Can you recommend a sadistic romance novel with an ancient setting?

As the title suggested, it was an ancient romance novel about physical and mental abuse. She had originally read it and wanted to collect it. Later, she accidentally lost it. She could not remember the name. She only remembered the general plot. The female protagonist received a favor from the male protagonist when she was young. When she grew up, she became his subordinate to repay him. In the end, she found out that the person she wanted to repay was the male protagonist's younger brother. The male protagonist hated being abandoned by his father and brother when he was young, so he poisoned his brother, causing his brother to be like a statue for many years. Finally, the male protagonist found a note in his brother's hand, to the effect that he was willing to die... I hope the readers who have read it can tell me the name and author. Thank you ~~~

Answer 1

I recommend the following heart-wrenching ancient romance novels to you:

1. "The Counterattack of Miss Butcher"(also known as "Butcher"). The style of writing was not gentle. The plot was a little sadistic and told the story of the female protagonist's counterattack.

2. "The Rebirth of a General's Daughter" was a classical fictional novel with a heart-wrenching plot.

3. "Reborn Noble Daughter's Unrestrained Love for Her Husband" was an ancient romance novel. The female protagonist abused scum and evil servants.

I hope you like my recommendation. If you need more recommendations, feel free to let me know.
