With final exams approaching next week, Class F students face college admission consequences. Kotoko persuades Naoki to tutor the entire group, leveraging his prior help with her studies, much to Irie's irritation. Naoki's guidance enables most students to pass, except Kinnosuke, who refuses assistance from Irie due to pride. On Christmas Day, the class pools resources to buy Irie a gift, resulting in a Kotoko doll. Meanwhile, Kotoko works diligently as a waitress to purchase her own present for Irie. The episode highlights the group's academic struggles and their distinct approaches to celebrating the holiday while navigating their interpersonal dynamics and educational pressures.
