Ever since the kiss, the energetic Junichi has attracted the attention of the girls which makes Haruka jealous. He asks her to kiss him on the eyebrows again but instead she brings him to an abandoned water pump shed where he kisses her behind her knees like a puppy. Junichi wants to kiss her that way again and keep asking her for the next few days. After taking Hibiki’s advice on what to do with their relationship, Haruka lets Junichi spoil her including both of them engaging in some roleplay with him feeding her ramen, much to bewilderment of everyone in the cafeteria. Later that night, Haruka thinks how much fun she had with him.

Junichi, Kaoru, and Masayoshi head to the library to see the new Library committee member, but cause a ruckus there until Ai scolds them. Junichi later offers to teach Ai maths upon learning she’s taking makeup exams. While both of them are taking a break, Ai asks Junichi on what to do with her younger brother, Ikuo, since Junichi acts childish just like him. When Junichi is about to tell Ai his advice during lunch, he unintentionally offends her when he and Miya talks about Sae’s breasts. Junichi later apologizes, even humiliates himself in front of Ai and the swimming team on what he said and entering the school pool without permission. At the beach, Junichi tells Ai to spoil her brother a bit since he just wants her attention. As thanks, she gives Junichi a Inago Mask utility belt, a gift that originally was for his brother. Instead, he teaches her how to use the belt and gives it to group of young boys. That night as she goes to sleep, Ai realizes she likes Junichi.

With the festival behind schedule and Tsukasa's health worrying her, Miss Takahashi suggests they cancel some events, but Tsukasa assures her the festival will be ready unchanged. Knowing that the festival committee is short of manpower, Junichi manages to convince Tsukasa to get their class to help. However, a trio of girls complain and accuses Junichi and Tsukasa's flirting with each other as the root of the festival’s problems. When she fails to end the argument nicely, Tsukasa switches to her real personality and cites the trio’s hypocrisy, silencing and shocking everyone. Later, Tsukasa brings Junichi to the shrine again where she burns her notebook, makes him promise to be hers and seals the deal with a kiss. The next day at PE class, Tsukasa is ganged up by the trio again in dodgeball but the rest of class sides with her, forcing the trio to give up. However at noon, only Masayoshi, Keiko, and Kaoru remains to help Junichi and Tsukasa.
