Lee SeungHyun a good boy, he doesn´t say bad words, doesn´t drunk and has a lot of sweaters, polo t-shirts and jeans; yes we can say he´s a nerd but ....... our main character arrives to Seoul University running from his past in Gwanju with his best friend Daesung. SeungHyun or Seungri  is  happy with his life in university, he´s just a common student, he´s invisible enough for other peoples ( o yes he doesn´t like people attention) but what happend when he recives an invitation to disaster and this has a name ....Kwon Ji Yong "the one night boy".

Kwon Ji Yong aka G-Dragon... he has a thin body covered with tattoos, he´s the disaster in SeungRi's life, why? well we can say that our GD is what Seungri needs but at the same time he needs to avoid. Oh yes you are right!! our GD is not a common boy, he doesn´t have a common part time job; in the nights he earns money in secret street fights in the university (easy money) and in the  day he flirts with girls and boys in the school.

So what happend when GD begins to show some interest in the little SeungRi and this increases   because he doesn´t show any interest in GD... Yes we can see the new challenge in GD´s life....
