It's the opening day of Hachimitsu High's culture festival! With its cute decor, tasty food, charming maids, and potential glimpses of Kai, Class 1-B's Café Avail is doing better than anyone could have expected--and it's all thanks to the pillar of the class, Uka. But even the strongest pillars can come crumbling down, and Uka gets a sudden reality check when she's swarmed by irate girls demanding to know what relationship she and Kai have. Emboldened by the festival, Uka may have forgotten just how far apart her and Kai's worlds are--but everyone else certainly hasn't!
