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...
And when I had that thought, popcorn 
started coming out of my head.
.وعندما ساورتني تلك الفكرة، بدأ الفشار يخرج من رأسي
J’y pensais justement
quand du popcorn est sorti de ma tête !
E proprio quando l'ho pensato, 
hanno iniziato a uscirmi pop-corn dalla testa.
Quando pensei nisso, começou
a sair pipoca da minha cabeça.
Стоило так подумать, как из головы
начал выпрыгивать попкорн.
