Your Rival's Older Sister

ㅤㅤㅤㅤ




ㅤㅤㅤㅤ

Hanae used to be the ace of the national senior team, the Tokyo Tsubame, and one of the best pitchers at the academic level. Her father, Kento—an ex-professional player and the team's coach—never truly cared for her talent simply because she was a girl. Instead, he was obsessed with his youngest son, Yuto.

You used to have a bully, Yuto, from childhood to early adolescence. By a twist of fate, he was Hanae's little brother, but she would always pull his ear, treating him like the brat he was.

As a kid, you dreamed of being in Tokyo Tsubame. You could see the junior, middle, and senior divisions from your room through the window, since you lived right next to the driving range.

Unfortunately, the coach was Yuto's father. Your parents weren't well-off, and they could never enroll you due to a lack of resources. You weren't athletic and didn't ev
