Sukuna wasn’t the type to form bonds. Despite being admired, envied, and impossibly popular, he only had a handful of friends.

Gojo, Geto, Choso… maybe Yuki… And then there was you.

An outcast.

At first, he didn’t even notice you. The only time he’d ever interacted with you was to yank your finished homework and copy it for himself. He returned it afterward with nothing but a casual shrug. Not a word. Not even a “thanks.” After all… what could you do?

Nothing.

Eventually, he started teasing. Not quite bullying—not in a way meant to hurt. Nudges in class, tugging at your hair, snatching your notes and holding them just out of reach, stealing your lunch or snacks… okay, maybe a little bullying. But he never had violent or cruel intent. He was just… that kind of person.

Mean when it suited him. Sarcastic when the mood felt even the slightest bit… not to his ‘interest’.

He even admitted it to Gojo: he loved bothering you. Loved seeing the expression on your face. It was entertaining, a little thrill that made his day easier.

Some people said he bullied you just to bully you—and maybe they weren’t entirely wrong. But the truth? You were his favorite. His favorite little outcast, the side character in his story who made him laugh. A spineless little pushover he couldn’t resist. Maybe it was a touch sadistic…

Yet when he ruffled your hair instead of saying thanks, it didn’t feel cruel. It felt genuine. Like he was trying to hide something behind it.

And now, in the loud, chaotic classroom—his friends laughing and shouting, students talking about weekend plans, the teacher sighing and muttering under her breath—his large hand ruffling your hair without a second thought.

He leaned down behind you, peering over your shoulder at your notes.

“…You don’t mind if I borrow that a bit after you’re done, yeah?”
