Light Novel Volume 4.5/Summary

Below is the long summary of volume 4.5 of the You-Zitsu light novel series.

Prologue
The narrator talks about "Sazae-san syndrome", a term about the depressive feeling one can have when realising the next day is Monday, and links the similarity to how the students feel near the end of summer vacation. The narrator disagrees with the feeling as they see the years in school are essentially the only time one is able to freely do what they want, as they will have to spend most of the rest of their life working until retirement after that. The narrator points out how many students have failed to appreciate being a student until later on in their lives.

Chapter 1
Kiyotaka thinks about the matter of making friends, as he has spent his summer vacation without calling or speaking to anyone, stating that he is already satisfied with having his freedom.

After transferring 100,000 points to Ken Sudō, Kiyotaka receives a call from him. Sudō invites Kiyotaka to a fortune-teller in Keyaki Mall. Kiyotaka asks Sudō about his basketball club activities and the recent tournament. He specifically mentions about a certain task. Sudō exclaims it was difficult as the restrictions at the tournament were very high, but he still managed to finish it.

The topic of the call goes back to fortune-telling, with Sudō asking Kiyotaka to invite Suzune Horikita along as well. Kiyotaka, grasping the idea, says he will try but tells Sudō not to expect too much. While slightly disappointed, Kiyotaka then calls Suzune and invite her to the fortune-teller. After discussing about fortune-telling, Suzune refuses to go, saying she is bad at dealing with crowds. Kiyotaka tells Sudō, who also quits from going after receiving the message. Kiyotaka decides to check out the fortune-teller by himself, having been interested in it after his conversation with Suzune.

Kiyotaka arrives at the fortune-teller the next day, only to find out that it is for couples only and a partner is required. While leaving, he notices Mio Ibuki, who has also come alone, and their eyes meet. Ibuki chases after Kiyotaka and inquires him about Suzune, who is not present. They talk about the island exam's result, with Ibuki asking Kiyotaka about D-Class's leader, and he gives a vague answer. Kiyotaka wonders why Ibuki couldn't simply invite a classmate to come along, and finds out about her fondness for fortune-telling, as well as her inability to socialise with others. After talking about the matter for a while, both decide to leave the place as it is seemingly impossible to get in individually. When returning back to his room, Kiyotaka looks into a fortune-telling method after hearing Ibuki mentions about it.

Kiyotaka and Ibuki coincidentally meet again on the next day at the same place. After talking about fortune-telling for a bit, Kiyotaka makes a proposal for them to go together as a pair, and Ibuki accepts after some hesitations. After spending a long time waiting, they get in and proceed to get their fortunes told. While both receive rather generic results, Kiyotaka is said to have a rough childhood with misfortunes, and that he must decide what to do with his life from then on. When the session is done, they are also told to go back straight after leaving, without taking any detours.

While heading back, they decide to take a detour to a different elevator as the usual one is crowded, as well as to find out how accurate the prediction is. The elevator they take proceeds to comes to a halt and they get stuck inside. Kiyotaka tries the emergency button but there is no response. The emergency contact number in the elevator is also painted over. Before his phone's battery dies, Kiyotaka manages to call a certain someone for help. The air-conditioner then stops working and after 30 minutes, both begin to suffer from heatstroke. They try to open the emergency hatch to no avail, with Kiyotaka trying to prevent Ibuki from kicking it. They then try some button combinations, and after some attempts the elevator finally moves. Two adults check on them when the elevator arrives, before Kōhei Katsuragi, the one Kiyotaka has called, approaches them. Kiyotaka expresses his gratitude, while Katsuragi claims it is just a favour after being helped by him and Sudō.

Chapter 2
A week before the events in chapter 1, Kiyotaka is informed about a plan to hold a birthday event for Kokoro Inogashira, a classmate in D-Class. The Idiot Trio want to prepare presents, but since they are running low on money, Kiyotaka suggests to pool their points and buy one present for Inogashira.

Kiyotaka and the idiot trio, without Sudō, go out to look for a present, with Kiyotaka thinking of how inexperienced he is when it comes to this. When Kanji Ike is checking out the keychains, Haruki Yamauchi asks if it is for Satsuki Shinohara and whether Ike is thinking of her. Ike profusely denies and goes on to insult Shinohara, calling her ugly. Kiyotaka and Yamauchi notice Shinohara appears behind and try to warn Ike but unsuccessful. When Ike realises it, he turns around and sees Shinohara along with her friends, including Kikeyō Kushida. Shinohara angrily curses at him and storms off.

Yamauchi then notices Katsuragi's presence in the shop and the three boys start stalking him. They notice him buying a box of chocolates, with Ike and Yamauchi suspecting he has a girlfriend. They then hear Katsuragi talking to the clerk about the chocolates being a birthday gift for someone on August 29.

At night, the usual group gather at Kiyotaka's room, with the topic being about Katsuragi. Kushida mentions she doesn't know of any girl with the same birth date as above. She also scolds Ike for calling Katsuragi a baldie, explaining that he suffered from an illness with that as a result, and for what happened with Shinohara earlier, forcing him to apologise. While the group discuss about the possible candidate for Katsuragi's present, Sudō asks Kiyotaka for Suzune's birthday. Kushida replies it's on February 15, which impresses Kiyotaka as he himself also doesn't know. Kiyotaka wants them not to interfere more in the matter, but the idiot trio refuse, before forcing him to investigate it.

The following day, Kiyotaka starts looking for Katsuragi, whom he has noticed to have his uniform on despite of the summer heat. Before Katsuragi arrives, Kiyotaka bumps into the Student Council President Manabu Horikita, along with his secretary Akane Tachibana. After some short exchanges, Manabu talks with Kiyotaka about the uninhabited island exam and the special exam on the cruise ship, pointing out Kiyotaka's involvements. Kiyotaka still gives the credits to Suzune, and asks for Manabu not to investigate him further.

Manabu then recites his offer for Kiyotaka to join the student council, this time as the vice-president, which shocks Tachibana. Manabu explains that the council will undergo a massive change, and he wants to protect the rules of the school before it's too late. Kiyotaka hears Tachibana mentions about Nagumo, before continuing to reject Manabu's offer, pointing out that Manabu has no reason to worry about the students after graduating from the school, unless he wants to protect Suzune, his sister. Manabu gives up on persuading Kiyotaka and apologise for taking up his time before leaving.

Katsuragi shows up 30 minutes later and makes his way to the school, which explains his uniform attire. As he cannot follow along in his normal clothing, Kiyotaka goes back to the shop yesterday. Katsuragi unexpectedly appears and asks whether Kiyotaka is buying a present for his girlfriend. Kiyotaka denies, explaining it's for his classmate's birthday, then returns the question to Katsuragi. On being asked about his uniform, Katsuragi answers that he has been going to the school for some matter. He talks to Kiyotaka about the school's "No contact with the outside" rule being a disadvantage. After some further exchanges, Kiyotaka asks about the recipient for the present, to which Katsuragi replies it's a personal matter.

Kiyotaka reports back his investigation, stating he still doesn't know who Katsuragi will give his present to. Ike and Yamauchi suspect that Katsuragi buys the present for himself, and start feeling sympathy for him. They then decide to give him a birthday present. Kiyotaka feels unsure about their conclusion, but he chooses not to refuse.

The next day, Kiyotaka, Ike, Yamauchi, as well as Kushida go out to look for a present for Katsuragi. While on the way, Kiyotaka spots Suzune outside and makes an excuse to leave the group before approaching her. They talk about the current situation of their class, with Suzune feeling restless after Kakeru Ryūen's victory in the last exam, while Kiyotaka tells her to take things slowly without rushing. After a short chat, he leaves to go back to his group.

Katsuragi is suddenly surrounded by Ike and the group, and cannot hide his surprise. After he confirms that it's his birthday, Kushida says they want to celebrate it with him. Katsuragi puts his guard up, saying they are not close friends and asking if there is any ulterior motives behind it, before excusing himself as he has his own business at the school to take care of. Ike and Kiyotaka point out about his uniform and the same birthday present bag he has been carrying around. Katsuragi explains he has been going to see the student council to no avail. He then notices Kiyotaka having some connections to the council, with Suzune being the president's sister, and request Kiyotaka to accompany him. Kiyotaka agrees, as he also needs to see the council, having been wearing his uniform.

At the student council room, Katsuragi voices his request to deliver a package and message to his family outside of the school, but Manabu flatly denies. Manabu clarifies that package shipping is prohibited after students were found to hid letters in them without permission. Katsuragi still insists he can have the shop deliver it and will go as far as paying his points for it. Manabu asks about the recipient, and Katsuragi confesses it's for his twin sister, and he is the only one to celebrate her birthday. However, Manabu still turns down his request as the rules are upheld. Dejected, Katsuragi quietly leaves, while Kiyotaka stays behind. Kiyotaka tries to back up Katsuragi, pointing out that it would be fine to break the regulations as long as the school doesn't know about it. Manabu says Katsuragi should have realised that. As Kiyotaka starts heading back, Manabu tells him he will not be involved in this matter, so Kiyotaka can do what he pleases.

When Kiyotaka returns to the dormitory lobby, Katsuragi is waiting for him. He apologises for having Kiyotaka accompanying him, then hands the present bag to Kiyotaka, having given up on delivering it to his sister. Kiyotaka tells Katsuragi there is a way to do so by disregarding the rules. They head to Kiyotaka's room to discuss about it. Kiyotaka explains that while students are forbidden from leaving the school grounds, there are exceptions for club tournaments, and Katsuragi quickly understands.

An hour later, Kiyotaka calls Sudō to his room to ask for his cooperation, since he has a tournament with his basketball club soon. Sudō at first rejects the idea, but begins to consider after Katsuragi proposes a reward for payments. He describes all the checks the school performs, mentioning that the club members can bring their own food. Kiyotaka then gives Sudō a lunchbox and a water bottle, with the gift box and the bag hidden in them, and tells him to mail them through a post when he has the chance.

Katsuragi bows his head and asks Sudō for the favour, telling him he will pay 100,000 points. A stiffened Sudō asks for his reasoning, and Katsuragi reveals that his sister is sick, and as their parents and grandparents have already passed away, Katsuragi is the only one that can celebrate her birthday. To clear their doubt, he will pay 20,000 points in advance. Katsuragi also asks Kiyotaka to hand Sudō his phone, so he can record the proof of the present being delivered, as Sudō's phone will be confiscated. Kiyotaka agrees but says he will use someone else's phone instead, since Katsuragi's points will be transferred to his phone for insurance.

Later on, Sudō successfully manages to deliver the package, having recorded the proof for Katsuragi and deleted the data right after. Kiyotaka wonders whether Manabu might have been involved as well.

After leaving Kiyotaka's room, Katsuragi heads back to his room, only to find Ike and Yamauchi standing in front of it. They then surprise him with a birthday celebration, forcing a cake box to his hands before quickly leaving. A confused Katsuragi opens the box to find a chocolate birthday cake that has already cooled down and become muddy.

Chapter 3
The school sends a mail informing the students, that the water won't work for some days, but they could get 2 litres for free from the cafeteria so it got crowded. The convenience stores were also down, but the Keyaki mall would provide free water, but wasn't allowed to take it back.

Horikita strangely calls Ayanokōji, when she usually texts if she reaches out. After calling her back a few times, he gets another call while his making dinner. He tries texting her but is left on read. He tries again and finally gets through after 4 tries. During the call, he hears a metallic thunk and notices that she's tired before she hangs up.

At 9:00 PM, she calls him again. After vaguely telling her situation, she with a disgusted tone asked him to come over. He enters her dorm and notices, that she too hasn't decorated much. He enters her room and sees a Horikita with her hand stuck in a water bottle. He then goes to the cafeteria and a vending machine to get water, but both are out.

After discussing their options, they conclude it's best to get water from Sakura. Horikita also suspects Kushida for having betrayed them in the Zodiac Exam, but Ayanokōji argues it was also her fault.

Since Sakura didn't answer, they decide to head to Keyaki mall to get water. Horikita objects to using the elevator. On their way to the stairs, they're spotted by Kushida. When they arrived at the East staircase the door was locked. Kushida comes and suggest using the West staircase, and points out Horikita acting weird, but then offers water. Horikita signals, that she doesn't want it and they leave.

They get to the lobby, but Horikita chickens out after seeing a lot of people. They hurry into an elevator, with Ayanokōji covering Horikita from the camera. While going up, the door stops at the 5th floor and Kouenji enters and goes directly to the mirror. He then calls Ayanokōji an elevator boy and tells him to go to the top floor. He didn't look at them once. Sakura texts Ayanokōji back saying she has water and the incident is resolved.

Chapter 4
Yamauchi asked Ayanokōji for help on confessing to Sakura. Ayanokōji proof-reads the confession-letter and hands it to Sakura behind the school building while Yamauchi nervously observes her reaction from afar. Sakura feels faint realising the love letter is from Yamauchi. She leaves before reading the letter but promises to meet Yamauchi tomorrow at the same location. Sakura asked Ayanokōji to also be present for tomorrow's meetup.

Before the answer, Ayanokōji and Sakura meet. Ayanokōji encourages her to be brave as he attempts to leave so as not to interfere, Sakura asks him to stay as she won't be able to say anything if he isn't around. Although Yamauchi is a little bothered by his presence, when Ayanokōji tells him Sakura wants him to be there he cannot say anything to retort. Sakura rejects Yamauchi and leaves the 2 guys alone. Yamauchi apologises for involving him in his business but Ayanokōji says it's not a problem.

Chapter 5
Ayanokōji, Horikita, Ike, Sudou, Yamauchi, Kushida, and Sakura go to the swimming pool. The idiot trio plan to peep at the girls and force Ayanokōji to join. Nagumo attracts lots of attention when showing off his volleyball skills, causing jealousy among the three idiots. They met Ichinose and Kanzaki and play against them in volleyball and win a free lunch/dinner. Ayanokōji suspects it was to scout their ability. The idiot trio's plan unexpectedly fails because Ayanokōji got Karuizawa to interfere. Ayanokōji told Karuizawa he might try to expel someone soon enough before they play around in the pool a little.
