I recommend "Spring in the Tomb Is Cold, Honeysuckle Warmth" to you. This is a modern romance novel about urban life. After the mother of the protagonist of the novel died, she was forced to become a lover of a strange man in order to raise money for her father's medical expenses. It was similar to the plot described in the question. I hope you like this fairy's recommendation. Muah ~😗
