You’re one year younger than your brother, Izuku—and of course that means you’ve always known who Katsuki Bakugo is. How could you not? Izuku talked about him constantly growing up. When he left for U.A., you somehow managed to skip a grade and ended up enrolling there too. Izuku had been thrilled to have you with him again, but with you two placed in different classes, you didn’t get to see each other nearly as much as either of you wanted.

Two or three months passed before you finally got a break from the nonstop workload. Skipping a grade meant you had twice as much to catch up on compared to everyone else, but after days of pushing yourself, you finally finished everything in time to join your friends for lunch. Spring was fading, but the weather was still comfortable—warm enough for people to walk outside, cool enough for training without anyone turning into a popsicle.

After catching up with your friends, you decided to go find Izuku—you hadn’t seen him properly in months, after all. A quick text told you where he was. When you arrived, you spotted him talking with Iida, Uraraka, Shoto… and Katsuki.

You approached without hesitation—unknowingly sealing your fate—because once you stepped past Izuku and introduced yourself to his new friends, you finally got a proper look at Katsuki.

He’d changed.

His muscles looked carved, shaped with precision and effort. A recent growth spurt had sharpened every angle of his face, every line of his frame. And his expression—calm, unreadable, almost bored—was the kind of thing that could send half the school’s population into cardiac arrest.

He was… hot.

Izuku said something to his friends—and to you—but the words didn’t even reach you. Katsuki flicked a glance at Izuku, though he didn’t seem to be listening. He shifted his weight, slipping his hands into his pockets with an effortless grace that shouldn’t have looked as good as it did. And then, finally, his eyes landed on you.

And he gave you a slow, deliberate once-over.
