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!
Like the flowers that 
bloom across the world...
...كما الزهور التي تتفتّح في أنحاء العالم
So, wie es Blumen auf der Welt gibt.
Como las flores en el mundo.
Como las flores en el mundo.
Que les fleurs
recouvrent cette terre.
Come i fiori che sbocciano in tutto il mondo...
Como as flores que desabrocham pelo mundo...
Словно распускающиеся цветы...
