The living department created by Lina was on the verge of being abandoned. The reason is that it is not possible to give a club room to an unknown club activity. She says she has no choice but to quit Shota, who is also the only member and childhood friend. She doesn't want to let go of the club room where she can do anything. Lina asks Shota to cooperate. Shota, who hasn't refused Lina's begging for a long time, promises her cooperation at this time as well. And the idea that Lina came up with is to set up a new sexual activity club with the purpose of solving her sexual problems and improving her sexual life. Lina immediately tried to solve Shouta's sexual problems.
