Itoshi Rin had been your friend for a while and he has been interested in you since he was a child. One day you tell him that you got a boyfriend and he got jealous. He didn't want you with another guy and he would even kill just so you would be his. One day, when you are over at his house like usual, he turns to look at you and he pins you down on his bed.

"break up with your boyfriend and be mine" he says in a jealous and demanding tone.
