Which novels had protagonists who had transmigrated into the tennis prince? One of the protagonists was Ryuuma's younger sister. At first, they were lovers, but later, they became siblings?

I recommend "The Guide to the King of the Net" to you. This novel was written by Dong Xiao Weiliang. The protagonist was reborn into the world of the tennis prince and became the sister of Ryuuma Echizen. She also experienced the experience of many schools such as Qingxue, Ice Emperor, and Hexagon. Although every male lead was cute, the real male lead was Ryuuma Echizen. This novel has been completed. You can read it without worry. I hope you like my recommendation, Mwah ~😗

I haven't found any novels about " The Prince of tennis ". The novel is about the Phoenix Dances Killer transmigrating to become Echizen Ryugyo and become Echizen Ryuuma's sister. But if you have any other questions about the prince of tennis, I will try my best to answer them.

"Net King: I'm Happy to Be Simple." The female protagonist of this story doesn't know tennis, so there shouldn't be any competition. It was mainly about love. I hope you like this fairy's recommendation. Muah ~😗

I recommend the following two novels to you: <<Reborn in the Primitive Otherworld>>: The protagonist finds himself inexplicably transported to a primitive society in another world. Here, the elves were still a group of monkeys jumping around in the trees. Here, the dragons were just a group of flying lizards. Here, the Titans were still a group of people struggling on the line between life and death. The protagonist happily scribbled on the white paper, but he did not expect that his unintentional behavior would create history. [The First Emperor Monogatari of the Otherworld: Transmigrate into a super rich family in the Otherworld and become a rich family's son.] Infighting and framing did exist, but it was not as terrifying as a palace drama. After being reborn in such an environment for more than ten years, the knowledge of the technological world and the experience of living in a wealthy family allowed the protagonist to obtain a higher level of vision and see a higher level of scenery. At the same time, more desires were born. With such an excellent resource given by the heavens, why not set his dreams a little bigger? Then…create a unified country and become the first emperor! Don't go with the flow! Don't be helpless! Set a goal and walk over it step by step! This was the story of a dream. Forward ~! I hope you like this fairy's recommendation. Muah ~😗

I recommend "The Internet King: Iceberg, Let's Fall in Love." The female protagonist of this book had transmigrated to the world of the Internet King and became Assistant Zhou's sister, but she actually liked Assistant Zhou. Other than Assistant Zhou, she also liked the other male leads, including the arrogant Ryuuma and the cute Ying Er. The male lead was not Ryuuma but Iceberg Tezuka, but the female lead still liked him the most. The ultimate goal was to conquer the iceberg, make him accept his feelings, and start a new relationship. I hope you like my recommendation. Muah ~
