I recommend the ancient romance novel,"A Concubine's Daughter Trying to Get Married: The Black-bellied Prince Is Too Difficult to Deal with", to you. The plot meets your requirements. The female protagonist has been reborn as a reliable old driver. She has been pretending to be a pig to eat a tiger, taking in underlings, and taking every step carefully to make you notorious! He became the leader of the concubines who wanted to marry. The male protagonist was also a two-faced prince. He knew that the female protagonist was going to harm him, but he could not help but be attracted to her. The love and hate between the two was also quite impressive. I hope you like this fairy's recommendation. Muah ~😗
