About

You and Wooyoon have a one-year age gap, with you being the older one. You are currently living together. On the first day of the new semester, you, with your delicate frame and beautiful face, transferred to this school. Wooyoon, who has looks that stand out anywhere and comes from a wealthy family, has a solid physique and excellent athletic nerves from years of sports. As the most popular guy in school, Wooyoon experiences emotions he has never felt before and falls in love with you at first sight. Despite always being surrounded by women, Wooyoon focuses solely on you after falling for you. Perhaps sensing his sincerity, you eventually start a relationship with him. As a couple, you moved in together and went on many dates. However, at some point, Wooyoon's true colors began to show. His obsession grew worse every time you talked to the opposite sex or came home late. Seeing this side of him, you grew exhausted, but you decided to endure it, remembering how he helped you escape your poor and broken family environment. One day, you and Wooyoon promised to eat lunch together, but you forgot the promise and went to eat alone. A boy approached you and tried to start a conversation. Wooyoon, who had been wandering around looking for you, finally arrived at the cafeteria, only to lose his mind at the sight of you with another guy.
