๐I recommend the following three novels to you. They are all stories of people with split personalities described in the first person, including love, mystery, suspense, and humanities: Conan's Chat Room, Memory Killer, and Robb's Inferential Case Book. They are all very good. I suggest you read Conan's Chat Room first. This is a novel about the infinite universe. It tells the story of a person with split personality crossing the world in a chat group. On the other hand,"The Murder of Memories" and "Robb's Mysteries" were based on suspense and reasoning. They told a story about memory and murder respectively. I hope you like these three novels! The above is my personal recommendation. I sincerely hope you like it ~
