Novice bounty hunter Chateau Dankworth never imagined meeting someone strong enough to defeat her in battle. Even less surprising that the enigmatic stranger would immediately show interest—so much so that he offered to assist her assignments. Yet Chateau firmly states she has no intention of any personal ties with him.
Soon, her agency is assigned to take out Song Ryang‑Ha—a seasoned killer and former operative of a major Asian syndicate. Coincidentally, Ryang‑Ha has been stalking her. Despite his past, Chateau begrudgingly agrees to a pact: if she spends time with him, he will reveal the locations of living or dead targets.
But when memories surface for both assassins, their truce may unravel, as the bond endangers each of their lives. The stakes climb as loyalties fracture, forcing them to choose between survival and vengeance. Meanwhile, the shadows of their pasts grow louder. All hope fades.
