I recommend "The Art of the Flowerscape" to you. It's an ancient romance novel with the main characters of the male and female protagonists, the childhood sweethearts. The female protagonist had a love-hate relationship with the male protagonist because of a misunderstanding, and the male protagonist abused the female protagonist in various ways. However, the story also had a slightly sweet and slightly sadistic element. In the end, the male and female leads could still get together. I hope you like this novel ~
