I recommend the two books,"The Fourth Miss of the Prime Minister's Residence" and "The Regent Prince Marries a Husband". The Fourth Miss of the Prime Minister's Residence met with misfortune and grew up wandering outside. She was adopted by her grandfather, Duke Dingguo. After returning to the Prime Minister's Residence, her mother did not recognize her, but she was saved by the young prince of the enemy country. The plot of the River and Mountain Strategy was that the female protagonist was cursed to unify the world a hundred years later, while the male protagonist was the regent. There were ups and downs in the relationship between the two. I hope you like my recommendation, Mwah ~
