Hey, I recommend the book The Emperor's Darling: The Heart-Stealing Little Sweetheart to you. The main character of the novel, Luo Ranxue, traveled to ancient times and became husband and wife with the emperor who had a harem of 3,000. Although she hated the ancient polygamy system the most, a certain emperor had launched a series of sweet concubine plans, and this woman had started to run away time and time again. Let's see how they would deal with this complicated relationship. I hope you like this fairy's recommendation. Muah ~😗
