There are two geniuses at Ichinose Academy: Fumino Furuhashi, a liberal arts prodigy, and Rizu Ogata, a scientific whiz. Nariyuki Yuiga is a talented student who has contempt for them, especially as he’s aiming to get a "special VIP recommendation.” But then, as a condition for receiving it, Nariyuki is ordered to tutor Fumino and Rizu so that they’re accepted at their first-choice university...

Uruka Takemoto has been a friend of Nariyuki's since middle school and is a swimming prodigy who should have a brilliant future ahead of her, but her academic grades are so bad that she's in danger of losing the college scholarship she's counting on. The academy's headmaster orders Nariyuki to tutor her, too. Uruka hates studying but suddenly becomes eager when she hears that Nariyuki is goin...

The results of Nariyuki’s tutoring are about to be put to the test with the midterm exams. If the girls don’t raise their grades, they’ll get a new tutor. The three of them want to keep Nariyuki, though, so they become even more resolved to study hard for the exams.

Fumino is determined to go on a diet after a sudden weight gain. Rizu's self-proclaimed rival, Sawako Sekijo, has the wrong idea that the reason Rizu has set her sights on humanities is because she's in love with Nariyuki, and she tries to test Rizu's "love."

Ichinose Academy’s famous three-day, two-night study training camp has begun. Nariyuki and the students study hard at the boarding house in the mountains, but Rizu can’t stop thinking about her tutor.

Nariyuki is summoned by Mafuyu Kirisu, the girls’ former tutor, who interrogates him about the camp incidents. A worried Fumino, waiting outside the student guidance counselor's door, hears snatches of the conversation, including the expression "illicit sexual conduct."
