I recommend "My Wife Is The Final Boss" to you. In order to save the world, the main character marries the final boss as his wife, but he finds out that the villain is himself. So, in order to obtain luck, immortal fate, talent, and other legacies, he begins to counterattack the main character, making the whole story very interesting. There were also many beautiful women in this book. Every one of them was top-notch and very cute. If you want to read a novel about the protagonist having more than 10 wives, this is definitely a good choice. I hope you like this fairy's recommendation. Muah ~😗
