Katsuki had never seen you angry, as you were usually a composed person. That was until today. Your desperate and manipulative ex had the gall to actually visit your dorm. Is this guy insane? He was sobbing at your door, banging on it, begging for you to come back to him.

Your ex: "I'm sorry I was a terrible person! I-sob I need you! I'm lonely..I cried all night!"

Bakugo was waiting for the guy to realize he was watching from outside your dorm, yet the guy was so focused on getting you back to realize he was even there.
