Rikkai University, but Make It a Love Rival Showdown

[Blurb] For some reason, Tsukimisato Yukinobu transferred from Kaijo to Rikkai. At his first school festival after transferring, Tsukimisato Yukinobu drew a maid costume. Looking troubled, he asked Sanada to help tie the drawstrings at his back. Sanada adjusted his cap and nodded. But when his fingers touched the thin drawstrings, his ears turned red beneath his dark, tousled hair. · The regulars on the tennis team went to visit their hospitalized captain. As usual, the new student Tsukimisato was shy and reserved. When he was pushed in front of the captain, he could barely speak. But after everyone else had left, Tsukimisato Yukinobu returned and met Captain Yukimura on the hospital rooftop. Captain Yukimura had asked him to come. · Kirihara had always been quietly competing with the new upperclassman, Tsukimisato. The other's usual quiet, bashful self was completely different from the calm, sharp player he became on the court. That guy's really putting on an act. Kirihara felt a little contempt for him. Just a little. After a match he still couldn't win even in his demon form, Kirihara sat with his head bowed in the supply room. It was so quiet he could hear nothing but his own breathing. Then he heard footsteps outside. The door opened, and sunlight and a faint fragrance drifted in. “Kirihara, may I come in?” The main story is complete. More fantastic alternate endings are unlocking one after another [Reader's Notes] 1. The first version of this blurb was written around 2021 and had been sitting for so long that I could no longer write the story according to my original plan, so I revised both the blurb and the main plot. I sincerely apologize to everyone who favorited the first version. 2. The main focus is unrealistic tennis, and the setting's timeline has been changed to high school. 3. There's lots of everyday life and affectionate moments. There are multiple endings, and the match scenes probably won't be very long. The overall story probably won't be very long either. Theme: The passion and ambition of youth are the most beautiful parts of adolescence.
