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 Kikyō 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 to 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 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. He 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 dormitories receive news that water will not be accessible for a while. Students are informed by the school that they can get some water at the cafeteria when needed, 2 litres at a time. The school also warns about the place being crowded, and nearby convenience stores are closed as a precaution. Students can use the water in Keyaki Mall but are not allowed to bottle it for themselves.

Kiyotaka strangely receives calls from Suzune, who usually texts if she reaches out. Before he can answer it, the call gets cut off. After calling her back a few times without getting a reply, he gets another call while making dinner, again with the same result. Kiyotaka tries texting her but is left on read, so he decides to go back to cooking. Later on that night, Kiyotaka decides to text Suzune again, but his message is not even shown as read. Getting worried, he tries to call her 4 times before she finally picks up. Kiyotaka asks if something is wrong but she denies and apologises to him for not answering his calls. As Suzune tells him she is busy, Kiyotaka hears a metallic thunk. She claims it's nothing before ending the call.

At 9:00 PM, Suzune texts him again, this time wanting to talk with him for a bit, and Kiyotaka calls her back. After vaguely telling her situation and trying to push aside the matter, Suzune finally admits she is in trouble and asks him to come over, with a frustrated tone. After sneaking up to her dorms room, Kiyotaka presses the chime but the door stays closed. He tries opening it and finds out it's not locked. After entering her room, Kiyotaka sees Suzune, who slowly appears and reveals that her right hand has been stuck inside a small water bottle.

Suzune explains that she was washing it, and hurries Kiyotaka to help her take it off. After unsuccessful attempts, Kiyotaka decides to head off to the cafeteria so he can get some water to help. To his dismay, due to high demand, the cafeteria has run out of water, and the vending machine nearby is completely emptied. Kiyotaka has used up his own share of water, while Suzune turns down his suggestion of borrowing from Ike or Yamauchi. After more unsuccessful attempts to pull out the bottle, Kiyotaka tries to call Yōsuke Hirata but there is no response as it's already late at night.

The only options remain are Kushida and Airi Sakura, and Suzune immediately asks for the latter. She mentions how Kushida's actions have been suspicious during the cruise ship special exam, but Kiyotaka argues that Suzune is mainly responsible for their loss in the exam. She admits it before turning her focus back on the stuck bottle. Kiyotaka sends a message to Sakura but it does not appear to be read. He convinces Suzune to go to the Keyaki Mall as the last option. They consider using something to hide the bottle, but eventually decide not to.

Both start heading out of the dorms to Keyaki Mall. Suzune objects to using the elevator as surveillance camera is installed. On their way to the emergency stairs, they are spotted by Kushida, who is returning from Maezono's room. They try to use the East staircase but the door is locked. Kushida comes and suggest using the West staircase. She points out Suzune is acting weird, but then offers water. Suzune signals to Kiyotaka that she doesn't want it and they leave.

They get to the lobby, but after seeing a lot of people, Suzune wants to go back. Since they cannot use the emergency stairs as someone is descending, they hurry into an elevator, with Kiyotaka covering Suzune from the camera. While going up, the door stops at the 5th floor. Rokusuke Kōenji enters and goes directly to the mirror to comb his hair, without glancing at them once. He then requests to go to the top floor, referring to Kiyotaka as elevator boy. After getting out of the elevator and going back to Suzune's room, Kiyotaka receives a message from Sakura, notifying him that she can share her water. Kiyotaka says he will go to her place in response, while Suzune asks him not to tell Sakura about her as he is leaving.

Finally, after getting the water, they manage to pull the bottle off Suzune's hand. She warns him not to mention the ordeal to anyone, but Kiyotaka reminds her to say something first. Suzune begrudgingly lets out a small 'thank you', before urging him to leave. After returning to his room, Kiyotaka wonders if it's possible to get stuck like that. He takes out the water bottle and puts his hand in to test. After playing around, he tries to take it off, but realises that his hand has been stuck as well.

Chapter 4
Yamauchi asked Ayanokōji for help on confessing to Sakura. Ayanokōji reluctantly decides to help him after Yamauchi brought up how he was made a fool of by him as well as lied to when he promised to give Sakura's number. Ayanokōji proof-reads the confession-letter, remarking to himself that it seems overly formal and rudimentary. The last paragraph greatly worries him as he promised to give her all his private points if they could date. Nonetheless, he decides to hand it to Sakura behind the school building while Yamauchi nervously observes her reaction from afar. Sakura felt giddy after misinterpreting that the love letter came from Ayanokōji. She then asked for his advice when dealing with this letter. Ayanokōji attempts to leave but Sakura grabbed him before he does so, asking if they could read it together. Trying to be respectful to the original sender, he refuse to comply but tried to assure her by saying that it might be from someone she fancy. She rejects that notion by saying that it is not possible now. She then decides to leave and read the letter in her room.

In the middle of the night, Sakura texted Ayanokōji and asked if they could meet up prior to her scheduled meeting with Yamauchi tomorrow at the same location. She then voices her dilemmas to Ayanokōji and apologised for burdening him which he replied saying that he would help her if it's within his abilities. She then asked if Ayanokōji had a girlfriend which he denied saying that he has never dated anyone. Ayanokōji was perplexed by her seemingly joyful reaction as they chatted until Sakura got tired and went to bed.

Before her 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 that Sakura wants him to be there, he could not say anything as a retort. Sakura then rejects Yamauchi and running away and leaving the 2 guys alone. Yamauchi apologises for involving him in his business but Ayanokōji says it's not a problem. The silver lining was that Yamauchi found out that he wasn’t as interested in Sakura as he first thought.

Chapter 5
Ayanokōji, Horikita, Ike, Sudou, Yamauchi, Kushida, and Sakura go to the swimming pool. The idiot trio plans 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 tells Karuizawa that he might try to expel someone soon enough before they play around in the pool.
