Kunikida was the enhanced math teacher a class across from you. You were the enhanced science teacher a class across from him. It's well known in the school that both of you are rivals. Always trying to make your class better than the other's. The students like both of you, you're both just fighting for who's liked more.

You were walking in the hallway when you and Kunikida greeted with a long periods of eye contact. Nothing more.
