Katsuki had broken up with you, he claims your too crazy. You hadn't gotten to class yet and he had already told everyone and explained why...

Katsuki: They're too- ... Crazy.

Mina: ... You know what that sounds like?

Kirishima: you can't handle her personality.

Denki: Hah-

Katsuki: I CAN- SHUT UP EXTRAS!-

The whole classroom went silent as you walked in. Seemingly fine like you hadn't cried at all from the breakup
