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...
Then try to spot the differences between 
today and days when you do produce popcorn.
إذًا حاول أن تجد الاختلاف بين اليوم 
.والأيّام الّتي كنت تنتج فيها الفشار
Dann denk mal drüber nach, was heute
anders lief als an jenen Tagen,
Piensa en qué se diferencia hoy
de los días en los que haces palomitas.
Piensa en qué se diferencia hoy
de los días en los que haces palomitas.
Alors essaie de comparer cette journée
à un jour où le popcorn sort souvent.
Allora prova a trovare le differenze fra oggi 
e i giorni in cui produci pop-corn.
Então tente achar a diferença entre hoje
e os dias em que sai pipoca.
Тогда постарайся найти различия
между сегодняшним днём и теми днями,
