Because of Haruka's rejection, Junichi feels dejected and unable to sleep well. He goes to the infirmary to get some rest, but he unexpectedly finds Haruka resting there too. Despite what happened, Haruka is still interested with him which lifts his spirits up. After being dragged by Haruka into the school pool the next day, Junichi brings her to the library where he later confesses to her a second time. Unsure what to say, she allows him to confess to her again as many time as he wants and kisses his eyebrow.

Sae's training to become a waitress continues with the help of Junichi and Miya, by practicing her speech skills and practicing how to change uniforms in three minutes--where Miya catches her, in a swimsuit, and Junichi in a compromising position when Sae tripped. They even have had special training in a hot spring with some doctor fish in it to further her speech skills. Sae expresses to Junichi her desire to train even harder, though he has little idea why she wants to be trained more. Her trainings did make Sae become closer to Junichi and Miya; however, one night when Sae has to sleep over at the Tachibana residence, Junichi tells her his wish that he would like to have another younger sister like her, but, to his surprise, she says doesn't want that.

Two years ago, Junichi asked his childhood friend Rihoko, to come and help him select a present for his date on Christmas Eve. Rihoko, who had an unrequited love for Junichi, was sad to find out later that he was stood up. In the present, Rihoko takes a shortcut to school through a hole in a fence, but gets stuck until Junichi helps pulls her out. Realizing she is gaining weight, she seriously swears to her friend Kanae that she'll go on a diet immediately, and gives her cupcakes to Junichi. Kanae seizes this chance to invite him and Masayoshi to go ice skating with them in the weekend. However, upon visiting her seniors at the Tea Club, Rihoko unwittingly breaks her diet there eating snacks until Manaka and Ruriko remind her. Eventually Junichi walks a sulking Rihoko home and even pass by and play on the slide where they and Miya played on as kids. After checking the scales that night, she swears to go on a diet.

Despite the cheerful atmosphere going into finishing work for the Founder’s Festival in time, Junichi is sad about Tsukasa, and plans to ditch the festival again. But when Masayoshi reveals to Junichi about a girl he never got to confess at grade school, he tells Junichi not to make the same mistake as he did, inspiring him and regaining his composure. At the Festival's after-party, Junichi asks Tsukasa for some time alone, and confesses to her. But when he says that he loves her no matter what her personality is, she, confused and angry, beats him up, telling him she erased the old her for him before crying into his arms when Junichi expresses how glad he is to know the Tsukasa he loves still exists. Miss Takahashi catches the two but decides to leave them alone. Tsukasa later tells Junichi that she began organizing the Founder's Festival as a childhood dream to become Santa Claus herself to make people happy but now realizes she's doing it for her own fulfillment.

A shy girl named Risa Kamizaki confesses to Junichi, which the latter accepts and agrees to become her boyfriend, but she wants to keep their relationship a secret. Junichi wants to go the Founder's Festival with Risa and wishes to introduce her to his friends, but, after some thinking, she refuses. Unknown to him, Risa's reasons for not wanting to come is because at the time when he was getting close with Haruka, Kaoru, Sae, Ai, Rihoko and Tsukasa, she was stalking him and prevented the girls from falling in love with him by showing them a doctored photo that Junichi already has a girlfriend. Later, while visiting the park where he was stood up two years ago, Junichi meets Makihara, the girl who stood him up. To his surprise, Makihara never stood him up because a classmate of hers told her that he was waiting for her at the cinema.
