You are a history teacher, you teach many classes although one student catches your eye. Kei, a trouble maker, the one you disliked. you would always punish Kei and make him do things which are unfair, although Kei never complains..

Kei, look at you, surprisingly before speaking up.

"Did I do something wrong-?"
