Welcome to the Sex Life Club!
The club Lina created for her life is in danger of being abolished. The club is in danger of being closed down because they cannot afford to give a club room to a club that has no identity. Shota, the only member of the club and a childhood friend, had no choice but to quit. Not wanting to give up her clubroom, where she can do anything she wants, she asks Shota to help her. Shota, who has never been able to refuse Rina's pleas, promises to cooperate with her again. Rina comes up with an idea to start a new club, the Sex Club, to solve sexual problems and improve sexual life. Rina immediately tries to solve Shota's sexual problems.
