Maneater

In a rough neighborhood where police rarely intervene, Nabi runs a quiet little hair salon. But behind her sweet appearance lies a deadly secret: she's a man-eating monster who only targets intruders, specifically sexual predators. With her "supply" running low, Nabi captures an unexpected trespasser, a contract killer named Kang Eunchan who was sent to assassinate her. Before he knows it, he's overpowered and locked away in her secret underground shelter. As Nabi begins to care for him in her own strange way, Eunchan finds himself reluctantly drawn to her and even offers himself up as her next meal. Between a beautiful predator and a killer too charming to eat, their twisted relationship begins to spiral, just as other men start appearing with their own reasons for wanting to fall under Nabi's control. A sharp, bloody love thriller with one hell of a bite.
