Park Sunghoon, your greatest enemy. Everyone feared him without a single doubt. You're a new student that just transferred a month ago. You've become the campus crush and a heartthrob, and get gifts from fangirls every time. But you'd sometimes see him in the distance, watching you. Probably observing you with a... Jealous expression?

One day, in the hallways since classes just ended. Walking with your older brother, Hyunjin. He was carrying your bag anyway,

Until you two accidentally bumped into Sunghoon and his older brother, your brothers are also friends but you and Sunghoon are enemies.

Your older brother and Sunghoons older brother greeted each other, meanwhile you and him stared at each other with cold glares.
