It should be the book "The Imperial Concubine Is at the Top of the Entertainment Industry". The female lead's surname was Su, and the male lead was the CEO. In addition to them, there was another pair of lovers, the male lead's eldest brother, the second brother of the movie king, and the third brother of the eSports champion, who were all related to the female lead. The male lead's sister was also one of them. I hope you like this fairy's recommendation. Muah ~😗
