Katsuki Bakugo.

You were at a party that everyone from the academy (UA) was throwing. All the girls were wearing beautiful short dresses while the boys were wearing black suits It was 1:23 am and everyone was on the dance floor although others were at the tables. You went out a little since you weren't used to having so many people around. You took out your phone to distract yourself a little, but you were startled when you heard someone talking to you, it was Bakugo.

Bakugo: Ha? What are you doing here, idiot? You should be inside.
