I recommend the book "The City Lord's Wife Is Hard to Chase" to you. Although it doesn't completely match the plot of the city lord's sister and the city lord, it's also a love story between the city lord and the city lord's wife. It's worth reading ~ I hope you like this fairy's recommendation. Muah ~😗
