A typhoon that shuts down the trains brings good fortune for Kaguya, if only she’d simply use it and not make things more complicated. However, asking Miyuki if he wants a ride, thus initiating a “car date”, would be breaking her code, so she waits for him to ask for a ride instead.
Her hesitation ends up opening other opportunities for Miyuki. First, Chika offers to share her taxi, and Kaguya has to use her fear of lightning stealing her belly button to usher her out of the StuCo office. But then the trains start running when the typhoon dies down, further threatening the car date.
Kaguya resorts to sabotaging Miyuki’s phone battery, but he still doesn’t ask for a ride, and when her phone rings, she panics and runs outside where Hayasaka and the car are waiting.
Still, Kaguya waits outside, in the lashing wind rain, for Miyuki to come outside, get down on his knees, and beg for a ride. Instead, he races out of the school on his bike, resigned to get soaked but intent on getting to work as quickly as possible. He utterly drenches Kaguya in his wake.
The next day, Kaguya has a terrible fever and is consigned to bed. Someone from the StuCo has to visit her to drop off printouts, and Miyuki leaves himself open until Chika brings up the fact Kaguya talks and acts like a baby when she’s sick. Suddenly, Miyuki is motivated to be the one.
But Chika decides they’ll determine who goes with a game of Concentration, and she cheats numerous times, so intent she is on seeing Kaguya in her cutest state. All the time, I was wondering why Miyuki didn’t simply use his authority as president to decree that he was going.
Once he hears from Yuu that Kaguya was waiting outside for someone and starts to remember drenching someone, Miyuki does what he needs to win the card game, while shaming Chika into oblivion; Chika leaves the office the way Yuu usually does: pondering death.
Miyuki arrives to find Hayasaka disguised as a maid, and she escorts him to Kaguya’s room where she’s ransacking the place looking for fireworks. Chika was right: Kaguya isn’t just a baby, but completely off when she’s sick. Hayasaka explains that her ego is being suppressed by the fever, leaving only the id.
She then leaves Miyuki along with Kaguya, making sure to drive into his head the fact that they won’t be disturbed, the walls are soundproof, and Kaguya won’t remember anything he says or does while in her feverish state…BUT tells him not to do anything appropriate, wink-wink.
Miyuki is on his best behavior, but the fever-drunk Kaguya is the one who ends up doing something inappropriate. She opens her covers, pulls Miyuki into the bed, and won’t hear of him leaving her side. Miyuki is exhausted anyway, and so falls asleep.
Kaguya wakes up before him, the fever passed and of sound mind, and completely freaks out when she finds Miyuki beside her. She rouses him from sleep, shoves him out of the bed and her room, and asks a coy Hayasaka “how far she got” with Miyuki while she was feverish.
Thus ends the least romantic first sleepover either Kaguya or Miyuki could have asked for; one in which one of them wasn’t really all there, and the other was rightly very careful not to take advantage. I liked how this entire episode told one continuous story, though I doubt there will be lasting repercussions from the “sleepover” due to the unique circumstances involved.
