Chapter Text
Satoru Gojo never corrects the professor.
He doesn’t need to.
He sits in the back of the lecture hall, long legs tucked neatly beneath the desk, glasses low on his nose, pen moving with unhurried confidence. When the professor glosses over a key step, Satoru’s pen pauses...just for a moment, before he writes the correction in the margin, precise and elegant, like the mistake never deserved more than that.
You notice because you’re close enough to see it.
You shouldn’t be, really. You usually sit closer to the front. But today you’d arrived late, and the empty seat beside him felt… deliberate, somehow. Like it had been waiting.
Satoru doesn’t look at you.
Not at first.
He drops his notebook five minutes before the lecture ends.
The sound is sharp in the quiet room, pages skidding across the floor. A few people glance over. Satoru exhales softly, more resigned than embarrassed, and reaches down just as you do. “Careful,” he murmurs.
You pause. “What?”
“That page,” he says calmly, fingers hovering just above yours. “It goes back after the theorem.”
You blink, then hand it to him. “You noticed fast.”
He hums, amused. “I tend to.” For the first time, he looks at you properly. There’s something unsettling about his gaze...not intense, not rude. Just… thorough. Like he’s cataloguing you, filing you away for later. “You were following the lecture,” he says. It’s not a question.
“I—yeah.”
A faint smile curves his mouth. “Good.”
The library is where he approaches you. Not hesitantly. Not nervously. Just… quietly certain. “You don’t mind if I sit here,” he says, already setting his books down across from you.
You hesitate. “I was kind of—”
“Studying?” He tilts his head, eyes flicking over your open notebook. “You’re stuck.”
Your stomach flips. “You don’t know that.”
He taps the margin of your page with his pen. “You circled the wrong variable.”
You stare at it. He’s right.
“I can explain,” he adds, softer now. “If you want.”
You nod before you can think better of it.
He leans in, not close enough to touch, but close enough that you’re suddenly very aware of your breathing. His voice is low, measured, patient in a way that feels intentional. He walks you through it step by step, pausing whenever you hesitate, waiting until you nod before continuing.
When you finally get it, really get it, his lips curve upward.
“See?” he murmurs. “You’re smarter than you think.”
The praise lands heavier than it should.
He watches your reaction. You’re sure of it.
Studying together becomes a pattern. Satoru never asks. He just… shows up. Same table. Same time. He always remembers what you struggled with last session. Always brings the exact book you need before you ask for it. Sometimes, when you answer correctly, he nods once, satisfied. “Good,” he says quietly. “I knew you’d catch on.” Sometimes, when you don’t, he doesn’t get frustrated. He just repeats himself, slower, until you do.
“You like understanding things,” he tells you one evening. “Not just memorizing.”
You laugh. “Is that a bad thing?”
“No.” His eyes flick up to yours. “It’s rare.”
You catch him watching you when you’re not speaking—gaze lingering a beat too long, expression unreadable. When you look back, he doesn’t look away.
He smiles instead.
One night, as you pack up, you notice annotations in your notebook that weren’t there before, clean handwriting in the margins, correcting your work, guiding your steps.
“You did this?” you ask.
Gojo adjusts his glasses. “You left it open.”
“You didn’t have to.”
“I wanted to.” A pause. “You don’t mind, do you?”
You swallow. “No.”
“Good,” he says again, softer this time. “I’d hate to stop.”
As you leave the library, you get the strange, persistent feeling that Satoru Gojo knows you better than he should. And worse, that he’s very pleased about it.
