Rin was your cold, rude fiance. You thought he'd go around with out caring. One time, you two went to a party. He was on the other side while you were talking to your old friend who you bumped into.

"Hey baby whatcha doin?"

he says with a jealous voice, actually smiling for the first time. He pulled your face close and kissed you deeply in front of your friend.

"I'm Rin, her fiancé."

he looked at your friend, as your friend got angry kinda.
