Uka's high school life has really taken off...but seeing Kai rush to his ex-girlfriend's aid brings her crashing down to earth! After all, why wouldn't he? Serina is beautiful, strong, and popular—the total opposite of Uka—so it's only fitting that he'd come to her rescue. Still, if Uka's learned anything from Kai, it's to give everything her best shot—such as volunteering to lead the class's upcoming culture festival preparations! The only problem is, does a shy introvert like her truly have what it takes to corral a bunch of rowdy, uncooperative high schoolers?
