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!
It's a little hard to watch, really...
...من المؤلم مشاهدة هذا حقّاً
Irgendwie kann man
das nicht mit ansehen.
Es difícil ver esto.
Es difícil ver esto.
Je ne peux pas regarder ça…
Guardarli mette tristezza...
Na verdade, é um pouco difícil de ver...
Не очень-то приятное зрелище...
