Iori continues to contend with the constant nudity of his male peers, but everyone dresses for dinner, which is when Nanaka observes he’s gone out every day he’s been in Izu, and doesn’t even know where his room is!
Nanaka forcefully forbids him from spending a third night out, but when the boys say they’ll be having drinks with students at a women’s university, Iori begs Nanaka to let him go. She refuses.
Iori doesn’t give up there, an decides he’ll unpack his stuff and set his room up in a way that will convince Nanaka to change her mind. Kotobuki and Tokita volunteer to help, and eventually Imamura is also involved in various ill-conceived makeovers.
They festoon his room in porn, then lolis, then BL, and finally, in order to sway Nanaka most powerfully, slap Chisa’s face on everything. In the last case, Chisa ends up seeing their handiwork before her sister.
It’s a competent example of the “best laid plans” comedy trope, in which Iori keeps trusting his friends, things just keep getting worse, and he just grows more angry and frustrated. His own idea is worse still, suggesting the entire venture was doomed from the start!
Chisa banishes him to an isolated room that also happens to be the meeting room for the diving club; Iori only learns this when he wakes up to find a meeting taking place in the room, and the club ain’t vacating!
Kotobuki and Tokita decide to give the three freshmen—Iori, Imamura, and Chisa—some basic lessons. Chisa is forced to participate despite already being well-versed in said basics.
The swimming lesson goes south when Iori is treated to the sight of way more underwater manhood than with he’s comfortable. The senpais even trick him into totally disrobing just when Chisa emerges from the changing room in her orange bikini.
Iori just can’t seem to prevent Chisa from seeing him in almost exclusively embarrassing and shameful situations!
But when Iori idly says he’s not interested in underwater—something she’s painfully passionate about—Chisa has Nanaka take Iori to the aquarium after-hours.
This visit and the majesty of the underwater to which divers have access doubtlessly inspires Iori, but so does video he sees of an entirely different side of Chisa; one he never sees because he always looks like a jackass around her.
Nanaka is honest about Chisa telling her to take him and why, and the next time Iori sees Chisa, he makes sure to express his gratitude, both by being fully clothed, and by giving her a souvenir. Chisa would’ve preferred a cuter trinket, but she clearly appreciates the gesture.
This was by far the least cringe-worthy interactions between the two childhood friends, and hopefully the start of a trend of more cordial encounters. Still, I also hope the show doesn’t stop mining Iori’s embarrassment/jackassery around Chisa for comedy…it’s still a rich mine!
