The film begins with Kako Motoya, a 16-year-old high schooler, hurrying to a tram stop, where her best friend, Mikado Yaguchi, is waiting for her. The two are on their way to a singles' mixer, to which they had been invited to last minute by Mikado's older sister, as the eve was short on two girls. Arriving at a bar, the girls are greeted by Mikado's sister and her sister's friend, who instruct the girls to pretend to be 22-year-old college students, not to drink and not to hog all the men to themselves. It is first now that Kako finds out that the event is adults-only, and panics a little at the thought of attending. Despite this, the girls head on inside and attendees. It does not take long before the girls are already in trouble, as they almost get pressured into drinking by two men, who consider their soberness a waste of free alcohol. However, the girls are saved by Kota Sagano, who offers to take the shots the men had poured for the girls, and then disappears as quickly as he had appeared, followed by the two men, who are both disappointed that the girls did not drink and impressed by Kota downing two strong shots at once.

After the party, Mikado has to take her drunk sister home, leaving Kako alone. Kako takes this opportunity to thank Kota for helping her, and the two end up going home together, having to run as they are almost late for the last tram of the night. During this time, they are almost separated in a crowd, and end up holding hands the rest of the way. Despite their best attempt at hurrying, they end up missing the tram and have to walk. The atmosphere between them is chummy until Kako accidentally reveals her real age of 16, at which point Kota angrily scolds her for her recklessness. The two separate, but not for long, as Kako takes a detour through a side alley and gets harassed by a group of delinquents, one of whom is Heisuke Okami. Kako recognises him, but he does nothing to help her. Instead, Kota finds them and stops them from bothering Kako any further, however, Kako gets hurt in the process, as she runs up to shield Kota from Heisuke, who was about to hit him with a skateboard. The police arrive to arrest the delinquents while Kota calls an ambulance. At the hospital, Kota apologizes to Kako's parents, who do not blame him for what happened. After they leave, Kota goes back to Kako's hospital room, where she wakes up. The two share a heartfelt conversation which ends with Kota proposing to Kako.

Mikado is happy to see Kako back in school, and there with her to greet Kako is an excited Jiro Nagakura. Kako does not yet reveal to either one of her dear friends that she has been proposed to. While Kako's mother is accepting of the proposal, Kako's father is against her daughter getting married to an adult man at such a young age. Regardless, he accepts once he sees how serious Kota seems to be about the relationship. Later, Kota proposes to Kako properly, offering her an engagement ring, which Kako proceeds to wear as a necklace to hide her engagement from her schoolmates. She does, however, reveal the truth to Mikado, who has a hard time believing her ears, noting that even if she wanted to gossip about the matter, no one would believe her.

At school, Kako and her friends run into Heisuke, and are all slightly freaked out to see him- Jiro and Mikado quickly proceed drag Kako away from him, not wanting the two to interact. Kako, however, is reluctant to leave, sharing a brief glance at one another with Heisuke before the latter walks into class and the former is pulled away by her friends. Later on in class, Jiro points out to Kako that Heisuke is staring at her. After school, Kako goes to visit the police box, only to find Kota absent and Shuichi Yamamoto there instead. The two share a friendly conversation, during which he shows Kako a photo of young Kota, which she proceeds to take a picture of and put as her phone wallpaper. Yamamoto also ends up revealing that Kota's father died when Kota was a teenager.

Later, when shopping for cooking ingredients, Kako runs into a pink teddy bear handing out tissues. This bear turns out to be Heisuke, who is working one of his part-time jobs. Reluctantly, Kako ends up talking to him, and he apologizes to her sincerely. Kako accepts his apology, seeing that he is much more kind and compassionate than he seems. When Heisuke leaves to get more tissues, Kako sees Kota with another woman, and assuming that the two are on a date, borrows the head of Heisuke's teddy bear costume and tails the two. Kota and the woman, Fumi Komori, end up being just co-workers on their way to a work related event, and just when the two are about to leave, Heisuke returns to Kako, only to be greeted coldly by Kota. The two almost break into a fight, but are stopped by Fumi. Kako tries to stand up for Heisuke, saying he had not done anything wrong, but gets shut down by Fumi, who says it is only natural to suspect Heisuke and be worried for Kako in this situation. She and Kota leave, while Heisuke and Kako exchange the things they had with them and go their separate ways.

Later that evening, Kako and Kota have a small argument over Kota always acting as if he is on-duty, and not seeing Kako and Heisuke as complex beings. The two get over this argument relatively quickly, as they play a game and apologize to one another, going on about the evening in peace.

Back at school, Kako's class has decided upon their school festival theme, which will be a dress-up booth. Kako tries to talk Heisuke into taking part in the event, but he refuses to, leaving to attend a job interview. There, he runs into Kota and Yamamoto, who stop him and try to find out if something is wrong with his homelife. Heisuke denies this and goes home. There, he almost gets beat up by his mother's seemingly alcoholic boyfriend.

While Kako is visiting Kota to make reference his police uniform for the school festival, the two share a sweet hug which gets interrupted as Kako mentions Kota's high school days to him, and he ends up having a flashback to the time his father got murdered.

Time passes with Kako, Mikado, Jiro and Heisuke, who got dragged into the festival preparations by the group, hanging out together at school, while Kota is busy at work. Without telling about it to his new friends, Heisuke applies to drop out of high school, but Jiro finds out about this. He stops Heisuke from leaving early, dragging him back to the classroom where the friends take a commemorative group picture with one another. Kako has to leave though, for Kota calls her, and is waiting in his car outside the school. The two end up having another small argument related to Kota always acting like a policeman and never truly letting Kako close to him, however, their interaction is cut short when Kota is called in for work. Kako does not return to the classroom, instead crying in the hallway, only to be found by Heisuke, who tries to cheer her up. When Kako tries to shake off her sorrow as nothing, he hugs her upon impulse, surprising the both of them.

Later at home, Heisuke has gotten beaten up by his mother's boyfriend, and the house is a mess. Because of the noise, their neighbours had called the police, who come to investigate, but both Heisuke and his mother's boyfriend claim there is nothing wrong. Kota and Fumi, however, have grown more and more suspicious of the situation, and decide to bring the older man in for questioning. Later, Jiro, Kako and Mikado go to Heisuke's place, and end up helping him clean the apartment, showing him that they really care for him and consider him a dear friend. This moves Heisuke, and he promises to participate in the school festival the following day. Kota, who had been earlier invited to the festival by Kako, has also come, and Mikado proceeds to force him into dressing up as a high school student to blend in. Kako then drags Kota on a date around the school building, and the two end up having loads of fun before Kota spots a collegue, and the pair end up hiding in a vacant classroom. They almost kiss, but get interrupted by students trying to come into the classroom. This is just about enough excitement for Kota, as after the students leave, he and Kako return to Kako's classroom, but stumble upon Heisuke. While Kako goes to change, Heisuke and Kota end bickering with one another in a relatively friendly way. However, once Kako has finished changing and heads out to buy takoyaki with Heisuke, the latter is reminded of a time when Kako accidentally dropped her phone, and he saw her wallpaper, finding out that Kako has a boyfriend. He notices that this boyfriend looks an awful lot like Kota in his school boy outfit, but does not get to comment on it before Kako has already dragged him away. While away from the classroom, Heisuke and Kako end up talking more about her suppossed boyfriend, and are simultaneously spotted by Heisuke's old delinquent friends, who assume that Heisuke and Kako are dating. Returning to the classroom alone, Heisuke questions Kota about a funny looking little brother, which confuses Kota, who only has an older sister. This is when the two spot the delinquents harassing Kako, and they rush out to help her, only to find that she has been taken. Heisuke tells Kota where the group are going and why he assumes they took Kako, and the pair end up following the delinquents together.

Whilst saving Kako, Kota ends up shielding her from one of the delinquents, and gets stabbed in the process. Kako is left terrified in shock, this serving as the final straw that breaks the camel's back for her. At night, she is comforted by Mikado and Jiro on the hospital roof, as they had left the festival once they found out about the incident. While hugging Mikado, Kako blames herself for Kota getting hurt, completely breaking down in Mikado's arms. After Kako has calmed down, the three light up a lantern that Jiro had brought with him, and Mikado urges Kako to make a wish upon it. They release the lantern and it floats away into the night sky.

When Kako is visting, Kota finally wakes up in his hospital bed. The shock of the all the previous events has left Kako so affected, that she ends up breaking off her marriage with Kota, claiming that she does not have the mental strenght to be with him if he is going to keep on being as self-sacrifical as he has shown himself to be.

Much later, Kota goes to visit Heisuke, who is packing up his things and moving out with his mother, who has broken things off with her abusive boyfriend. Heisuke and Kota end up having a civil discussion, during which Heisuke reveals that Kako has seemingly lost her spirit and is faking her emotions around her friends. He also reveals that he knew about Kako and Kota's relationship. When back home, Kota looks at his old marriage papers alongside all the small touches Kako had left in his house throughout their relationships, like stickers covering up a crack in one of the windows. He is reminded of the time after his father's funeral, and the words his sister passed on to him.

Time passes, and the police have been invited to Kako's high school to tell the students about their work. There, Mikado proceeds to ask the officers why they have chosen such a dangerous career, knowing about why Kako and Kota had broken up and wanting to ask an armour piercing question. This leads to Kota offering to answer the question, and while his heartfelt explanation inspires the student body, it also makes Kako cry. Later, Kako tells her friends she is going back, and Mikado and Jiro cheer her on, knowing that she is going to try and get back with Kota. Simultaneously, before leaving, Kota decides to return to the auditorium, leaving behind him a happy Yamamoto and confused Fumi. Kako and Kota almost miss each other, but ultimately end up reuniting and rekindling their marriage.
