As punishment(?) for neglecting her at the festival, Chisa puts the word out that she’s dating Iori, immediately making all the other guys at college hate him and wish him ill will in a very over-the-top, repetitive opening act that went on a bit too long.
Chisa does nothing to stop the false rumor—on the contrary, she fans the flames—and Iori tells the guys that Kohei is dating Azusa (making him Public Enemy #2), but they both get a reprieve when they promise to arrange a mixer for them.
Oddly, their job is made easier by the fact the legions of haters are curiously whittled down to just two ornery classmates. To that end, they beg Azusa to introduce them to other women at her college. She agrees, but only if Iori continues to act like Chisa’s boyfriend until, as she puts it, Chisa “accepts it.”
With Iori’s promise secured, Azusa introduces her kohai, none other than Yoshiwara Aina, who the lads find extraordinarily adorable when she’s not wearing the thick layers of makeup that earned her the unwanted nickname “Cakey.”
Aina has wanted to join the diving club anyway since the festival, leaving the tennis club full of fakes who treated her like shit. Despite calling her cakey and drooling over her non-cakey appearance, Aina is still willing to scrounge up three of her friends for the mixer. But she also gives Chisa one hell of a sidelong glance; I believe Chii-chan just got some competition.
The quartet of lads, among them a virgin who will sleep with any girl as long as they’re a girl and he can sleep with her, are shocked to find Aina has somewhat tainted the mixer by giving her three friends as well as herself the same Cakey treatment, giving them the appearance of four clowns.
But if the girls are clowns, the guys are circus animals, constantly jockeying for attention and braying and snorting at one another whenever more than one of them focuses on one girl. Like the lecture hall scene, it gets a bit repetitive.
A look at a selfie shows them one of the girls is quite attractive behind the makeup, and they all go after her, but when Kohei asks her if she’ll come to his place later all four girls retreat to the restroom.
Iori uses the time to inspire his men, only to steal the show, thus invoking the other lads’ collective ire. Kohei breaks a mixer taboo by blurting out that Iori has a girlfriend (something he can’t deny lest he break his promise to Azusa), but the girls don’t even care; they already know that fact.
Later, the girls laugh off the mixer as an entertaining lark, likening it to going to the zoo. But Aina, ever the romantic, still ponders whether the person who saw through her cakey makeup and helped her out when she was down in the dumps could be a good match for her. No doubt she sees a decent guy beneath Iori’s own thick layers of alcohol-soaked machismo.
