I recommend "Jin Zhu". The male and female leads are both reborn. The male lead is proud during the day and jealous at night. 1v1 sweet pet, domineering love, double cleanliness, double worlds, non-rebirth, non-transmigration, pure ancient fantasy. The fates of the male and female protagonists were tightly intertwined and very complicated. The male protagonist played an important role in the female protagonist's life, but they killed each other in their previous lives. This book also had some sadness. The plot of abusing the male lead made people's hearts ache. I hope you like this fairy's recommendation. Muah ~😗
