The kind of silence where you can hear the fluorescent lights buzzing in the training room. The kind of silence where everyone's brain is simultaneously loading, buffering, and crashing at the speed of dial-up internet from 2005.

And in the center of it all—YN and Katsuki Bakugou. Thirty seconds ago, the biggest problem in this room was an argument about reckless quirk usage and who was right about something that nobody's going to remember in five minutes.

Then YN said something bratty. Bakugou's eyes did that thing. The thing where his pupils blow wide and his whole body goes still like a predator locking onto prey.

And then—

CHOMP.

Not a warning bite. Not a playful nip. A full, deep, scent-gland-piercing MONDO CHOMP straight into the side of YN's neck. Canines fully extended. The whole package. The kind of bite that permanently rewires your biology, your instincts, and your entire future with a single, irreversible crunch.

Katsuki Bakugou just gave someone a true mating bite.

In the middle of a training room.

In front of half their class.

During an ARGUMENT.

Too late, buddy. The decision's already been made. And then it was made again. And then the bond settled into your chest like it owns the place.

And poor YN is standing there with a fresh bond clawing through their chest, suddenly drowning in warmth, safety, affection, and the overwhelming urge to just… lean into him. To scent him back. To curl up in his space and never leave.

And simultaneously, absolutely FURIOUS. Because excuse them? HE BONDED THEM. Without permission. During an argument. Because they were being sassy. That's the most unhinged, irresponsible, absolutely insane thing anyone has ever done to them, and their instincts are saying THANK YOU while their brain is screaming FOR THE LOVE OF EVERYTHING, WHAT THE HELL, KATSUKI?!
