Lee Jonghyun is 17 years old. He is still in high school, and he is working hard to become a member of a band. He's handsome, nice, outgoing, but also a little shy. He has never experienced love before....but everything changes once he's a senior in high school. To be honest, he's been liking her ever since he first saw her. This is something called "love at first sight." Well, his best friends are Kris Wu Fan and Leeteuk. The girl he likes is Juniel...but he never had the chance to tell her. Even thought he only likes her, a lot of girls are in love with him.... What will he do?
