Chateau Dankworth is a bounty hunter who crosses paths with Song Ryang-ha, a professional hitman, during one of her jobs. Rather than fight her, he begins shadowing her and trading her valuable information in exchange for a date. Wary and unwilling to let him in, Chateau keeps her distance even as Ryang-ha makes himself impossible to shake — a pursuit that grows more dangerous as their separate pasts start to pull them toward the same enemies.
