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...
But judging by earlier, he doesn't 
have any friends at school.
.لكن باعتبار ما حدث سابقًا، لا يملك أيّ أصدقاء في المدرسة
Aber vorhin machte es den Anschein,
als wenn er in der Schule keine Freunde hätte.
Pero, a juzgar por lo de antes,
no tiene amigos en la escuela.
Pero, a juzgar por lo de antes,
no tiene amigos en el instituto.

non ha amici a scuola.
Mas, pelo que vi aquela hora,
ele não parece ter amigos na escola.
Но, судя по всему,
в школе у него совсем нет друзей.
