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!
This is heaven!
!هذا نعيم
El paraíso.
El paraíso.
Sembra di essere in Paradiso!
Isso é o paraíso!
Райское блаженство!
