rin was a jealous guy. it wasn't obvious, but there were signs. the death glares he'd give you every time you were with another person of the opposite gender wasn't very subtle, after all.

every time he was mad at you, he'd simply just avoid you. he doesn't know how to express that he's upset, other than to avoid you. he'll still talk- just.. more passive aggressively. and vague. very vague. he'll never tell you why he's upset.

"figure it out yourself."

he says, a light scoff escaping his lips when you confronted him about it.

he will never admit he got jealous when he saw you talking and giggling happily with some other lukewarm idiot.
