I recommend "The Internet King's Iceberg Let's Fall in Love", which is a light novel-a doujinshi derivative novel. The main story was about the female protagonist who came into contact with the King of Nets because of tennis. After being hit in the head, she unexpectedly became Zhou Zhu's sister. The female protagonist liked Assistant Zhou, but now she had become his sister. However, the female protagonist did not care about these details because she fell in love with the male protagonist, Tezuka Kunihiro, an iceberg-like figure. In the end, the two of them became a couple, and the sweetness was great. If you like the sweet stories of the iceberg male protagonist, this book will not disappoint you. I hope you like this fairy's recommendation. Muah ~š
Sayuri Sugawara was a Japanese web novelist. Her main works included Journey to Fantasy World and Superpower War. One of her masterpieces was Journey to Fantasy World, which told the story of the protagonist's pursuit of power in the fantasy world. Her works were unique in style, with fantasy and science fiction as the theme, and were deeply loved by readers.
Friendship is a common theme. The OC usually forms a strong bond with Sugawara, which could be based on shared interests like volleyball or just mutual understanding. For example, in many fanfics, they support each other through tough times.
