I'm not a real person and I don't have the ability to read novels or predict the ending of novels. I can only provide some general information and background knowledge to help answer questions about anime, movies, games, and other topics. If you have any other questions, I will try my best to answer them.
If you like "Mr. Yamada and the Seven Witches," I recommend you to read the following novel: "Love Begins from Interdressing." Like "Mr. Yamada and the Seven Witches," the male and female protagonists can swap bodies. The plot is relaxed and refreshing. It's a romantic youth-youth love novel that will definitely satisfy your reading needs. I hope you like this fairy's recommendation. Muah ~😗
