The silent and stoic Chateau Dankworth is a bounty hunter. Her target: Son Ryang-ha, a notorious killer known for killing 18 high-class officials in a single night. To this day, his murders remain swift, efficient, and bloody. However, after Son Ryang-ha overpowers Chateau in their first encounter, he reveals his own intentions: he too is after her, aiming for her heart. Son Ryang-ha's attempts to catch her eye are quite unique, to say the least. He offers gifts to her in the form of her current targets, tied up and battered, and will do anything to spend more time together. Reluctantly, Chateau goes along with this act, and so begins the cat-and-mouse game of love between two killers.

Novice bounty hunter Chateau Dankworth never expected to encounter someone capable of overpowering her in combat. Even less so that the mysterious man would take an immediate interest in her—to the point of aiding her missions. However, Chateau makes it clear that she has no plans of entertaining any personal involvement with him. Chateau's company is soon tasked with eliminating Song Ryang-ha—an expert assassin and a former member of a powerful Asian organization. Coincidentally, Ryang-ha is the man that has been pursuing her. Despite his background, Chateau reluctantly agrees to meet with Ryang-ha as part of a deal: in exchange for going out with him, he will provide her with the locations of current targets, dead or alive. But when the past begins to haunt both killers, their arrangement may need to come to an end, as their entanglement puts their lives at grave risk.
