I recommend the book "After the Hidden Marriage with Mr. Mu" to you. The female protagonist, Su Yanjin, is also a university teacher. She married the young, promising, cold, and black-bellied Mu Yanxing. They were constantly sweet and doting on each other. The male protagonist doted on the female protagonist, making people envious. The book also had the background of a wealthy family, and the whole process was 1v1. There were no plots such as fighting for favor or love triangle, only pure happiness and love. I hope you like this fairy's recommendation. Muah ~😗
