Wonwoo is such a nerd, but somehow the cutest guy in the campus is his best friend. It would be nice though, if that guy wasn't the blood- demon, if he wasn't going to steal his crush.

Wonwoo had moved to this crowded city for a month due to his parents' separation. Everything was nice, he fell in love with his new school, the students here,... Moreover, he found a new friend, Junhui and he knew it that they would be BFFs. But he totally forgot one thing, his biggest nightmare that is going to turn his life into a horrible mess. But is it the real nightmare? or a daydream?
