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!
Did I fall asleep again?
هل نمتُ مجدداً؟
Bin ich wieder eingeschlafen?
¿Me dormí de nuevo?
¿Me dormí de nuevo?
Hein ? Je me suis encore assoupi ?
Oh? Mi sono addormentato di nuovo?
Dormi de novo?
А? Я снова заснул?
