The letter from the future details the regret felt by everyone for being unable to celebrate Kakeru's birthday. As such, high school Naho and the gang pester Kakeru about what he wants until the big day. On the other hand, 26 year-old Naho and the gang gather at the late Kakeru's grandmother's house to celebrate his birthday, like they had promised in the past.
If things are rough, say so!
!إن كانت الأمور صعبةً عليك فقل ذلك
Wenn es dir wehtut,
dann sag das auch.
Si estás triste, dínoslo.
Si estás triste, dínoslo.
Si tu souffres, dis-le-nous !
Se stai male, dillo!
Se você está sofrendo,
 nos conte que está sofrendo!
Если тебе тяжело, говори!
