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...
is causing something inside his head 
to expand and turn into popcorn.
.يسبّبان في توسّع شيء داخل رأسه وتحويله إلى فشار
dehnt sich irgendwas in ihm aus

hace que algo en su cabeza
estalle como palomitas.
hace que algo en su cabeza
estalle como palomitas.
quelque chose finit par éclater.
fa espandere qualcosa nella sua testa 
e lo trasforma in pop-corn.
está fazendo algo em sua cabeça
se expandir em forma de pipoca.
в его голове что-то лопается и
превращается в попкорн.
