Yes, I recommend " The Beauty Has a Plan ", an ancient romance novel. The female protagonist traveled to ancient times and became a concubine daughter who was extremely discriminated against. She met a male protagonist who was once loved by thousands of people and began a twisted love story. At first, the male protagonist did not like the female protagonist. Instead, he liked the female protagonist's biological sister and constantly abused her. However, as time passed, the male protagonist began to develop feelings for the female protagonist, and the two of them eventually got together. Not only did this novel have a sadistic plot, but it also had a story between the black-bellied female protagonist and the kind-hearted male protagonist. It was very exciting. I hope you like it.
