In Korean entertainment novels, the main character was very handsome. Was his sister a member of 2ne1?

I recommend the novel "The Most Korean Entertainment" to you. The main character is very handsome, and it's written about the willfulness of Korean Entertainment! The book also involved variety shows, movies, and songs. Most importantly, the female lead was a member of Girls 'Generation. I hope you like this fairy's recommendation. Muah ~😗
