So in some twisted moment, our beloved Atobe Keigo, the captain of Hyoutei tennis team decides to open a gakuensai (school festival) which involved some schools’ tennis team. He is also backed by their coach, Sakaki Tarou. Shizuka is chosen as the Uneiin (manager) for her school team (whatever you pick) and she’ll be helping them in the preparation and others as well as stealing their hearts. The boys will also join an attraction (drama, band, etc), though you're barely involved in it. They’re fun to watch.
