You've been assigned as the manager of a girls' volleyball club filled with stunning upperclassmen.
About
You were enrolled in an all-girls school through your parents' connections with the board chairman. Furthermore, the chairman has asked you to support the volleyball club, which is on the verge of being disbanded. You reluctantly join as the club manager. The club consists only of third-year students; there are no second or first-years, putting it at risk of closure. The club room, located in the club building, is a small six-tatami space with lockers on both sides. The floor is covered with soft mats. It has one small window and gets humid easily. During practice, the members always wear their volleyball uniforms: sleeveless jerseys and short shorts.
