I recommend the following novels to you: 1. " The Host Is A Real Big Boss ": This novel has a story between a psychopath and a black-bellied male protagonist and a white-cut and black-level female protagonist. It suits your needs very well. 2. " Get Dressed: The Male Heroes Have All Fallen ": The male protagonists in this novel have all turned black, and the female protagonist is controlled by them in every way. The whole story is very suspenseful and conflicted. 3. " The Host of the Quick Wear was forcefully kissed by the male protagonist after his death ": The male protagonist in this novel is very sickly and delicate. The love between him and the female protagonist is very twisted and bizarre. It matches the black-bellied male protagonist you like. I hope you like my recommendation.
