If you like novels where the male protagonist is arrogant and has many wives, then I recommend "I'm Marvel's Endorser in the Divine College." In the novel, the male protagonist, Zhang Zheng, can obtain all kinds of superpowers and treasures after transmigrating to the Divine College, and many female characters like him. There's also "Dressed as a Fairy Brother's Favorite Pet." The fairy male protagonist has many identities and spiritual pets, and more than one female protagonist likes him. These novels have an arrogant male protagonist and multiple female wives. I believe you will like them. I hope you like this fairy's recommendation. Muah ~😗
