Shuchiin Academy is a beacon for talented students with a bright future ahead of them. The vice-president of 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, so all they do is think about how to get the other person to confess their love. Six months pass without anything happening between them, but then one day, the secretary, Chika Fujiwara, comes in with news about how she won a pair of free tickets to see a movie, a movie that supposedly turns males and females who see it together into romantic couples. This is the trigger that kicks off the romantic game of wits...

The students at Shuchiin Academy are under the impression that Shirogane is a veteran when it comes to romantic affairs, and so it is that despite the fact that Shirogane actually has no romantic experience whatsoever, a male student comes to him seeking advice on a matter of the heart. But if the truth about Shirogane's lack of experience got out, he would lose his dignity as the president of student council. So he nervously takes on the student's request with false bravado: "If it's about love, leave it to me!" Kaguya finds herself in a position to surreptitiously eavesdrop and does so as a chance to hear Shirogane's views on love, but finds his advice off the wall...

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?”

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.

What do Shuchiin Academy's model students do outside of their student council duties? These eccentric activities reveal a side of the student council that has never been seen before!

While all the classes were consumed in preparation for Shuchiin Academy's Hoshin Culture Festival, Shirogane and those from Class 2-B were working hard at making balloon art. As Fujiwara delicately puts finishing touches on a cute balloon bear, the clumsy Shirogane keeps popping them no matter how many times he tries. The sound of balloons popping echoes sadly in the classroom. But Fujiwara, who has joined Shirogane's special training many times up until now, hardens her heart and decides not to help this time. To overcome this without the help of others, Shirogane heads to the student council room for practice. However, Kaguya is in the room...

One week after enrolling in Shuchiin Academy as a special scholarship student, Shirogane had already regretted that he had come to a school he should not have. The students around him were elites born into famous families. Shirogane, who is from a modest household and enrolled from a school outside of Shuchiin's track, couldn't even find a friend to eat with, so he quietly kills time away from the cafeteria. Just as Shirogane's miserable emotions explode, an upperclassman with a student cap appears in front of him. A shining golden fourragere lays across his chest as proof of student council president. And he says that he's come to recruit Shirogane into the student council.

Ishigami, who succeeded in inviting Tsubame on a Culture Festival date, browses around campus exhibits in an attempt to shorten the distance between the two. In the end, it didn't go as well as hoped. But when he tried to express his everyday feelings of gratitude for the upperclassman he feels indebted to, it caused an unexpected uproar. Shirogane was astonished after witnessing the unexpected event. Gripped by the fear that his secretly planned "Make Shinomiya Confess Plan" will be ruined, he sinks into despair after thinking too hard about every detail.

Invited to walk around the culture festival together by Shirogane, Kaguya is unable to hide her surprise at this sudden plot twist. She lightly joked that maybe he was affected by the festival's atmosphere, but Shirogane never dropped his serious expression. Compelled by such intensity, Kaguya decided to walk around the school together. Everyone around them gossips that they are on a date as Kaguya blushes. But while they enjoy visiting a love fortune-teller, food shops and live music, Kaguya feels true happiness. From the depths of her heart, she wishes that each day could continue just like this.

The moment the culture festival reached its finale, the jewel object made by Shirogane was stolen by a phantom thief who calls himself Arsène. Kaguya and the others headed to the roof where the phantom thief keeps appearing, but there was no one there. Fujiwara, who transformed into a genius detective, struggles to solve the mystery behind the calling card and uncover the thief's true identity. But Kaguya, left behind at the scene of the crime, had begun to figure out the criminal. The problem is the location. Kaguya traced the phantom thief's line of thinking and headed to where he is now...

Shroud in a cape and dressed in the guise of the phantom thief Arsène, Shirogane waited for Kaguya's arrival atop the clock tower roof overlooking Shuchiin. When asked why he would do such a thing, Shirogane answered that there was something he wanted to show Kaguya. The festival's afterparty has already begun as the sun set over this school and the students could be seen encircling and enjoying the bonfire. While the emotions that could not be expressed with words mingled between Shirogane and Kaguya's hearts... Shirogane carried out his ultra-romantic operation!!
