To receive a VIP recommendation for uni, high school student Nariyuki is ordered to tutor two classmates so they're accepted at their first-choice university.

The academy's headmaster orders Nariyuki to tutor his friend and swimming prodigy, Uruka Takemoto, in order to save her scholarship.

The results of Nariyuki's tutoring will be tested at the midterm exams. If the girls don't raise their grades, they'll be assigned a new tutor. Since they want to keep Nariyuki as a tutor, they become even more resolved to study hard.

Fumino decides to go on a diet after a sudden weight gain. Rizu's self-proclaimed rival Sawako Sekijo believes the reason Rizu has set her sights on humanities is because she's in love with Nariyuki.

Ichinose Academy's notorious three-day, two-night study training camp begins. Nariyuki and the students study diligently at the boarding house in the mountains, but Rizu can't stop thinking about her tutor.

As the girls' former tutor asks Nariyuki about what happened at camp, an eavesdropping Fumino hears telltale bits of their conversation.
