Revenge. It was always on her mind. Her life goal was simple: find out who killed her parents and kill them. What she didn't expect was to fall in love with some who just as, if not more ruthless than her. Limits will be tested, family ties will be strained. Time is running short. She has to put a bullet in their hearts, before they put them in hers. Love. Death. Drugs. Gangs. The mafia. This is her life, a life of darkness. This is Kim Yun Hee.
