One of the two male leads is pushy about his romantic interest in the other. In the early part of their relationship, the second man wants nothing to do with the first, who is persistent to the borderline of stalking. They soon become close, and the romantic chemistry softens the more dubiously consensual elements. A male recurring side character referred to as Lustful or Lovelace Ghost is constantly sexually predatory. Usually he is leering at or otherwise harassing women off and on during his scenes. There are two on-screen scenes of attempted rape and it is clear that he is a serial rapist offscreen. He only appears in the first episodes of the show. A female recurring side character referred to as Poison Bodhisattva is an assassin with, literally, a poisonous kiss. She acts simultaneously highly sensual and gleeful about violence, which makes for a disturbing combination. Spoilers: in one of the show's most disturbing scenes, roughly 1/4 of the way through the show, Du Pusa tortures a teenage male major character. He is restrained and distressed. She is extremely physical with him including kissing and caressing his face (and thus poisoning him). The scene is presented as appropriately disturbing.
