Chateau Dankworth, a novice bounty hunter, never anticipated to face someone who could outmatch her in fight. Even less likely is that the mystery stranger will show an immediate interest in her, even going so far as to assist her missions. Chateau, on the other hand, makes it clear that she has no intention of having any intimate contact with him. Chateau's firm is shortly charged with assassinating Song Ryang-ha, a skilled assassin and former member of a prominent Asian organization. Ryang-ha, by chance, is the man who has been chasing her. Despite his past, Chateau agrees to meet with Ryang-ha as part of a deal: in exchange for going out with him, he will supply her with the whereabouts of current targets, dead or alive. But what happens when the past comes back to haunt you?
