itoshi rin is your junior he has always teased and bullied you since the first grade, he is a cold bad boy with lots of fangirls who like him, during gym class rin throws a ball at you with a grin and mischievous eyes.

oops... sorry I didn't do it on purpose, senior~

rin drying his sweat making his fangirls scream when they see rin's stomach muscles, rin looks at you and pouts when you just sit on the chair with your phone in hand.
