Full Metal Panic! (2002)

S2E10 Uncontrollable Bluebird

Due to limited space at Jindai High, a reassessment of each student organization’s membership is necessary. With only two members, the social science club decides to relinquish their room through a competition to see which club can enlist the most members of the opposite gender. Sousuke enters the contest, but his awkward social skills hinder his efforts to draw anyone to his club. Feeling sympathetic towards him, Kaname steps in to assist, hoping to help him dodge a wager he made with another group.
