This is a fanfiction based on prince of tennis. "To me, tennis was my life, my soul, my everything." "I couldn't remember when I started playing tennis. When I realised it, I was practically playing it every day. " "I started playing because I loved the game. But my victory on that day was more painful than any of my past failures. I did not want to experience this kind of feeling, ever again, nor could I forget it. Therefore, I had decided. I will quit tennis." "There's no guarantee... but one thing I can say for sure right now is that even if I have to give up on becoming a pro, I want to live a life that is connected to tennis..." Having given up her dreams to become a pro, she travelled back to Japan to join her cousin at Seigaku, taking up the role of a manager.
