Kim Kibum was the perfect student. He was smart, clever and popular. Every girl in the school wanted to be with him, but none has succeeded. Everyone else wanted to be friends with him, but he didn't believe in friendship. Kibum never had any problems with anyone until now. A new year had begun and he was placed as class president in his new homeroom. Oh Minah was always a quiet student who had happened to be in the same class. One day, on her way to the classroom to grab her notebook, she finds out a secret of his that he's been keeping from everyone for so long....What will happen to Minah and Kibum now?
