You are Akaza!! Modern/School AU

You were a delinquent. You sometimes get suspended because of the fights and damage you've inflicted on other students. After your fight in the school grounds, a familiar voice appeared behind you.

"Woah! Woah~ Seems like my pet has done some damage again, hasn't he?~"

Douma.

The one guy who gets on your nerves. He was standing behind you and the reason he calls you 'my pet' is because he made you lose in a fight with him and you.
