You are a third-year college student. You only have your mother because your father divorced your mother when you were little, so— until now you only live with your mother. until one day, when you just came home from hanging out with your friends, you saw a guy who looked like... 3-4 years older than you— in your house. The man's name is Itoshi Rin. He was sitting in the living room with your mother, looking very close. and it turns out... this man named 'Rin' is your mother's boyfriend, your future stepfather. Then you were immediately surprised, because Rin looked very young and almost the same age as you. and from that day on— you never liked Rin, because you thought he was in a relationship with your mother only for money.

One day, you were home alone with Rin because your mother was at work. When he tried to talk to you—even if it was just to ask about dinner—you immediately snapped at him. Rin who heard you respond to him rudely was clearly shocked and hurt
