According to the information provided, I recommend " The Romance of Love " to you. This novel was about one of the top three male idols of TF BOYS who transferred to the female protagonist's class. The female protagonist was a brainless fan of TF BOYS. Through her contact with Wang Junkai, Wang Junkai finally fell in love with the female protagonist. There were also childhood sweethearts in the book. I hope you like my recommendation.π
