After Linda finds them, she explains that she was out on a club retreat with the Festival Club, and brings Banri and Kōko to their campsite. After returning, Banri is greeted by Nijigen, Mitsuo, and Chinami, who are all relieved to know they are alright. Later during a break, Banri, Mitsuo, and Chinami get together to talk, but they are interrupted by Kōko, who begins to berate and belittle Chinami, causing Mitsuo to leave with Chinami and leaving Banri to comfort a remorseful Kōko. After class, the pair once again encounters Linda, who invites them to participate in one of the Festival Club's dance rehearsals. Banri decides to join, while Kōko considers the idea. Later that night, Mitsuo tells Banri he will settle things with Kōko, because he wants to pursue a relationship with Chinami, and the next day Mitsuo flatly rebuffs Kōko's affection in front of Banri. Kōko asks Mitsuo if their time together meant nothing to him, and Mitsuo replies that while he treasures their time together, he only sees her as a childhood friend. Kōko angrily yells at him to forget their history, driving Mitsuo away. Kōko yells at him to disappear, but realizes her words are hurtful to Banri, causing her to continuously apologize in tears. After a few hours, Kōko and Banri are invited by a girl called Nana (most likely a reference to Nana Osaki from the manga and anime NANA) to her concert. Kōko goes to vent her frustration, but is thrown out, and spends the night at Banri's apartment. Kōko reveals she needs him, while Banri confesses his love for her. After she leaves, she texts Banri, encouraging him to not forget about his lost memories, which motivates him to return to his home in Shizuoka, where he finds a scrapbook containing pictures of himself and Linda in high school together.

Kōko tells Banri that she loves him, but before he can respond Kōko is arrested for stealing a bike that she used to catch up to Banri. At the police station, Kōko is cleared of any charges, and after explaining the reason behind her sudden confession, Banri reciprocates and the two officially become a couple. The next day, Kōko openly expresses her love for Banri as they walk to school, and their relationship is met with disbelief from Nijigen, and mild surprise from Mitsuo, who has dyed his hair blonde out of depression from being rejected. When Chinami comes to greet them Mitsuo flees, and Chinami says that he has been avoiding her, while explaining the reason she rejected him was because his confession was made in public. Linda soon appears, and Banri flees, noting that he has been avoiding Linda since their last conversation, despite her constant attempts to speak with him again. As time passes, Banri and Kōko enjoy their time as a couple, but Banri continues to ignore Linda, which upsets her, and causes Nana to take notice. One day, Banri is called back to his apartment because of a plumbing leak, but when he arrives he meets Nana again, who reveals that she is his neighbor, and that she faked the leak to get him to meet with Linda. Back in Banri's apartment, he apologizes for his behavior, and the two rekindle their friendship, just as Banri gets a call from Kōko who worries that Mitsuo might be in trouble.

He discovers the hidden picture of Linda and himself is missing. He tries to go to the hospital by himself, but Nana finds him and takes him there. On the way home he tells Nana that he had the wrong idea about her, and that she is actually really nice. She listens with her usual cool attitude. Once home, she passes him off to a waiting Linda, who accuses her of beating up Banri. Nana tells Linda that she only helped him, and leaves Linda and Banri by themselves. Linda takes care of Banri for a while, feeding him water and medicine. Banri reflects on the conflicting emotions he experiences about Linda and Kōko. Kōko arrives with a bouquet of roses and accuses Banri of cheating because he's alone in his apartment with Linda. Banri and Linda are taken aback until Kōko reveals she's kidding, tossing the roses aside. 2D-kun and Mitsuo arrive and jokingly argue over who caught the bouquet and will get married first. Kōko assures everyone present that she was really kidding, and that she knows that Banri would never cheat on her. She goes a little over the top about the subject, and gets chided by Linda who tells her to cut it out. Kōko, in turn, chides Banri for not telling her that Nana lived next door, but forgives him anyway. She also thanks Linda for taking care of Banri, but Mitsuo suspects she is not being honest about her true feelings. They begin to argue, but Linda stops them for Banri's sake. Kōko admits that having another woman take care of him before she could get there did make her a little jealous. Linda admits that Nana took care of him first. Everyone discusses summer vacation plans, and decide to go to the beach together. Later that night, Banri awakens and finds Kōko still there and watching over him. Kōko apologizes for not taking care of him properly and making a fuss when he was not feeling well. She becomes depressed, telling Banri that she could never be a good girlfriend. Banri gives her an assuring hug, and asks if she's not entirely over her own cold yet. She assures him that she couldn't have come and seen him if that were the case. She admits that she wanted to go to the beach only with him, and asks if he will take her when he's better. She further states that "it doesn't have to be Paris", referring to her ideal "first time" location. Banri promises that he will take her once summer vacation arrives.

Banri and Kōko ride the train and discuss Kōko's new Festival Club nickname "RoboGirl", so named because she looks like a robot when she dances.They look forward to the Awa dance festival and the beach trip they have planned. Banri worries about whether Kōko is the one who took the photo of Linda and him from his apartment. They meet up with the rest of the Festival Club, and discuss the preparations needed before the festival. Afterwards Banri speaks with the upperclassmen and asks for advice about his beach trip with Kōko. When they find out that Banri only intends to take her by train for a day trip, they tell him that a classy girl like Kōko won't be happy with the low-budget, simple trip he has planned. They advise him to get a job and make some money. Later Kōko tells him that she doesn't want him to get a job because it would mean they wouldn't get to see each other much. Kōko offers to pay for both of them on their trip. She tells him that she wants to spend as much time with him as she can, and admits that she worries about what he's doing when they're not together. She says that she knows she is awkward, overbearing, and annoying, but says she's learning to hold back. Kōko then tells Banri that she wishes she could shrink him down so that she can keep him with her in her bag for safety. Oka-chan walks up and says hello, then announces that she is on her way to her part time job. Oka-chan advises Banri that her employer is looking for more people, so they follow her to the upscale cafe where she works. Kōko, though, forbids Banri from working. Banri visits Nana to pay her back for cab fare and bring her cookies. Upon finding out Banri needs money, Nana invites him to be a waiter at a weekend party. She also insists he bring Mitsuo with him. Mitsuo resists the idea until the Tea Club tries to recruit them for questionable employment. On the night of the party Banri tells Mitsuo that Kōko had wanted to come over, but that he told her he had to work on a report. At the party, Banri finds himself dressed as a maid. The party host offers Mitsuo an extra 10,000 yen to wear nothing but a flesh-colored Speedo, which he accepts.

Banri gets to his feet and tells her to pretend that they are just strangers, as he wants to cut ties with the past. Linda realizes that Kōko is bothered by her being a part of his past life and says she understands and that they are doing the right thing. She then rips the picture into pieces, surprising Banri.
