As term-end exams approach, the psychological war between Kaguya and Shirogane in the student council room ramps up. Kaguya is an all-around genius, but her pride is hurt because she hasn't yet beaten Shirogane when it comes to academics. Meanwhile, when it comes to making an effort, Shirogane is second to no one and as the president of student council, he refuses to let anyone else usurp his position at the head of the class. The two of them lie through their teeth and employ wiles worthy of Machiavelli in an attempt to get ahead of the other. At last, it's the day of finals, but which of them will the goddess of victory smile upon?

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-synching 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 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.

After their second semester final exams end, there are plans for a sleepover at Kaguya's house. But Shirogane and the others are unable to come, leaving Fujiwara as the only one who can join. While barley glancing at an upset Kaguya, Fujiwara gets excited about the totally hot butler Mr. Herthaka without realizing it's Hayasaka dressed as a man. That night as the girl talk unfolds at the pajama party, a sleep-deprived Kaguya takes on a strange mood before anyone can notice. With that energy, she calls Shirogane and ends up asking outrageous questions.
