Son Seungwan the boy with musical interests and was shy about how live performance in school. No one really knows about his talent but his sister, Sooyoung. Seungwan loved music ever since he was 3 and now he could play instruments he picked up so far. After years of playing he was now in high school still playing instruments he really loves playing with. People know him as the shy weak boy but things changed after seeing him in Physical class( is that what they called it when you're in high school?).

Bae Joohyun the girl who was the visual queen of the school known as Irene was popular among students in the campus. The moment she landed a foot in this school, people had eyes on her. Joohyun was the girl which boys fell for but she never returns the same feeling for any boys that have confessed so far. She herself never found any guy interesting in the campus so she never bothered rejecting them. All she focused on was her school work because she was the type who really cared for their future for a living.
