Jung Yulji is the most tomboyish girl at SM academy. She hangs out with her 6 best friends B.A.P, who are as crazy as her. They all hang out 24/7, Yulji also lives with them, her parents allowed her because her cousin Daehyun is there to protect her. But what will happen if an accident happen involving Yulji and her enemy? Will it leave to love or heart break?

Do Kyungsoo is one of Yulji's enemy's at school. He is very quiet and shy, but once you get to know him he is loud and very weird. Even though Yulji doesn't like him, he will keep on liking her. What if an accident happen involving him and his crush? Will he help or just break her heart?

Exo-k. Yulji's worst enemy. Only bullied Yulji because they thught she is a . They don't like 's because of one accident. D.O is the only one that likes Yulji.

B.A.P. Yulji's best friends. Hate exo-k because they bully Yulji. They are all very weird and really protective of Yulji.
