My Life is to Kill.

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?
