Kuro's classmate Aona is troubled by the popcorn that keeps popping out of his head. Aona says it makes him sad when the popcorn disappears, so Ramune lends him a bag that can be used to store the popcorn. Why is Aona's head producing popcorn, and why does he feel sad when it disappears? Ramune tells Aona that the treatment method will become clear if he asks himself those questions...
Apparently she's been stressed

Al parecer, ha estado angustiada
porque no ha podido decírtelo.

Elle n’osait pas te le dire,

Parece que ela não conseguia falar isso
e estava sobrecarregada.
Она держала всё в себе, так как
не могла тебе об этом сказать.
