My dear, I think that Return of the Crippled Queen: Supreme Phoenix Beauty and Green Plum Darling: Tsundere Bamboo Horse, Don't Escape are both suitable for your needs! The former was an ancient romance novel, which told the story of the female protagonist being reborn as the daughter of a general and her childhood sweetheart. The latter was a romantic youth-youth campus novel, which told the love story of the female protagonist and her childhood tsundere. Both novels are very sweet and one-on-one love stories. I believe you will love them! I hope you like this fairy's recommendation. Muah ~😗
