The book I recommend to you is 'Big Boss Has Retired.' The main character is also called Xiao Ling. The book described how the female protagonist owed the male protagonist a million dollars after she got drunk. In order to repay the debt, the female protagonist had to sell herself to become his fake fiancée. From the beginning, the two of them schemed against each other, gradually understood each other, and finally came together in a love story. I hope you like this fairy's recommendation. Muah ~😗
