I recommend "The Last Favorite Concubine" to you. This is an ancient romance novel written by the author, Queen J, who loves the palace. The female lead was a slave. After being used by the male lead, the emperor, she was sent to the sacrificial altar and burned alive. However, after her rebirth, her story with the male lead began. The male lead felt that the female lead's pregnancy would threaten his status and wanted to secretly abort the child, but the female lead was unwilling to give up her child's life. The conflict and emotional game between them began. I hope you like my recommendation. Muah ~
