The book I recommend to you is "100 Points Honey Pet: A Guide to Finding a Prince Charming Husband". It's a modern romance novel about wealthy families. The female lead was called Yun Xi. After she transmigrated to the modern world, she slept with her ex-boyfriend, but she avoided him like a viper. However, her ex-boyfriend had been pestering her because he had doted on Yun Xi since she was young. Then, the story between them unfolded. I hope you like this fairy's recommendation. Muah ~😗
