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.

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.

Even during summer vacation, Nariyuki and the girls have to study hard at cram school. One day, Rizu gets an abysmal "E" on one of her tests. Depressed, she shares her grade with the other girls, which causes an uproar. That's because they mistakenly think she's telling them her bra size.

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.

While Fumino, Rizu, and Uruka all know what their major in college is going to be, Nariyuki still can't decide what he wants to do. Meanwhile, everyone is busy getting ready for Ichinose Academy's school festival.
