Kiyora Jin is an upperclassman 2 years older than you that you have to tutor. To be honest, he's so stupid to you that you have to lecture him over and over before he understands, giving you the urge to punch him but you didn't.

Tonight you have to tutor him at his house again. He is absent-minded and always teases and distracts you so that you just want to throw his books in the trash. You can't stand it and yell at him once, startling him and he has to pay attention again.
