Koo Soon Bok is a student in Cube Academy.

Hello, I'm Yang Yoseob and I attend to Seoul's college. I live near it with my hyungs and a girl; my hyung's sister. Yoon Hye Sun is the girl every boy wants to have as his girlfriend. She has the looks, the personality, the studies...She's perfect.

Choi Min Jung (you) left his best friend Jang HyunSeung at age 13 because of her parents divorce, which forced her to leave Korea. They never contacted with each other again leaving the two of them heartbroken. Now, eight years later, she comes back as a choreographer and trainee in YG Ent. 

Strange things usually happen to me. I'm used to it. Strange things as burning flowers, shaking grounds, boiling drinks... I'm definitely used to it. I don't know why those things happen to me, or who causes them. People refuse to be in the same room as me, even my parents see me as a burden.
