Inhasaki, a first-year student at Hakomine Gakuin, a prestigious local school who has participated in the national baseball tournament, becomes interested in a game she happens to watch and becomes the manager of the baseball team. Her senior manager, Nozomi Kurimiya, who is caring and kind, and the refreshing baseball team members. Saki's heart is excited as she looks forward to the days of youth with her teammates that are about to begin, but... ``The manager is the one who takes care of the club members in every way possible so that they can be at their best.'' What awaits her is... It was a tradition of sweat and lust. In order to take care of the sweaty club members, she works as a sex worker. The sexual services performed wherever she was were her virginity.
