Once again Miyuki is relied upon by a fellow student for romantic advice, only this time, it’s something he’s confident he can handle: how to hold a girl’s hand. I mean, he has shared an umbrella with one already, no?” Miyuki makes this all about economics, urging the boy to get a job so he can afford surgery for his sweaty hands, training for a boater’s license (which Miyuki himself inexplicably has), and rent a boat on which to introduce his hand to Kashiwagi’s.
Her “Love sense” going off, Detective Chika intervenes and offers the much simpler and much more affordable advice of “do your best,” which the lad takes with gratitude and ends up succeeding, sweaty palms and all. The eavesdropping Kaguya, not wanting Miyuki’s work to spoil her summer plans for him, offers side-splitting commentary during the advice session, while Miyuki loses the round because thanks to Chika he lost a potential part-time recruit.
From there we transition to a budget session between Miyuki and Yuu, with the latter going off on various anti-youth rants fueled by his jealousy for the sports club members getting all the girls. The two main status pyramids at the academy are that of economic background (how rich your parents are) and clubs (with anime club being below “no club at all” in precedence).
Miyuki is just trying to keep Yuu focused on crunching the numbers, but also says that participating in a cultural club is possible in the StuCo, as Chika (board games) and Kaguya (Japansese archery) are both club participants. That sends Yuu on a different rant, as he describes Kaguya’s flat chest as perfect for archery, compared to the bouncing Chika would have to contend with.
Little does he know both girls are right behind him. Chika carefully crafts a paper fan with which to beat Yuu senseless. When Yuu heads home to prepare a will, the girls start pulling at Miyuki, urging him to join their respective clubs. Even though he ultimately has to turn both down (his part-time job precludes clubs), he lets them tug at his arms for a bit, because it’s nice to be popular. This nets him a win to cancel out the first segment’s loss.
The third act doesn’t declare a decision either way for Miyuki or Kaguya, but the latter ends up embroiled in a fit of uncontrollable, boisterous laughter every time Chika says “wiener” in relation to her dog. While Miyuki has made great strides in her social interaction, she’s still a grade schooler when it comes to dirty words (or those that can be construed as such).
Once Chika realizes every time she says “wiener” Kaguya can’t help but roar with laughter, she’s already won; after all, she loves hearing Kaguya laugh, and the louder the better. She takes it up a notch when Miyuki arrives, threatening to make him say the word “wiener”, causing Kaguya to debase herself in front of her beloved President.
When Chika fails every time due to verbal blocks from Kaguya, she gives up and loudly protests that Miyuki “won’t give her wiener.” The resulting torrent of double entendres mortifies Miyuki, who quickly flees, while Yuu listens in on Chika’s continued liberal use of the word “wiener” from the other side of the door, his nose bleeding profusely. Winner: Chika.
