I recommend a novel called " The Great God Lives Next Door and Pushes His Beautiful Wife 1001 Times ". The male and female protagonists are neighbors, and the female protagonist is a little tyrant when she is young. She will protect the male protagonist. There were also scenes of them being together in high school. This novel is a modern romance and entertainment star novel. The male and female leads are both physically and mentally clean. 1v1 is a favorite novel. It definitely meets your requirements. I hope you like my recommendation.😗
