Wayu is a trained homicide who falls in the love with Pavarin, the son of a rich business man who’s also an underground medicine lord. Orphaned at a youthful age and trained to be a megahit- man with no attachments, his heart and life is put to the test when a girl with a bright smile melts his gravestone-cold heart. With underground medicine syndicates fighting turf wars and the police briskly on the case, can their love stand the test and can they make it out alive to the end?
