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!
They're so ugly it's making 
my adorable eyes ache.
إنّهم قبيحون جداً لدرجة تجعل
عينيّ الجميلتين تتألّمان
Sie sind so grässlich, dass meine
Augen zu schimmeln anfangen!
Es tan feo que hace
que me duelan mis lindos ojos.
Es tan horrible que hace
que me duelan mis bonitos ojos.
Sono così brutti 
che gli occhietti carini di Maasa fanno male.
Isso é tão feio que faz meus
adoráveis olhos doerem.
От их уродства мои прекрасные
глазки слезятся.
