojo vibes, quantum physics subject, slight angst, fluff, idiots in love, insecure! gojo, nerd gojo with glasses is hot, art by @/3-aem.

wc: 9,922

Ever since he was little, Satoru Gojo seemed to have been blessed with knowledge.

His very first Christmas toy — when he was finally old enough to have one — was a huge playset containing chemical transformation recipes to prepare by himself, using a handful of formulas and calculations.

When he turned ten, his parents gifted him a kit that allowed him to build his own electric train circuit, which he had to assemble using physics methods so that real electricity could power his trains — and sometimes even his cars.

By the time he reached middle school, scientific subjects like physics and chemistry became his second mother. Nothing escaped him. Formulas, molecular mechanisms, and chemical transformations held no secrets. This passion for complex methods shaped his logic.

For every problem, Satoru always found a solution. To him, the world was nothing but a set of solvable scientific probabilities, where nothing could slip through his grasp.

But growing up with barely controllable hormones… poor Satoru had experienced firsthand just how bitter that could taste, even at university.

The first time he asked a girl from his middle school to go out with him in his third year, Satoru never would have thought she’d laugh right in his face before calling him a useless nerd.

He didn’t let anything show. And yet, it was from that very day that Satoru’s glasses, his passion for science, and his own self-confidence betrayed him.

He decided to give up on feelings — classifying them as a deceitful, unscientific belief with a complete lack of logic, something better suited for grotesque purposes like the movies or romantic TV series that entertained uncultured people.

Satoru didn’t need emotions when logic always prevailed, never once disappointing him.

But upon entering university, he could never understand why — despite his silence and absolute discretion, buried in his studies — his cerulean blue eyes always seemed to find their way back to you.

You were the student council president of the school. Known for your upright mind, flawless organization, and a sense of justice so firm it sometimes bordered on harshness.

You had no time for anyone. You spent your days planning university events without wasting a single second — a notebook always pressed against your chest, and occasionally, a pair of glasses perched on your nose during intense activities like studying for exams or arranging event halls, which were regularly occupied by you and your staff.

What intrigued Satoru the most about you was your logic.

You planned everything, organized everything, all while maintaining grades nearly as excellent as his. You never wasted time hanging around with those ridiculous girls who would likely reject him if he ever dared to speak to them, and he had already admire witnessed you standing up for people like him — those trapped in their introversion and buried in their books — refusing to tolerate the injustice caused by the school’s most popular students.

A deep respect radiated from you.

Something Satoru refused to admit. Even though he knew you could short-circuit his brain in an instant.

Like that time when you had asked him for a pen at the library during your study session because he wasn’t far from your table. His face had turned crimson, and he could have sworn smoke was coming out of his ears. His mouth — so used to speaking with precision and efficiency — completely failed him in front of you.

The words got stuck in his throat, and the few sounds that miraculously managed to escape were nothing but incomprehensible stutters, earning him a confused frown from you.

In the end, he gave up on any attempt at conversation and simply handed you the best pen in his pencil case — his favorite. And he had almost silently prayed in his head that you would forget to return it so that you would keep it with you.

And he hated that.

This power you had over him — the way you made him nervous, shy, and desperate for you.

Just like in middle school.

Something he had sworn to leave behind.

~~~~

“NO, NO, AND NO!”

The event hall falls into a deathly silence as you shout your words with such force and vehemence that your fists crush the few sheets of paper still clutched between your tense fingers.

No one dares to move anymore — a part of the staff is busy moving boxes of decorations, two others are handing you papers to sign, some are hovering around you with questions, and others are amusing themselves by climbing ladders to place Christmas decorations — as if your scream alone has just pierced through the entire university.

With your jaw clenched, a vein pulsing at your temple, your cheeks flushed with anger, and your throat slightly irritated, you struggle to breathe as all attention shifts onto you.

“I said I haven’t decided on the organization of the Spring Formal yet, that nothing is supposed to be taken out, signed, or even requested until I’ve given the order, so what the fuck are you all doing here?!” you exclaim.

You push past the students in your way and snap your fingers at the two idiots fooling around with the decorations.

“You two — you’re fired.”

Then, you turn to the rest of the group handling the boxes. “If you don’t want to be fired too, hurry up and put that away!” Next, to the members waiting for you to sign papers. “Out!”

As the room empties in silence, filled with sulky and terrified faces at the thought of dealing with you, you take a deep breath before crouching down to the floor, burying your face between your knees, your arms trembling.

There isn’t much time left.

Director Yaga has given you a deadline to organize the Spring Formal, leaving you in charge of the theme, the venue, and the entertainment.

But, for the first time in your role, you are literally overwhelmed.

For the first time as well, no inspiration comes to you. The stress of classes, exams happening at the same time as the event date, your poor grades lately, and the pressure your team keeps adding on top of all that—at some point, you were bound to explode.

With all of this piling up, how are you supposed to manage?

That’s exactly what you asked yourself during your class that very afternoon, staring at your 40/100 in quantum physics.

With your heart sinking into your stomach, you hastily shove the paper into your bag, not caring in the slightest if it gets crumpled.

No one must see that the student council president allows herself to yell at her team while having such catastrophic grades. But your overloaded schedule no longer allows you to focus on your studies alone — how can you concentrate and stay organized when all you want to do is throw yourself out the window?

~~~~

“You need to register to require a tutor.”

“But I don’t need one.”

The male student raises an eyebrow. “So what are you doing here?”

You scoff. How dare he talk to you like that?

You’re in the library, one of the most soothing and stressful places in the world. You’ve had to find a way to get your grades up while you sort out your problem with Spring Formal, but in the meantime, you need to find a student who can tutor you without anyone knowing.

So what better way to find out than from the librarian’s assistant — who is also one of the Tutoring Center’s organizers?

“I need to know who’s the top student in quantum physics here,” you insist with a firmer tone.

Forgetting you’re at the entrance to the library, you purse your lips, a little embarrassed.

“We don’t have ‘top students’, prez,” he replies with a bitter smile — ah, so he knows who you are.

“So how do you help the students?” you ask with almost indignation.

He shrugs. “If you need help—”

“I do not,” you cut him off coldly, cheeks on fire as you adjust your bag over your shoulder. You sigh in annoyance at the student’s lack of efficiency.

“Then, how can I help you?” He gives you the most impertinent smile in the world, as if he’s just waiting for you to get the hell out.

You tuck a stray lock of your hair back behind your ear before rolling your eyes. “I need to talk to a top student in quantum physics, that’s all.”

The student looks at his fingernails as if they're the most important thing in the world and mimes huffing. “We don’t have any.” He looks up at you. “If you’re looking for one, there’s a nerd who’s the best in his class.”

Curiosity pricks the back of your neck, causing you to sit up straight. “Who?”

“Gojo, I think,” he said, frowning as if to remember his name. “Sato-thing, if I remember. Anyway, a nerd. You should know him, I guess.”

You shake your head, eyes almost squinting as you seek the memory of a Gojo name. But nothing comes to mind. So you shrug.

“What does he look like?”

“Albino. Blue eyes, nerd glasses, always dressed in a sweatshirt or shirt and he always has a book under his arm.”

“All right, thanks.”

Then you hurry out of the library and its oppressive walls, leaving the assistant to sigh with relief — as much as you do.

~~~~

“So, you are… Gojo Sato-thing?”

He has a little disappointed smile. “Satoru Gojo, prez.” With a nervous gesture, he places the strap of his shoulder bag back on his shoulder and adjusts his glasses, which slide down his nose.

You stare at him motionless for a few seconds, speechless at the all-too-perfect likeness of the Tutoring Center manager’s description. He’s got a book under his arm, a Digimon t-shirt over a dark blue plaid shirt and an innocent look on his face — he really wasn’t wrong.

You blink. “Um… yeah. Whatever.”

You check that no one in the corridor of the quantum physics wing has left any students lying around who might surprise you with him, then let out an exhausted exhale.

Faced with his 6'3, you owe it to yourself to raise your eyes and chin a little higher.

“I need your help. You're the best physics student in the class, right?”

He turns the toe of his shoe as a tic on the floor and nods imperceptibly.

“Perfect. I’ve got a little problem right now and—”

“Do you need me to do an assignment for you?” he says almost as if trying to divine your thoughts — is that hope you see in his eyes?

“No.” You knit your brows. “I’m having a problem with my grades and I’m swamped with my event responsibilities and I'm starting to get grades...” You chew the inside of your cheek to hide your pride before muttering, “...pretty bad. And I don’t feel like being given help publicly.”

In his confused expression, you add, “Otherwise it would be a real shame...”

From his height, Satoru’s shyness almost flies away in a gust. He’s got you there at last. In front of him. Talking about something. Like a dream come true — a reality where he no longer knows what his name is but whatever.

He even perceives a blushing creeping up your cheeks as you drift your gaze a little lower to your own shoes and your lips crumple into an adorably embarrassed and frustrated little pout.

Then of course he’ll help you.

He would give you more if he could, and he promises to himself he’ll do it.

“So you need me as your secret tutor?” he clarifies so softly.

You look up at him, clearing your throat. “Basically… yeah.”

“Fine. I can do that.” A small smile spreads across his pink lips and he digs his hands into his jeans, which are a little baggy for him.

You flicker your eyes, confusion animating your features. “Is that all?”

“Do you need anything else?” And you’d have sworn you saw hope still shining in his ocean-blue irises.

“What? No,” you retort incredulously. “But don’t you need something in return? Like, money or something?”

“...No,” he exhales, reducing his smile — though it still lingers. “I don’t mind helping you. Just give me your free hours so we can set a date. If that’s okay with you, of course,” he hastens to add, as if afraid of upsetting you.

Your lips part slightly. “O-Okay,” you finally say. “I’d like to do this as soon as possible.”

“How about today?” Satoru suggests, with a little more enthusiasm than he had anticipated himself. “Or even now, if you want.”

“Now?”

“Yeah,” he says with a happy nod.

“Don’t you think it’s a bit too earl—”

Barely ten minutes later, you find yourself sitting next to him once again in the library, which, for once, is not too crowded, pretending to have a casual conversation while, in reality, he is analyzing your failed test papers with an expert eye.

One elbow resting on the polished wooden table, one hand holding one of your sheets between his fingers, and the other with his index and thumb supporting his chin, Satoru lets his gaze travel line by line over your flawless handwriting—so much so that he forgets he’s supposed to be concentrating on helping you.

And not on the pretty way you write the letter ‘S,’ wondering how close he’d be to a cardiac arrest if he ever saw his name written by your hand.

When he finally manages to analyze the mistakes on your paper, Satoru straightens slightly in his seat, adjusting the collar of his unbuttoned shirt that suddenly seems to be strangling him with an invisible noose, despite his neck remaining completely free. His heart pounds at the speed of light — almost literally.

Calculations and formulas have always been child’s play for Satoru; his brain has always been wired for logic, rationality, and the addictive thrill of adrenaline coursing through his veins when he makes a new discovery, a new analysis that falls perfectly into place — like completing a puzzle and watching it come to life, or like a house of cards standing strong until the slightest imbalance brings it all crashing down.

You are the imbalance in Satoru’s logical and rational reasoning.

For Satoru, love is not a science. It’s just hormones that one must learn to control and not be fooled by.

And yet, even though he has devoted his body and soul to science, his heart will never cease to be yours — under your implacable and irrevocable hold.

Even with all the scientific weapons in the world, he will always be powerless before you.

With a flutter of snowy lashes, he returns to reality, setting his gaze on yours; persistent, waiting for him to say something, to give some kind of critique.

His mouth goes dry, heat rushes to his cheeks as he clears his throat, embarrassed.

“Well, uh... I guess we can start revisiting the notion of The Uncertainty Principle, if that’s okay with you.” He gives you a quick glance so unconfident that you restrain yourself from doing what you're thinking of: ripping off his adorable cheeks — adorable? Since when do you find nerds adorable?

“Okay,” you say, pulling a draft sheet closer.

As you move your chair closer to his to concentrate better thanks to the proximity, the effect is quite the opposite on poor Satoru. He nearly loses all composure when his trembling fingers close around his pencil.

“W-Well… Um, do you want me to give you a quick lesson on this again? You didn’t seem to grasp much of the concept.”

“If you can use simple words…” you mumble without much hope.

He swallows hard before explaining, “A rule in quantum physics says: you can’t know both the exact position and momentum of a particle at the same time. The more you know about one, the less you know about the other. Got it?”

You squint, uncertain, as you rest your chin in the hollow of your palm. “Mh-hmm…”

“So,” he draws two Delta symbols, each followed by an x and a p, then an equal sign, “this one represents the uncertainty in position while the other represents the uncertainty in momentum.” He leans slightly forward to clearly define the terms for you before breaking down the formula, trying not to sweat under the ghost of your breath caressing his hand because of how close you are.

“Okay. I don’t think I quite got all that.”

“It’s okay,” Satoru replies with a slight smile as he adjusts his glasses on his nose before returning to the sheet. “You confused uncertainty with actual errors in measurement, and you tried to calculate exact values for both position & momentum, which isn’t possible.” He draws an example of throwing a ball vs. tracking an electron. “You can’t pin down a quantum particle perfectly — it’s like me trying to figure out what you’re thinking all the time. Impossible, right?”

“...Right.”

“You don’t understand anything, right?” he sighs, a slight frown curling his lips.

“Honestly? Not a word,” you chuckle, a soft, honest melody that caresses his ears.

“Let’s make it more real for you, prez, then,” he snorts too, wiping away a big smile that deepens his dimples. “Imagine you’re running around campus planning this big Spring Formal thing. If I try to track exactly where you are at one moment, I have no clue where you’ll be the next second. But if I focus on how fast you’re moving between meetings, I can guess you’ll end up in the library… but I won’t know the exact second you get there. That’s basically the Uncertainty Principle — can’t have both at the same time.”

“Ohhhh, okay!” you say, a light illuminating your face. But a second later, your features drop. “But, wait… that doesn’t make sense. If we have better tools, we can just measure both, right?”

He chuckles softly. “Nope. Even if we had the best measuring tools in the universe, the universe itself won’t let us know both at the same time. It’s not a technology problem — it’s just how nature works.”

You groan, frustrated, and slump over your notes. “Physics is pain.”

He shakes his head, a lighter smile blooming on his lips. “You’ll get it, I promise. You just need time… and a good tutor.”

“You?” You snicker, but not meanly — just teasing him in this mood that feels so comfortable with him, something you never thought you’d experience. “You’re losing me more than I was before.”

You both sigh after a while, and he gives you a practice exercise, which you rush to complete so he can correct it.

For the first time in maybe weeks, or even months, you haven’t felt this light. Quantum physics has always been a difficult challenge to overcome, despite your habit of planning everything to avoid stress. But sometimes, doing everything alone has led you to not ask for help when you needed it the most.

So when someone reached out and showed you how relieving some of that weight could feel, the sensation sparked a desire in you — one that didn’t want this to end.

But you’re afraid it will make you dependent.

So it’s best not to get too attached, right?

~~~~

The following week, even though your understanding of quantum physics has somewhat improved, your stress refuses to do anything but skyrocket toward a full-blown anxiety attack.

Principal Yaga summoned you to his office because some students — the two you expelled last week — went to complain about your nervous and excessive behavior, claiming it warranted psychological support.

Outraged, you defended yourself by pointing out the inefficiency of your team, who fail to meet your needs without considering the mental load that comes with your responsibility as the student council president. And yet, that wasn’t enough to calm Yaga, who dismissed you with a stern reminder that if you don’t finalize the Spring Formal preparations soon, he won’t hesitate to replace you with a more competent organizer.

The mere thought — no, the haunting fear—of being replaced like a cheap supermarket doll plagues your nights with nightmares.

So, the obvious anxiety growing inside you bleeds into the most crucial moments — the moments when you’re supposed to stay focused instead of silently wallowing in your situation.

“Need help, prez?”

Ripped from your daze, you lift your gaze to the voice beside you, only now realizing that he’s been sitting next to you since the start of the lecture — completely unnoticed, completely ignored.

It’s Satoru, his laptop open in front of him, a small, friendly smile turned toward you—and only you. That tiny detail sends a strange, foreign wave through your stomach — not unpleasant, though.

“Oh, you’re here,” you mumble, turning your attention back to the professor.

“Since the very start, yes,” he replies, his voice softer now, tinged with a faint hint of disappointment as he twirls his pencil between his long, nimble fingers.

A silence settles between you, neither of you seeming inclined to break it.

In the lecture hall, only the sound of keyboards clicking and the amplified voice of the professor fill the large room. You try your best to follow along, scribbling notes as diligently as you can, but at this point, it feels like trying to form words by randomly pressing keys — you understand nothing.

“Need help?”

You slowly lift your head toward the familiar voice.

“You can explain it to me later, you know?” you mutter, careful not to let anyone else overhear your conversation — it could cost you.

“And we could save time by explaining it now.” His tone is soft, rational, kind, altruistic — every synonym that embodies maturity and gentle responsibility.

He’s made of sugar. Just for you.

You sigh, finally giving in with a nod, as Satoru flips his laptop into tablet mode to explain the purpose of the chapter — the name of which you’ve only just learned, despite an hour and a half of lecture on Wave-Particle Duality.

“So,” he says, writing the formula on his tablet with a stylus. “The general concept is quite easy. Quantum objects — like electrons — can act as both particles and waves, okay?”

You nod, leaning in closer to his shoulder to observe the definitions of the formula’s terms — a faint scent brushes against your senses. Clean laundry and a subtle drop of cologne. The scent imprints itself in your lungs pleasantly enough that you have to mentally slap yourself to keep from getting distracted from Satoru’s explanations.

He glances at you with those sharp blue eyes and raises an eyebrow. “You know what wavelength means?”

“It’s just for light, right?”

He snorts quietly. “Particles.”

“Oh.”

He holds back another laugh and continues his explanations.

Several minutes later, you find your eyes glued — no, entranced — by Satoru, this nerd with glasses that hide a brain far too brilliant for you. Maybe even for the entire university.

You notice it in everything he does — setting aside his physical appearance, which you’re starting to find cuter and cuter without even realizing it — every cell of his body breathes science, logic, the thirst for discovery. His brain analyzes every possibility, his fingers manipulate rationality, and his glasses help him weigh the pros and cons. His long, straight nose gives him an infallible instinct, a sixth sense that never fails, and his smile — his pretty, thin, pink lips—illuminate hypotheses with a dangerously innocent charm.

But he himself doesn’t even realize it.

“See? It’s like… imagine if you could be both a super serious president and a total mess at physics at the same time. Oh wait — that’s already happening,” he teases, a playful, cute smile blooming on his lips as he glances at you with sparkles in his eyes.

Oh, that damn smile.

And without meaning to, you join in his laughter, covering your mouth with your palm so as not to be heard as, for the first time in weeks, a weight is lifted from your shoulders. The little analogy that might have irritated you a few days ago seems silly to you. Why do it when he’s here?

The bell rings, announcing the end of class, and the hubbub of the students urges you to put your things away as much as possible before the teacher gives you more homework than you already have just to understand the lecture.

With your bag slung over your shoulder, you make your way towards the exit, at the end of the herd of students who have made you lose sight of Satoru. A little disappointment contracts your heart, but after all, why should he be waiting for you? There was no need. You’re not friends. Just two students who are nice to each other (well, mostly Satoru).

So as you walk out of the lecture hall, you almost come face to face with a 6’3. Your nose collides painfully with a hard, bumpy surface — wait, of abs?

Impossible.

A hand much larger than yours wraps around your elbow to steady you and meets your eyes down on your wincing face.

“Oops, sorry,” Satoru apologizes as his smile evaporates. “Are you okay? I just wanted to wait for you.”

Was it abs?

“No worries, I'm fine,” you assure with a smile as self-conscious as it is forced, one hand rubbing your sore nose. “That's sweet.” Then you look away to calm the blush that spreads like a puddle from your neck to your scalp and pray it's unseen.

“You sure?” he insists with a concerned frown.

“...Sure.”

Once your face has cooled, your eyes stare at the spot on his torso where your nose collided. That flat spot under the shirt that appears a little less to you now, seen up close. It's as if with every swell of his breath, you can see the beginnings of an abdominal bulge, but you shake your head to get this far-fetched idea out of your head.

Letting your hand fall back, you offer him a more confident smile and lead the way. “Shall we?”

With a slower nod, he follows you.

To bridge the silence between the two of you in the deserted corridors, you nudge him in the ribs and say, “You know, I still don’t get how you find physics fun.”

He feigns pain and smirks — does he only smile when he’s with you?

“I don’t find it fun, strictly speaking, but really very interesting. At least, enough to make me face my major.” He pauses to give you a teasing look. “And I still don’t get how you survive on four hours of sleep.”

“I am a vampire,” you grin stupidly, “I love working at night. I feel productive.”

“I see that. Your bags speak for you,” he chortles.

“For real?” you mouth, running your fingers over your dark circles as if to check his words when it makes more sense to look in the mirror rather than feel you up.

“Just joking,” he murmurs, dropping his gaze on the floor a second before looking up back at you. “But you seem very stressed lately, am I wrong?”

You don’t answer right away, reluctant to tell him about your doubts and what’s been bothering you for weeks. But you can. This is just two friends from the same quantum physics class strolling around campus at the end of a long day, isn’t it?

But maybe not close enough for him to be really interested in you? Maybe he’s just asking questions out of politeness and not out of any real concern for you. After all, you’re not really close.

“It's alright, just uni and student council stuff, as always,” you murmur with averted eyes. “We also need to plan our next tutoring session.”

“Yeah...” Satoru shoves his hands in his pockets and lets silence fill the gap between the two of you before resuming. “Maybe we could do it somewhere else this time, couldn’t we?” he offers without much hope in his voice.

You knit your brows. “What?”

“I mean... do you—uh, never mind.”

You raise an eyebrow. “Huh?”

He seems to chicken out and look away but you catch it before he could hide it — the tips of his ears are red.

“Nothing. Just... you’re really into this whole Spring Formal thing, huh?” he mumbles.

“Of course. I have a lot of work to do on it. But what were you asking me?” you insist with a softer tone and your hand wrapping around his arm — remarkably built, you note internally.

He finally twists his neck toward you to face you, lips pursed into a conflicted pout.

“You’re going to refuse.”

“You didn’t even try to ask,” you almost in a mid gasp and chuckle.

He runs a hand through his tousled snowy hair, then slips it around the back of his neck, rubbing it like a nervous tic. “I see that you’re stressed — even if you deny it. So would you accept to... maybe do work on our tutoring lessons in a better place?” He panics slightly under your unfathomable gaze, just waiting for the next part of his words. “I mean... I know a place where it could be less stressful and more relaxing because you deserve it... But of course,” he adds hastily, “it doesn’t commit you to anything and you don’t have to accept and we can totally carry on doing it at the library because really it’s just a stupid idea and I should just keep my mouth shut—”

“Satoru.”

His heart stops beating and he thinks his brain has short-circuited as he realizes it’s the first time you've said his first name in that tone.

Softly, reassuringly, and with obvious joy.

“Of course I’d like to work with you somewhere else. It means a lot to me that you thought of me like that,” you say softly as you stop in front of some stairs so you can look him straight in the eye. “I can give you my phone number and you’ll just have to send me the address, how’s that?”

Okay. His brain really has just short-circuited.

He doesn’t even remember how he managed to hand you his phone and record your number, wish you a good evening and return to his dormitory after being subjected to your beaming smile — of a particular radiance he’s never seen before on your face in all the time, however long, he’s spent gazing at you wherever you are — radiant even.

Lying on his bed, he stares at the ceiling. The silent night allows his thoughts to grow louder, as if several were trying to express themselves at once.

However, one image takes root in his eyelids when he closes them before sleeping.

You.

~~~~

“You shouldn’t have.”

“Do you really need to make this even more embarrassing?”

You shake your head. “It’s not fair.”

His features sag, and he lets out a tiny sigh. “Just please, accept it. I made it for you.”

At your feet lies a picnic blanket with red and white checkered patterns. On top of it are homemade sandwiches, cans of fruit juice, berries, cakes, and even a tub of ice cream resting inside a mini cooler. Satoru has even arranged the space to avoid a chaotic mess while working and has brought ultra-comfortable cushions to make the tutoring session as pleasant as possible.

He can’t do this.

Not with you, who arrived at the quiet, sparsely crowded city park, right under the most magnificent Japanese cherry blossom tree.

The cool breeze blows gently around you both, sweeping away a few strands of your hair that you’re forced to tuck behind your ears.

“Sit your ass down,” Satoru mumbles, looking away to hide an obvious embarrassment, though his hand pats the empty space he left just for you.

So, reluctantly, you sit cross-legged, grabbing a random sandwich — just so he won’t sulk — and try not to cry because it’s so ridiculously delicious. The berries couldn’t be fresher or juicier than any you’ve ever tasted, and not to mention the cakes he brought. The majority of the food is sweet — his sweet tooth showing up a little too obviously.

“Hope it tastes good,” he adds, his lips forming a slight pout.

“Never ate something that good,” you respond, mouth full of food. “You’re an angel.”

The word makes him freeze for a solid thirty seconds before he shakes his head and lets his gaze drift away — always avoiding — toward the nearby lake.

The ground is sprinkled with pale pink petals, blending into the vibrant green grass of this March afternoon. A few birds chirp in the distance, hardly anyone comes near your secluded spot, and the peaceful silence reigning over the park creates the perfect environment for getting work done.

Swallowing his own mochi, Satoru watches you take out your notes on the latest physics chapter, and instead of sitting across from you, he allows himself to settle beside you this time — without you pulling away.

He was hesitant from the start and may never be able to stop feeling nervous around you. No matter how often he’s around you or how much more familiar he grows with your presence, he can’t control those sudden spikes of nervousness that hit when he’s already comfortable — only for one small action or movement to give his poor little heart a crisis.

You hand him the exercises you worked on last night, and while he reviews them, you take out your planner and notepad — the ones you carry everywhere (even to bed and the bathroom)—to go over the organization of the upcoming Spring Formal.

An event that’s happening soon. An event with absolutely nothing planned yet.

You quietly jot down notes on possible themes, but after another glance at the endless, sprawling branches of the massive cherry tree, you sigh and toss your notepad aside onto the picnic blanket. No ideas in sight. You have no choice but to admit your incompetence. Your failure is inevitable.

“Here.” Satoru hands you back your corrected exercises, and you quickly scan through them.

Since the beginning of your sessions with him, you have to admit — you’ve improved.

This time, there are fewer scribbles and corrections from Satoru. Your formulas and applications are more precise, clearer, and better developed. All thanks to your hard work and Satoru’s expert guidance — the science genius himself.

There are still some non-negligible mistakes to fix, but at least the encouraging smile from your tutor warms your chest, silently telling you that you’re on the right track.

“This is really not bad,” he murmurs softly near your shoulder. “You’re seriously improving.”

“Thanks to my good tutor,” you reply, nudging him playfully with your elbow.

“What flattery. I don’t deserve this much.” Yet his so-called humility is betrayed by the deep red blush dusting his ears.

“Quite the opposite. I wish I could pay you back somehow.”

“You don’t need to. I told you it was my pleasure to help you.”

“And I feel bad about it,” you confess in a whisper.

“Don’t,” he insists — and dares to wrap his slightly trembling, warm hand over yours on the blanket.

Your heart flutters, like a butterfly trying to take flight, only to be tossed around by the wind.

“Thank you,” you whisper, with more honesty than you’ve ever given anyone.

“For being a good friend? Don’t worry, I’m glad to have you as well, honestly,” he murmurs back, punctuating his words with a light squeeze of your hand.

“And I—” he clears his throat, “...really appreciate you.”

Friends. Appreciate you.

“I appreciate you too. Really. I’m sorry if I mess up every move you try with me to help me,” you add with an apologetic smile. “Stress always ruins my life.”

“I told you that you couldn't deny it.” He raises his eyebrows and lift up an uncertain arm — seeing you not reacting has reassured him enough to pluck up the courage to pass it around you to console you. “Tell me what’s wrong.”

You let yourself go against him, burying half your face against him. “I’m in deep shit about organizing the Spring Formal. I haven’t prepared anything, I have no idea, and yet I’ve got plenty to do. Mr. Yaga warned me that he might replace me if I went on like this, and I feel like everything’s going to shit,” you say in a breath, a tiny barrier of vulnerability cracking.

His arm tightens in an attempt at comfort. He nods slowly, inhaling long breaths of fresh air before making a clicking sound with his tongue.

“Where’s your notepad?”

You hand it to him without protest, and he immediately grabs it and flips through it. Then, when he finds a blank page, he grabs a pen lying near the two of you and jots down a few sentences, the words of which you can only read when he hands you the notebook.

“An alignment of the planets?” You raise a curious, surprised eyebrow.

He nods with his chin and sketches a smile.

“It only happens in spring, practically. And there will be one before long.” He squeezes his arm around you again and chuckles. “A theme about planets might be nice, don’t you think?”

Lips parted, you gaze into the azure sky. Himself a little disarmed by your lack of reaction, he frowns without giving up his smile and softly pronounces your first name.

With zero control over your movements, there’s nothing to stop your lips from pressing tenderly against Satoru’s smooth, soft cheek — a firm but gentle kiss leaving an invisible, indelible trace on his radiant skin as you pull away to look into his eyes again.

“You're an angel,” you repeat a second time.

Well, the second time too, when Satoru’s heart, no longer knowing how to beat, simply stops beating.

~~~~

“Move them a little more to the right— Yes, that’s perfect.”

Your trusty notepad clutched against your chest, you admire the preparations unfolding in the venue for the upcoming Spring Formal, where the theme of planetary alignment is set to make this year’s university event truly unforgettable.

Finally, you’re no longer spending your time yelling at your team and barking orders fueled by the vibrant sparks of your stress. Instead, you’re giving clear instructions, each one accompanied by an encouraging smile for everyone.

“Maybe we could add midnight blue velvet curtains,” Satoru suggests, leaning over your shoulder, his chest brushing pleasantly against your back as he glances at the list of missing decoration orders. “We could stick fake stars on them, and it’ll draw more attention to the planets. What do you think?”

“I like the idea,” you giggle, despite the way your insides somersault when his warm breath grazes your ear, sending waves of goosebumps down your skin. You jot down a few notes as Satoru leans in even closer, gently resting his chin on your shoulder. “Not surprising, coming from the quantum physics genius of the entire university.”

Even though there’s nothing official between you — not if you ignore the feelings and trust that make Satoru more confident and relaxed in your presence — nor any concrete relationship, the warm intimacy settling between you two is anything but uncomfortable.

It’s like a mutual friendship, fully acknowledged by both of you, yet intertwined with threads of love left unspoken — often betrayed by moments of closeness like this one.

“You’re gonna make me blush again,” he admits with a light laugh, soft and delicate as a cherry blossom petal.

“Oh yeah?” You turn your head toward his — just enough for your faces to be so close that the tips of your noses brush. “Why?”

He sighs, fluttering his eyes closed for a brief moment before opening them again. “You know why…”

“I’m clueless when it comes to guessing thoughts, my hot nerd tutor,” you coo, a little grin spreading across your lips — those same lips he wanted to kiss until he couldn’t breathe anymore for the rest of his life.

“Maybe I could show you, then.” And gently, he places his hands around your waist, an easy, soothing smile on his face. “Is that okay if I do that?” After your nod, his smile grows even wider. “Also, could we do our next session at my place? I can’t stay at the library today because my mom is waiting for a package while she’s at work, so she asked me to take care of it.”

“Of course.” You take note of his suggestion while the rest of your team rushes to decorate the room and move boxes — some opened, some not. Then, you turn back to him, feeling the slight tremor of his hands against your body, the way the blood rushes alarmingly fast to his face, and how his eyes avoid yours.

“Blushing?” you giggle.

“You’re not embarrassed? I mean— It’s my place, not my dorm or the library, you know,” he mumbles.

You graze a kiss on his soft cheek and grin. “You’re freaking cute.”

“I’m not joking,” he whines lowly, a small, worried furrow forming between his brows.

“As am I.” You give his arm a little squeeze. “Everything’s gonna be alright. I don’t mind having you all alone in your house, though.”

And you burst into laughter when he chokes on his own saliva at your words — having never seen someone turn so red before.

~~~~

“I knew you liked physics, but not that much.”

Before coming to set foot in Satoru’s room for the first time, you expected to be dealing with a simple, uncluttered, organized room, and above all far more filled with bookcases overflowing with books rather than...

...the opposite.

Stepping into Satoru’s room feels like entering a nerdy galaxy of controlled chaos. His desk is cluttered with thick physics textbooks, some stacked neatly, others left open mid-read, pages filled with complex equations you can’t even begin to understand. Among them, a few manga volumes peek out, half-hidden like a guilty pleasure. Above, a whiteboard covered in messy formulas and doodles dominates the wall, the marker strokes chaotic but somehow full of purpose. His ceiling is scattered with glow-in-the-dark stars, forming actual constellations if you look closely, and a floating moon lamp sat on his nightstand, casting a soft glow over his unmade bed.

Everywhere you turn, there is something to mess with — a plasma ball that lit up at your touch, a Newton’s Cradle clicking rhythmically on his desk, even a weird futuristic clock displaying time in some incomprehensible format. His monitors hum with life, one running a sci-fi screensaver while another had what looks like a physics simulation he’d probably forgotten about.

And yet, despite the overwhelming nerd energy, it was… comfortable. Lived-in. A place where ideas sparked and theories came to life — exactly what you could imagine his space would be if you’d thought things through a bit more.

“Wow,” you murmur, entranced. “It’s… just beautiful. Like a museum.”

“Heh? You’re flattering me really too much,” he chuckles nervously, scratching his neck where his undercut is. “But I’m glad if you like it. I want you to feel home,” he adds softly.

“Home?” You turn to him with a slightly embarrassed and moved smile. “You’re my home, actually.”

Nothing you say makes sense. Your racing heart lets your mouth babble nonsense and scare Satoru away. You’re far too embarrassing—

“I feel the same for you.”

Like a needle piercing a balloon, your vital organ explodes in your chest.

The next second, your brain regains control and orders your legs to move towards him, until your torsos brush against each other and your breaths mingle, giving birth to a gentle flame that burns only to be consumed.

Satoru whispers your name. “Can I try something?” he mouths.

You nod imperceptibly, your gaze lost in his ocean eyes.

Tenderly and with the most delicate gentleness, he cups your cheeks, tilting your head so that your face faces directly forehead to his. So close, you have a detailed view of the number of his light eyelashes, the different shades of blue mingling in his irises, the pleasant warmth of his tepid breath against you.

Then, his lips brush yours first, as if testing your reaction. But when your fingers latch onto his light-brown V-neck sweater, he feels the pressure rise in his blood and slowly, but suddenly, crushes his lips against yours.

It’s not rushed — just a soft press of lips, tentative, almost careful. As if he's afraid of breaking something fragile. So to encourage him, you sigh softly in contentment, then tilt your head the slightest bit to fit better, closer... Your hands remain gently clasped to his sweater.

He seems to get your message, because the next thing you know, he’s relaxing, moving more slowly and comfortably against yours. The world outside that moment doesn’t exist. Just him, just this — his lips, softer than you expected, the careful way he kisses you, as if he is memorizing every second of it. Time stretches thin, and even when you finally pull apart, neither of you move far.

Slowly, you open your eyes, only to find him already looking at you. His gaze is different now — quieter, warmer, like he is seeing you in a way he never had before.

For a moment, neither of you speak. The silence is soft, not awkward, filled with a kind of understanding that doesn’t need words. And then, just barely above a whisper, Satoru exhales a quiet, shaky laugh.

“Oh.”

Just that — like he hasn’t expected this, like he’s still processing the fact that it happened at all. And maybe it’s the way he looks at you, stunned and a little breathless, or maybe it’s just the warmth still lingering between you, but you find yourself smiling, a tiny, barely-there curve of your lips.

“Yeah,” you murmur back, voice quieter and warmer than you intended.

Neither of you moved away. Not yet.

You lower your head, a hot flush creeping up your cheeks and neck, and that's when you also understand where his “oh” is coming from.

Oh.

While he turns away to hide his face in his hands and prays to be buried in a grave on the spot, you burst out laughing — a frank, non-judgmental laugh. Simply savoring this pleasant moment with him (albeit with one small problem).

“Just with a kiss? Satoru, I swear you’re the cutest!” you continue to laugh, half-folding with your arms hugging your belly.

“It’s not f-funny!” And the poor guy doesn’t even dare turn around as he adjusts his pants, which is where his “problem” lies.

Smiling, you move closer to him, your lips still prickling from the perfect kiss. One of your hands slips to his shoulder and gives it a gentle squeeze. “It’s okay.”

“It’s not,” he mumbles, hiding his face again from your sight.

“It is,” you insist, wrapping your hand around his wrist to look at him. “I’m not judging you, I swear. It’s not like you can control that, is it?”

“I know, but— It’s so embarrassing. I feel like a poor virgin nerd that — well, It’s not like I am not but—”

You freeze, slowly losing your smile. “Wait… you’re a virgin?”

He nods, a little shameful pout creasing his lips.

“I—” you trail off. Taking a short breath, you lower yourself a little more to look at him as he covers his crotch with one hand. “I can help you with that, you know.”

His eyes widen, heart hammering in his rib cage. “W-What?”

An umpteenth laugh shakes your chest. “I mean, yeah. I don’t mind and I like you.” Then an idea pops into your head, like a lamp regaining its light. “Like, it would make up for the effort you put into helping me get good grades. What do you think?”

He straightens abruptly and gently but firmly pushes your hand away by the wrist. A serious look despite his embrace adds.

“No way. I already told you I don’t want anything in return.”

“But it’s just to please you,” you insist, flickering your eyes. “Don’t you want to know how it feels?” You take a few steps forward until you can wrap your arms around his perfect torso — the ideal balance of slim and muscular.

Your chin rests on his breastbone, a little imploring pout on your lips.

“C’mon, just an oral, I promise. I want to return the favor.”

He swallows hard, lips parted as if the words are stuck somewhere between embarrassment and want. His gaze flickers between your face and the floor, a mix of reluctance and curiosity in his eyes.

“But I—” His voice cracks slightly, a nervous laugh escaping him. “I don’t know what I’m doing…”

You smile, a quiet, knowing smile, and slide your fingers slowly down his arm, your touch lingering on his skin. “It’s okay,” you say, your breath barely above a whisper. “I’ll guide you.”

You can see him shiver at the words, his chest rising and falling rapidly. You take your time, moving in closer, making sure to leave no space between you. Your lips brush against his jaw, a delicate kiss that makes his entire body stiffen for a split second. He doesn’t pull away, though, and that’s enough to encourage you to go further.

“Just relax,” you tease, pulling back slightly to look up at him. “I promise I’m not going to bite.”

“I know, I just need to sit a bit,” he whispers, a wave of uncertainty in his eyes.

You pull away from him, feeling the palpable tension between the two of you. “Of course.” You take his hand in yours and guide him onto his bed. When he sits down on the mattress, you find yourself kneeling between his legs.

As your hands busily unzip his straight gray twill pants, you maintain eye contact. “Tell me if it’s too much or if you wanna stop, okay love?”

Love.

He nods gently, his elbows pressed into the softness of the mattress to get a view of your movements without him lying down completely. Lips trembling, Satoru feels obliged to bite them to calm himself as the heat almost suffocates him while all he has left is his boxer shorts hiding his growing erection under the thin fabric.

You can feel the air thickening between you, charged with the kind of quiet intensity that makes your pulse race. Your fingertips wrap around the waistband of his boxers and tug them down gently, letting the fabric rub against his length while he’s hissing.

“Sweetheart—”

“Relax, I’m just getting started,” you chuckle fondly.

When the underwear is pulled down, his erection springs free, slamming on his half-covered abdomen. The poor little thing, left alone, twitches painfully — dragging sounds like cute and innocent whimpers from Satoru — like it’s begging for your touch for a decade.

You curl your lips together, genuinely stunned by his size. 7 inches isn’t nothing.

“So you’re packing this from the start?”

“I— No…” He sighs, clenching his jaw as his eyes flutter closed. “Please, it’s already embarrassing.”

“But why? You’re beautiful, Satoru. And I’m not talking about your dick,” you snort. Your gentle, affectionate tone makes Satoru forget how to breathe and open his eyes again. “You’re beautiful on the inside too.”

“You’re only flattering—”

“I am not,” you state firmly, getting up from your knees to straddle his hips and cup his cheeks until they puff like mochi’s and he’s pouting.

Fucking adorable.

“Have you ever been into a relationship?” you whisper after pecking a kiss on the corner of his lips.

He shakes his head, stuttering a no.

“So can I call you mine? Because I’d be yours if I could,” you mutter next to his jaw where you peck another kiss that makes him shiver and grip your hips with his hands.

He opens his mouth to say something and hesitates. “A-Are you sure?” he asks, eyes filled with doubt. ‘I’m a nerd and—”

“And my type is nerd guys,” you cut him off before pulling him into a passionate kiss. He gasps, tightening his grip on your as his lips gently taste your and steal his breath away. “I love you, Satoru.”

“Love you more. Since the first time I laid my eyes on you,” he murmurs back between kisses, eyelids shut.

You slightly pull away, a smile springing to your lips. “Pinning on me for so long? Aw, sorry to have been blind for this long too, then.”

He resists the urge to take you in his arms and lets you back down onto your knees, this time with his oversensitive cock throbbing in your hands as you begin to stroke it up and down, base to tip with all the slowness you can manage so as not to make him cum too quickly.

Satoru’s hips jerk up instantly, his chest rising and lowering because of his stuttering breath.

“Your hands feel so good and soft,” he whispers, sliding his big hands up to your shoulders, which he gently massages to relax you too. What a gentleman. “So much better than mine…”

“Yeah? You like it?” Eager to please him for his first time, you place a kiss on his angry red tip, licking a little strop with the tip of your own tongue.

“Hgn— easy,” he pants, hands shaking slightly as they interrupt their massages on your shoulders when yours lead them on your head, tangled with your locks. “What are you—”

“You can use my hair, if you want.” And you punctuate your words by taking his length back between your hands and kiss the fat head. It twitches in response, stealing little giggles from your sweet lips. Beads of precum leak along his length, helping you to wet him enough to stroke him faster as you part your lips and slide them down the length of him.

Satoru’s breath hitches when you take him, sucking in slow, deep strokes as your hand grips the base of him. You pull back slightly, your lips sliding back up, and you hear him groan, a sound that makes you ache. You repeat the motion, taking him deeper, sucking harder as you run your tongue along the underside of his cock, feeling him twitch in your mouth before you pull back again.

“Feel good?” you ask sweetly.

“You’re perfect,” he breathes out — even whimpering in neediness, “thank you so much…” His hands tighten in your hair, pulling you even closer, but it’s not enough.

You don’t stop. Instead, you take him deeper, your lips tightening around him as you move faster, the sound of your mouth on his cock filling the room, drowning out everything else. Satoru’s breath grows shallow, irregular, his body starting to tense, his legs flexing as he tries to hold back.

But you can feel it. The way he is so close, the way his body is winding tighter with every flick of your tongue. His fingers pulled at your hair, unsure to guide you just how he wants because what you were doing is already something he’ll owe you all his entire life — he is desperate, needing his release.

“F-Fuck,” he stutters, fingers digging in your scalp deliciously for you pleasure. “I love you, but please, g’nna—”

“—cum? Yeah, do it, love,” you purr affectionately as you teasingly suck his sensitive tip until he’s whining and fighting for his hips to not thrust up and hurt you.

He is there — at the edge — his cock twitching in your mouth, and you know he can’t hold on much longer. With one last deep, slow pull, he cums, his hips jerking as he releases into your mouth with a long, desperate groan. You swallow every drop, sucking him clean, your hands gently massaging his thighs as he slowly comes down from the high.

Satoru’s breath is ragged, his body shuddering as he slowly opens his eyes. He looks at you like you’re some sort of angel from heaven, and you smile, wiping the corner of your mouth before standing up.

“Feel better?” you ask teasingly, your voice light despite the heat still pooling in your stomach.

He sighs deeply, rubbing his eyes before carefully sitting up and hugs you in a tight embrace. He blows kisses all over your face, murmuring thank yous and how much he loves you and you find yourself in awe.

“You’re welcome, it’s the least that I can do for you, after all.” You press a big, firm, and sincere kiss on his cheek, and cannot stop smiling.

~~~~

The main room is bathed in a deep blue, soft, ambient light, the atmosphere almost otherworldly. Stars shimmer faintly on the walls, and delicate, hanging lanterns cast a stunning cold glow, like constellations scattered across the ceiling. The whole room seems alive, breathing with energy, as guests drift through the space, their laughter and chatter blending into a gentle hum.

At the center of the hall are huge telescopes, available for anyone curious enough to observe tonight’s planet alignment. The most important event of the Spring Formal.

Around the perimeter, tables are set with shimmering candles, their flames flickering softly, casting shadows on the faces of the students who’ve come to admire the setup. The smell of roses and lavender lingers in the air, mixing with the faint scent of freshly baked treats at the snack table. It feels like a dream — a celebration of the night sky brought to life.

Satoru stands beside you, his hand lightly brushing against yours as you both take in the beauty of the room. His smile is small but warm, his gaze drifting from the decorations to the crowd. There’s an unspoken pride in the way he looks at you, knowing you had a hand in making all of this happen, bringing the theme of the planets to life with such care.

“This is... perfect,” he says, voice soft but full of admiration. His words are simple, but they carry weight. You feel a soft warmth settle in your chest at the sincerity in his tone.

A small smile blooms on your lips. “Yeah…” you agree, turning to face him fully, now a grin spreading across your face. “It really turned out great. Thanks to you.”

His cheeks tint pink at the praise, and he shrugs, trying to act nonchalant, but the pride in his eyes is unmistakable.

“You really made this all come together,” he says, voice full of admiration. “It’s amazing.”

For a moment, you simply smile at each other, a comfortable silence settling between you. The warmth of his gaze makes your heart flutter in your chest.

“Want to dance?” you ask, already knowing his answer, but wanting to ask all the same.

He hesitates for a moment, that same shy, unsure side of him creeping back, but the smile on his lips says everything.

“Yeah,” he says, his hand finding yours once again, this time with more confidence. “I’d love to.”

As you both step onto the dance floor, the lights change again, and for a moment, the two of you are surrounded by the glow of the stars and lanterns, your bodies moving to the soft music that fills the room. It’s not a fast, frantic dance — just slow and gentle, like you’re in your own little world. You feel the gentle sway of the music, and the weight of everything around you fades, leaving just the two of you in perfect harmony.

Maybe it’s the magic of the planets aligning, or maybe it’s just him — but either way, you think, you wouldn’t mind orbiting around Gojo Satoru a little longer.

a/n: there we go! I AM DRAINED BC OF SCHOOL AND COURSES GUIDANCE BC LAW IS SO HARDDDD!! hum hum, beside that, i hope you guys had a nice week and that you are all taking care of your little faces (if not i'm gonna do it for you). writing this felt like... refreshing? i mean, nerdjo is the little mochi i'm eating when i go to the supermarket lol. and gosh, he's so cute that i'm going crazy haha.
