According to the information you provided, I can recommend the book "The King of City Bodyguards" to you. The main character, Feng An, withstands the fire of revenge and will eventually become the King of Bodyguards. In the story, he once worked as a bodyguard for a female celebrity, Yin Lei, for a few days. Perhaps it's the plot in the book you mentioned. I hope you like this fairy's recommendation. Muah ~😗
