I recommend "The Queen's Rebirth: Please Bow Your Highness" to you! The female protagonist, Mu Yuluo, was a useless daughter who had been trampled on by everyone. However, she was reborn in an accident and became an all-rounded queen. She began her path of revenge. In the story, there was a cold and indifferent male protagonist, Young Master Bei Gong. He was the most famous piano genius in the country. He only composed music for the female protagonist and doted on her. This novel definitely meets your requirements for a revenge modern school novel. There is only one female lead, and her name is Mu Yuluo. I hope you like this fairy's recommendation. Muah ~😗
