The male protagonist of this novel was the female protagonist's substitute teacher in university. The female protagonist was punished by the male protagonist to do homework with her child. Was the female protagonist's best friend with her brother?

I recommend "Cold and Beautiful Wife, Young Master Lu's Unbridled Love." This was a modern romance novel about a wealthy family. The main character, Ning Yaoyao, was set up by her best friend. However, she eventually returned with her little bun. She kidnapped a tall, rich, and handsome man as her father and started a love story with him. I hope you like this fairy's recommendation. Muah ~😗
