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...
I always thought I was bothering 
you by making a mess.
.لطالما ظننت أنّني أزعجك بصنع جلبة
Ich dachte, dass es dich
nerven würde, mir hinterherzufegen.
Siempre pensé
que te molestaba con mi desorden.
Siempre pensé
que te molestaba con mi desorden.
Je pensais que tu détestais
nettoyer derrière moi.
Ho sempre pensato di darti fastidio 
con il casino che facevo.
Sempre achei que a sujeira
te incomodava.
Я всегда считал, что только
досаждаю тебе беспорядком.
