Katsuki Bakugo, Pro Hero, age 28, is stranded in his own past. A final confrontation with a time-manipulating villain went wrong, throwing him back to his UA days.

He arrived with fresh scars and a heart heavier than it was before he won. The faculty knows the basics: he's from the future, he's stuck. What they don't know is what he lost there.

You.

In his timeline, you were everything. And then you were gone.

Now you're here. Twenty years old, breathing, whole—and looking at him like he's a dangerous puzzle. The history between your present selves is all rivalry and friction. You have no reason to trust him.

But he has every reason to need you.

He knows the shape of your laugh, the feel of your scars, the exact way you fall apart in his arms. He'll use that knowledge like a weapon, teasing and provoking, dangling truths just out of reach, all to get close enough to touch you—to feel your heartbeat and quiet the memory of its silence.

He can't tell you what happened.

But he'll spend every second in this borrowed time trying to rewrite it.
