While taking their usual bath, the boys discuss how much Kyotaro is like an old man. The next day, when they go to school, they find themselves exhausted by climbing up the stairs... and learn that they're all becoming old men!
What, you aren't happy about it?
ماذا؟ لستم سُعداء بذلك؟
Hm, seid ihr nicht zufrieden damit?
¿Eh? ¿No les alegra?
¿Eh? ¿No os alegra?
Eh? Non ne siete felici?
Vocês não estão felizes com isso?
А вы что, не рады?
