I love you, even though you hate me.

Kaminari and Shinso are dating. Everyone in the class knows that. Izuku tutors Kaminari. Also common knowledge. Izuku was tutoring kaminari before his and shinso started dating, Shinso doesn't like izuku because he thinks he's fake. Izuku has a crush on shinso and kaminari, he hasn't tried to act on it because of Shinsos obvious dislike of him. Shinso has started sitting through every tutoring session.
