Novice bounty hunter Chateau Dankworth never anticipated facing someone capable of overpowering her in combat. Even more surprising was that the mysterious man would take an immediate interest in her—to the extent of assisting with her missions. However, Chateau makes it clear that she has no intention 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 who 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.
