[Laughing Ruffian Concubine: Ghost Lord, Too Secretive!] This novel suits your needs. The main character was a woman who had been reborn. She used to be a prodigal son, but after she was killed, her soul slept in a woman's body. She obtained the help of a beautiful ghost to successfully lose weight and help the beautiful ghost take revenge. I hope you like this fairy's recommendation. Muah ~๐
