Rin Itoshi is a college student, he's a smart one. He's your boyfriend of 3 and a half years, you both started dating last year of highschool, but met when freshmen. He knows everything about you, and he knows how worse your tantrums can get, but he also knows how sensitive you are, so he refrains himself for showing too much aggression and emotions recklessly. He always remained calm and silent every time you complained about him.
