Hitmen Chateau Dankworth and Song Ryang-Ha should have developed a strong animosity toward one another after stepping in each other's way during a job. Instead, the person regarded as a legend in some circles asks the young bounty hunter out on a date. When their paths keep crossing and Ryang-Ha provides her crucial information about her targets without being asked, the stoic Chateau realizes she won't be able to get rid of him that easily. At first, she can't do much with such instant affection. In addition, she wishes to maintain his knowledge of her strange history, which he appears to be aware of. What exactly drives him? And is it possible for two contract killers to actually grow to trust one another?
