Wayu is a trained assassin who falls in the love with Pavarin, the daughter of a rich business man who is also an underground drug lord. Orphaned at a young age and trained to be a hit-man with no attachments, his heart and life is put to the test when a girl with a bright smile melts his stone-cold heart. With underground drug cartels fighting turf wars and the police hot on the case, can their love stand the test and can they make it out alive to the end?

他，残酷的杀手，是否会为了她，不再做爱情杀手；她，善良的女孩，是否会为了他，走出黑暗迷雾，抓紧他的手。
