After being forced to bail out on 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."

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.
