Synopsis

Soubu High's Cultural Festival continues and Hachiman is stuck carrying out his duty as a committee member by documenting the day's events on film. Komachi shows up and is surprised to find her brother actually taking a bit of responsibility. As the festival enters its last stages, Haruno entertains the audience with a full orchestra performance. Soon enough, as the closing ceremony approaches, Meguri reports that Minami is missing in action. Since she is needed to deliver the closing speech, the group decides to stall for time while Hachiman searches the campus for her. Hachiman eventually finds Minami atop the laboratory roof and realizes she is sulking because Yukino stole the spotlight away from her, despite asking for her help. Hayato and Minami's clique show up to get her, although she refuses to budge. Seeing no other alternative, Hachiman craftily uses reverse psychology combined with Minami's true social reality to guilt her into accepting her duty; using a tone which enrages Hayato. Afterwards, the festival ends as Yui, Yukino, Haruno and Shizuka give their extra musical performance followed by Minami's closing speech. Everyone shows mixed reactions on Hachiman's course of action but Shizuka compliments him for always finding ways to rescue people from their problems, but laments that it breaks her heart since he always sacrifices himself to do so. That evening, at the Service Club room, Hachiman and Yukino discuss how far they've come to know each other, with Yukino hinting that they've become friends. Yui eventually shows up at the club to invite them for an after party hosted by Hayato to celebrate the festival's success. Hachiman ends by pondering that while there aren't any second chances in life, his and Yukino's ideals on society may continue to be seen as deviances. (Source: Wikipedia)
