Dear, according to your needs, I strongly recommend 'The Empress Doesn't Like Pretty Boys'. The male protagonist of this novel is the emperor, and the female protagonist is the queen. Although there are some differences from the information you provided, the roles of the two are reversed. It's very interesting. The male lead was super two-faced, and the female lead evolved from a cute and soft girl to a queen with a strong heart. The development of the relationship between the two was also very interesting. I hope you like this fairy's recommendation. Muah ~😗
