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. While waiting on party-goers, Banri sees that Linda is also working at the party dressed as a devil girl. Meanwhile, Kōko is unable to contact Banri as he is not carrying his phone with him at the party.

Banri Tada is enjoying working as a waiter at the party, along with Nana, Mitsuo and Linda. Meanwhile, Kōko has texted Banri numerous times and is becoming concerned that he hasn't answered. Some of the guests see Banri and Linda together and insist on taking their picture. The two of them get carried away and strike several provocative poses just as Kōko, who has come looking for Banri, arrives. Incensed, she throws a drink in Banri's face and slaps him. Linda tries to apologize but Nana stops her and Banri takes Kōko away to the fitting room. Unable to talk for long as he is still on the job, he gives her the key to his place and tells her to wait for him there. Kōko leaves and Banri continues working but is concerned about his relationship. Once the party is over and they receive their pay Banri tells Mitsuo that his salary might have lost its usefulness. On his way home Banri checks his phone and is shocked to discover that Kōko has been texting him all day. He hurries home to a dark apartment and is relieved to find Kōko waiting for him. The couple apologize to one another and Kōko returns the picture of Banri and Linda, much to his surprise. He admits that they were former classmates and he had been in love with her. He then goes on to tell Kōko that his feelings for Linda return sometimes in flashes. Kōko hugs him in response and says that all she want is for Banri not to remember the past, with Banri understanding and so the couple reconcile. The next morning, Banri tells Linda that he wants to talk with her. Beside the river, he asks if she loved the old Banri; she replies that she only thought of him as a friend. Banri then tries to rip the picture of them together, with the ghost of the old Banri looking on and saying no. He drops the picture, which Linda then picks up. 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. The next morning, Kōko and Banri take a picture together, forming new memories for just the two of them.
