The boy who has been dating Kashiwagi, thanks to Shirogane’s help, comes back yet again for more relationship advice from Shirogane. But something seems different about him. With his return from summer vacation, he has completely transformed into a player. Getting advice was just an excuse to brag about his girlfriend to Shirogane and Ishigami, and the two suspect that he has "experienced nirvana." They decide to leave the couple alone and observe them from afar as the two lovebirds start to get into a romantic mood…

Kaguya finally gets to go window shopping and watches vigilantly for her chance to befriend Shirogane’s sister, Kei. While the Fujiwara sisters get in the way, she eventually manages to position herself next to Kei. But then, she can only see Shirogane’s resemblance in Kei’s profile, making her heart beat wildly out of control. Kaguya still decides to take the opportunity to figure out what she should give Shirogane for his birthday when Kei mutters that she isn’t very close to her brother. What secrets will Kei spill about Shirogane?

On their final day as the 67th Student Council at Shuchiin Academy, the four members clean out the Student Council Room where they find many memorable items, one after the other. From the banner used at the French exchange student welcome party, the deck of cards that was used to cheat during Concentration, the cards from the forbidden word game, the cosplay cat ears, the inappropriate magazine that was confiscated from a student, and the movie tickets for Mr. Birdson of Birdville, each of these items bring back fond memories and they can’t stop talking about their time together. And so, the four leave the empty Student Council Room behind…

Shirogane is at the top of the race for the student council elections according to the latest predictions, but he is concerned about Miko Iino, a first-year who is trailing close behind him in the race. His competitive streak flares up when he has a conversation with Miko during her election campaign and finds out that she has been at the top of her class as well as an eloquent speaker. Fujiwara plays the role of the peacemaker while tensions mount between the two rivals, but she is caught off guard when Miko asks, “Will you be my vice president if I’m elected as the student council president?”

No one surpasses Shirogane when it comes to academics, but he has never been very confident with his musical skills and always faked it by lip-syncing whenever they had to sing the school anthem. Though Shirogane’s secret is soon discovered by Fujiwara, if the other students find out that he can’t carry a tune, his reputation as the perfect former student council president would be ruined. Since Fujiwara was able to help Shirogane overcome his lack of athletic skills in the past, she agrees to help him with singing lessons… However, little does she know that Shirogane’s level of tone deafness may be beyond hope!

The fateful day of the student council elections finally arrives, but Miko’s efforts are in vain, and it appears that Shirogane’s past experience as the president has given him the edge to be the projected winner. Kaguya gives a perfect endorsement speech showing that Shirogane and his team are leagues above Miko’s camp. However, for some reason, Ishigami looks troubled. He is worried that Miko, who suffers from stage fright, will be unable to deliver her speech, and become the laughingstock of the whole school. As Ishigami is visibly frustrated by this prospect, Shirogane utters "I just need to win in a way so that Miko Iino won’t be ridiculed by the other students, right?" as he heads for the stage…

Ishigami has a biased opinion that "Guys who wear boxers are all man whores." Kaguya takes his words to heart and is dying to know what kind of underwear Shirogane is wearing. She tries to come up with different strategies so that she can take a peek at his underwear without it seeming weird, but all her ideas are too naughty. She decides to ask him directly what kind of underwear he likes, but Shirogane misunderstands the question and thinks she is asking him what kind of lingerie he is into. Shirogane starts to imagine the kind of underwear that he wants Kaguya to wear.

The newly formed student council welcomes Miko as the auditor, but for some reason the student council room is full of tension. Miko is such a stickler for the rules that if she sees anything that appears remotely inappropriate she frequently ends up harshly berating them.

In an effort to break out of his shell and become a normie, Ishigami decides to join the Cheerleading Squad for the school sports festival, but much to his dismay, the team is essentially the "Tribe of Yay!" While Ishigami feels hesitant, the team meeting intensifies fueled by enthusiasm and zeal, where it is decided that all the boys will dress up in girls’ school uniforms while cheering. However, Ishigami, who is a loner, can’t think of any female friends who would casually lend him a uniform. As he begins to consider quitting the team, Kaguya appears…

Though no one surpasses Shirogane when it comes to academics, his lack of dancing skills finds him in his third intense training session with Fujiwara in preparation for the school sports festival. However, Shirogane is such a hopeless dancer that Fujiwara’s patience runs out and storms out of the room. As Shirogane proceeds to diligently practice on his own, Kaguya appears and starts giving him dance lessons. Fujiwara, who has returned to check on Shirogane, begins to argue with Kaguya about the best way to teach him and so a battle ensues! Who will end up victorious as the better dance teacher?

With the sports festival now in full swing, the performance of the cheerleading squad is a great success, and Ishigami is overcome with a sense of fulfillment that he has never experienced before. However, when a classmate from middle school, Kyoko Otomo, approaches Ishigami, his facial expression completely changes. While still being visibly rattled, he is chosen to replace the injured leader of the cheerleading squad as the anchor for the relay race. As a pale faced Ishigami steps up to the track, he begins to reflect on an incident he once caused in the past at school…

The student council is asked to model for the Shuchiin Academy brochure. However, Kaguya's family has a strict policy prohibiting her from being photographed for any forms of publicity, and as result, she is unable to participate. As Kaguya longingly observes the rooftop photo shoot, the student council members propose to take a final group photo, solely for private use, on their cell phone, which makes Kaguya very happy. Just then a gust of wind blows across the rooftop, causing her to drop her phone and sending it way down below to the school grounds. Kaguya picks up her shattered cell phone from the floor and begins to reflect on all the photos with everyone she has lost, and becomes overwhelmed with sadness.

Shuchiin Academy is a beacon for talented students with a bright future ahead of them. The vice-president of the student council, Kaguya Shinomiya, and the president, Miyuki Shirogane, are attracted to each other, but they are both too proud to be honest about their feelings. As a result, all they do is think about how to get the other person to confess their love. Six months pass without anything happening, when one day, a pair of tickets to “the movie that turns boys and girls who see it together into a couple” won by the secretary, Chika Fujiwara, triggers the cunning battle of love…

The students at Shuchiin Academy are under the impression that Shirogane is an expert in romance too. But in reality, he has no romantic experience whatsoever when a male student comes to him for advice regarding a crush. In a desperate attempt to cover his lack of experience and to protect his dignity as the Student Council President, he takes on the student’s request and claims, “Leave it to me!” For Kaguya, who has been eavesdropping, this becomes an excellent opportunity for her to find out Shirogane’s views on love. But Shirogane’s advice on love seems very absurd…

Fujiwara is startled when she unknowingly flips through the magazine that the principal had confiscated, and comes across a “When was your first time?” survey. The magazine reports that 34% of high school students already have that experience. While Shirogane tries to calm Fujiwara down by affirming that the number is inflated, Kaguya declares, “The percentage sounds accurate to me,” and adds that she’s also already experienced. Shirogane who has never been in a romantic relationship is astounded when he hears this confession. Kaguya seizes the opportunity to attack him with, “Don’t you have a girlfriend?”

Kaguya and Shirogane are somehow roped into cosplaying, when Fujiwara suggests her idea on how to welcome the sister school visiting them from Paris. Deep down, Kaguya does not take this suggestion seriously, but she still tries on the cat ears and sighs out, “meow.” This instance strikes a soft spot of Shirogane, who loves cats. But as adorable as Kaguya looks, Shirogane tries to keep his cool. Meanwhile, Kaguya is just as enchanted when Shirogane also ends up trying on the cat ears. How will today’s battle turn out, as the two fight to cover up their true feelings?

Despite his excellence in academics, Shirogane severely lacks in athletic ability. Which is why he has been tirelessly practicing volleyball after school. With only a week left until they begin playing in class, it all seems hopeless as there are no signs of progress and his image as the perfect Student Council President could soon be tarnished. Just as Shirogane starts losing hope, Fujiwara shows up. Swallowing his pride, he pleads her to coach him, and so Shirogane’s days of training under the intense tutelage of Fujiwara begin. Will his volleyball serve improve to the level of an average person in time?

Yu Ishigami is the fourth member of the Student Council. Despite being a first-year, he was scouted by Shirogane for his expertise and was appointed as treasurer. Because he is introverted, Ishigami often goes unnoticed, but he is also the most indispensable member of the council. Suddenly one day, Ishigami comes to Shirogane to request his resignation. No matter how desperately Shirogane tries to persuade him to stay, he seems to have firmly made up his mind. Apparently, the situation is beyond Ishigami’s control, as he begins to tear up and explains that “he’s likely to get killed…”

Kashiwagi’s boyfriend returns, seeking more romantic advice from Shirogane, while Kaguya yet again attempts to eavesdrop on the two. Shirogane’s advice the first time around successfully brought this couple together, but the boyfriend tells Shirogane that he hasn’t been able to hold hands with Kashiwagi after a month of dating. Kaguya is dumbfounded when she hears him ask, “How can I hold hands with her?” but Shirogane is relieved by this simple question that seems manageable even for someone with no experience in romantic relationships. However, Shirogane’s advice seems to once again take an unexpected turn and…

As final exams approach, the psychological war between Kaguya and Shirogane intensifies within the Student Council Office. Kaguya is an all-around genius with her pride at stake but she has never been able to surpass Shirogane in academics. On the other hand, Shirogane is a genius through hard work, who won’t allow anyone to take his position at the top of the class. In an attempt to get ahead of the other, the two lie through their teeth and it becomes a battle of finesse. At last, it’s the day of finals, but which of them will the goddess of victory smile upon?

Kaguya is sick at home, and a teacher has asked Shirogane to deliver her assignments to her house. When Shirogane tells the rest of the council members, Fujiwara excitedly volunteers to go in his stead. According to Fujiwara, Kaguya becomes needy when she is sick. Shirogane’s heart beats fast as he imagines this cute Kaguya, but the entire Student Council couldn’t possibly barge in on Kaguya when she is sick. And so, Fujiwara proposes playing a game of concentration to decide on who will visit Kaguya. Even Ishigami is dragged into what becomes a heated battle!

Kaguya and Shirogane have seemingly reconciled after their fight from Shirogane’s visit when Kaguya was sick. However, resentments linger, ready to explode at any moment. Kaguya decides to consult Kashiwagi since she has a boyfriend and tells her that she is “asking for a friend.” Meanwhile, Shirogane asks Ishigami, who watches a lot of romantic comedy, about how to make up with a girl after a fight, but Ishigami ends up getting heated… As Kaguya and Shirogane get advice, the two slowly begin to realize how they truly feel about each other.

Half a month into their summer vacation, Kaguya spends her days moping around, unable to see Shirogane without the Student Council meetings. However, the Student Council members are planning on going to see the fireworks together at the end of the break. Due to her strict upbringing as the daughter of the head of a conglomerate, Kaguya has had no memorable summer experience and has been looking forward to the day she gets to see everyone. That is until…

After being forced to abandon seeing fireworks with her fellow Student Council members, Kaguya shuts herself up in her dark bedroom. Hayasaka, Kaguya’s maid, is worried about her mistress’s depressive state. She tries to cheer Kaguya up and when that doesn’t work, introduces a plan to sneak out of the family mansion. Kaguya manages to slip past a pair of vigilant butlers and reaches the venue, but the fireworks display is already over. Kaguya is in tears, since she really wanted to see the fireworks with the others, but then she hears a familiar voice: “Then, I’ll show them to you.”
