I recommend this novel, Life Exchange, to you. It is a real-life novel about family and emotions written by the author, Lian Er. It told the story of three pregnant women who exchanged their identities because of fate. Other than that, there was also an ancient romance novel called "Comedy Time Travel: My Beloved Concubine, Please Turn the Cards Over." It told a funny story about the exchange of souls between a man and a woman. I hope you like my recommendation. Muah ~
