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!

no fui el primero en el baño.
Je n’étais pas le premier.
Non sono il primo ad aver fatto il bagno.
Eu não fui o primeiro no banho.
Я не первый...
