Banri Tada, a freshman law student at a Tokyo university ended up arriving late for his entrance ceremony. Not knowing how to get to the university, he discreetly followed two other students, and meets Mitsuo Yanagisawa, another freshman, who quickly befriended him. As they made their way to their orientation, they were greeted by a beautiful young woman, who presented Mitsuo with a bouquet of roses and then proceeded to smack him with them before leaving. Mitsuo later explained that the woman was Kouko Kaga, his childhood friend, and arranged fiancé, whom he had run away from as he does not reciprocate her feelings. After orientation, Banri and Mitsuo learn that Kouko was also a student at their university, much to Mitsuo's horror. She became acquainted with Banri during a shared class, and he soon became smitten. After class, Banri met and befriended freshman Chinami Oka and Linda, a second year student and member of the Japanese Festival Culture Research Club. On his way home, he once again runs into Kouko, who used his phone to locate Mitsuo, but upon returning it, he noticed the phone number for a hospital, causing him to remember a time when he was on a bridge and was seemingly run over by a motorbike.

Banri has a dream of himself, apparently injured, fleeing from a hospital, but upon awakening cannot remember any more than that. Arriving at the university gate, he meets Kouko, who is waiting for Mitsuo, and the two talk some more. He notices that Kouko seems lonely without Mitsuo. Later that night, he tells Mitsuo about Kouko, but Mitsuo brushes it off, saying Kouko is just acting to get Banri to bring her to him. To brighten the mood, Mitsuo invites Banri to the Film Club's welcoming party, where club member Chinami got Mitsuo to join. The party was soon crashed however by the Tea Club's party, who drag Banri off to join in their festivities. He meets a new friend Takaya Satō, nicknamed Nijigen. The next day, Banri notices that Kouko has still not made any friends, and encourages her to join a club. Another student overhears them and invites the two to a café to tell them about her club, which lasts until dark. She invites them on her club's overnight trip to see if they would be willing to join. Still wanting to help Kouko, Banri decides to accompany Kouko when she agrees to go.

In a dream, Banri remembers that after his love confession to Linda, she agreed to tell him her response the following night on the bridge where Banri would have his accident. Kōko notices Banri's unusual behavior around Linda, but when she questions him, he denies that anything is wrong. Chinami finds the two and invites them to a party, but Kōko declines out of dislike for Chinami, but this does not dissuade Chinami, who explains to Banri that she likes Kōko. Banri convinces Kōko to attend, alongside Mitsuo and Nijigen, but Kōko and Mitsuo end up arguing about Chinami, which ends with Mitsuo confessing to Chinami, and her turning him down. On their way home, Banri decides to end his friendship with Kōko, due to her lasting infatuation for Mitsuo, and despite Kōko's objections, he leaves her. The next day, Linda notices the tense atmosphere between the two, but when she inquires about it, Banri confronts her about not telling him that they previously knew each other. Linda explains that she said nothing out of fear of confusing him and driving him away, while also admitting her guilt in feeling that she had caused Banri's accident by not responding to his confession sooner. Afterwards, Kōko meets up with Banri to learn what happened, but he takes off running due to the revelation that Linda might have reciprocated his feelings years ago, and how her answer would have affected his life. Before he can wonder if having the same accident would let him do things over again, Kōko manages to catch up to Banri and tells him not leave her, confessing that she loves him.

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.
