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!
But Kyotaro-kun's way of speaking 
hasn't changed much, I'll admit...
لكن طريقة كيوتارو-كن في الكلام
...لم تتغيّر كثيراً، سأعترف
Aber Kyotaro-kun, du hast dich von Mimik
und Gesprächsstil her kaum verändert.
Pero la forma de hablar
de Kyotaro-kun es igual.
Pero la forma de hablar
de Kyotaro-kun es la misma.
Mais toi, on dirait que
ça n’affecte pas ta façon de parler.
Anche se ammetto che dal punto di vista
di Kyotaro-kun non è cambiato molto...
Mas o modo que o Kyotaro-kun
fala não mudou muito, eu admito...
Но вынужден признать, что твоя манера
говорить и правда не изменилась...
