I want a novel. At the beginning, it's about the female lead being the male lead's lover.

In the beginning, it was about the female protagonist being the male protagonist's lover, and the kind with a very high social status. However, the female protagonist did not love the male protagonist, and the male protagonist did not love the female protagonist either. The female protagonist did not want to continue living like this, so she lied to the male protagonist that she liked him. She lied to the male protagonist that he was tired of her and left. Later, they met by marriage, and the male protagonist knew that the female protagonist probably used a trick to make him leave.
