Fumino continues to live with the Yuiga family. One day, his family needs to go out, leaving Nariyuki and Fumino alone. In gratitude for letting her stay over, Fumino attempts to cook and clean, but fails miserably at every turn!

The school festival is a roaring success! At the swim team's live stage show, Umihara and Kawase perform with Mafuyu in a Full Pure costume for some reason.

Nariyuki is on the verge of failing Physical Education! Uruka tries teaching him how to swim, but she's so bad at teaching that it doesn't do any good.

Parent-teacher conferences are being held at Ichinose Academy. Nariyuki intends to decide his major based on what would be best for his family. Meanwhile, that math professor appears at the Academy.

As a reward for being a tutor, Nariyuki gets to take a short summer course at an entrance exam prep school. He's eager to take the course in order to improve his results, but he meets Asumi Kominami, an academy alumni who is still studying to get into a university.

When Nariyuki goes to a festival, he runs into Uruka and strolls with her past the food stalls, helps Rizu deliver food, and takes an injured Mafuyu to Asumi's father's first-aid tent. In other words, as ever, he's a busy do-gooder.

At the library, a beautiful girl Nariyuki has never seen before sits next to him when he's studying. He's nervous that he's getting hit on, not realizing the girl is actually Rizu, who has changed her hairstyle at a salon.

Downtown at night, Ms. Kirisu finds Nariyuki as he's about to enter a suspicious café and calls him to a halt. It's the maid café where Ms. Kirisu's former student, Asumi, works part-time.

Nariyuki, Rizu, and Sawako go to an open campus event. Nariyuki and Sawako both want the other to become closer to Rizu, so they use every excuse in the book to get away so they can leave the other with Rizu.

After Nariyuki wins a smartphone in a lottery, he can't wait to use it for apps like the dictionary, schedule managing, and the like. He also learns that studying in the bathtub is effective and quickly puts the method into practice.

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.

While Nariyuki and Fumino are talking to each other behind the school, she loses her balance and falls into Nariyuki’s arms. Rizu apparently sees the "hugging" part and looks furious.

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. Nariyuki rolls up his sleeves but is dismayed to find that Fumino wants to be a science major and Rizu a liberal arts major, the exact opposite of where their talents lie. Moreover, they seem to have no aptitude whatsoever for the subjects they’re interested in. Nariyuki advises the geniuses to change their minds, but...

When Mafuyu can't use the bathtub in her apartment, she goes to a neighborhood bathhouse. On the way, she encounters Asumi and Nariyuki, and ends up in the sauna with Asumi. It's so hot that the two get punchy.

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 going to be her tutor. Actually, she's been in love with Nariyuki since middle school which is when he started helping her. Aware of her fellow mentees, Fumino and Rizu, Uruka secretly gets fired up.
