For some reason, Kaguya and Shirogane indulge Fujiwara's idea of doing cosplay for the upcoming gathering with students from their sister school in Paris. Deep down, Kaguya thinks it's silly, but when she puts on cat ears, a subdued "meow" escapes her mouth. Moreover, that minor cosplay is an unexpected major hit with Shirogane, an avowed cat lover. He's so bowled over by her cuteness that he isn't able to maintain his usual presence of mind. The situation becomes more complicated when Shirogane follows suit and puts on cat ears, which secretly thrills Kaguya. Unable to hide their thoughts that each other looks cute, the two act weirder and weirder...

When Kaguya stays home from school with a cold, Shirogane tells the other council members that he's going to drop off handouts at her house, an announcement that stirs Fujiwara up as she volunteers to go in his stead. According to Fujiwara, Kaguya acts like a baby when she gets a cold. Shirogane's heart beats fast as he imagines a cute Kaguya who's upfront about what she wants, but he shoots down the idea of all the student council members barging in on Kaguya when she's sick. So, Fujiwara proposes playing a game of Concentration to decide on who will visit Kaguya. Even Ishigami gets dragged into what becomes a serious battle!

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?

Kaguya makes a big fuss when she learns that Shirogane was invited to a karaoke group date and orders Hayasaka to remove him from the venue. Dissatisfied with such treatment yet unable to refuse her mistress' instructions, Hayasaka joins the party as Shirogane's acquaintance Smithee A. Herthaka and plans to ruin the atmosphere by airing out that Shirogane once dumped her. And although she manages to get Shirogane out, a rebellious spirit against Kaguya has begun to grow...
