A lack of space for all of Jindai High's student organizations prompts a review of each group's numbers. Because they only have two members, the social science club agrees to give up their room through a contest to see which club can recruit the most members of the opposite gender. Sousuke participates, but his poor social skills fail to attract anyone to his club. Kaname, feeling sorry for Sousuke, decides to help out so he can avoid a bet he made with another club.
