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.
Kakeru, as soon as school is over, 
come home right away.
.عد إلى المنزل فورًا بعد أن تنتهي المدرسة يا كاكيرو
Kakeru, komm bitte nach der
Schule sofort wieder zurück, ja?
Rentre tout de suite 
après l’école, Kakeru.
Kakeru, una volta finito a scuola
torna subito a casa, va bene?
Kakeru, volte assim que a 
sua aula terminar hoje, tá?
Какэру, когда закончатся уроки,
сразу иди домой.
