I recommend the following novels for you: The Rebirth of the Swapping Princess, The Four Treasures: Mommy is Super Favorite, The Swapping Princess: The Prince Goes to the Court. These novels all involved swapping plots, including the swapped princess, princess, and the four treasures. The story was full of ups and downs, full of fun and surprises, and extremely attractive. I hope you like this fairy's recommendation. Muah ~๐
