The first semester has come to a close, and the Ikeda lab is having a party where everyone's bringing what they like to eat and drink. They're having fun, playing games like the "prime number Yamanote line game," when a drunken Himruo finally does a certain something with Yukimura... And even Kanade ends up drunk... On the other hand, the mood quantifier obtained through the previous round-robin kiss experiment has progressed their research tremendously, and in order to gather more data, Yukimura and the others use fairy tales such as "Snow White," "Kaguya-hime," and "The Crane Returns a Favor" as references, but...
Oh, right. Kanade, you weren't at the 
party we had in April, were you?
صحيح يا كانادي، لم تكوني في الحفلة التي أقمناها
 شهر أبريل الماضي، أليس كذلك؟
Ach, Kanade, du warst ja gar nicht
auf unserer Feier im April, oder?
À propos,
on t’a pas vue au pot d’avril.
Oh, giusto. Kanade, tu non c'eri alla festa
che abbiamo fatto ad aprile, vero?
Ah, é. Você não estava no Happy Hour
anterior, não é, Kanade?
Кстати, Канадэ, тебя ведь не было 
с нами на апрельской вечеринке?
