Tarakcheonsa 

One girl, Hajin Seo. She tries to wash her past away, a past filled with murder. But she cannot. A teen star, who just happens to be infatuated with her, tries to cheer her up. But the only two that can cheer her up is Mina, the girl she thought she killed, and a black haired boy. Once the leader of many, all three will become fallen ones.
