Once she traveled through time, she became Her Majesty the Ice Emperor's first treasure, a lovely, innocent and beautiful girl sister. For her, pretending to be innocent and cute (ah, she is very cute) is really commonplace. Tennis comes easily to her. Is she an all-around genius? No, she is obviously a pervert. With a petite and cute face, he does evil things. She is the mysterious captain of the mysterious team. Who is she? She is just the sister that Atobe Keigo holds in the palm of his hand, nothing more. Tezuka, Kikumaru, Oishi. Ryoma, there are so many men. Everyone, don't be careless, I'm here waiting for you... This article is a fanfic, the author is inexperienced, and I haven't finished watching the anime, but the ending is one-on-one, so I'm definitely not bothered. Princes belong to everyone. So I will give you a recommendation ticket...
