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.
The future me and the future Suwa are probably
نفسي المستقبليّة وسوا المستقبلي ربّما
Wahrscheinlich sagen Suwa
Creo que tanto mi yo del futuro
como el de Suwa
Creo que tanto mi yo del futuro
como el de Suwa
Il semblerait 
que la Naho et le Suwa du futur
Probabilmente la me stessa
 e il Suwa del futuro
Tanto a minha versão do futuro
 quanto a versão do Suwa
Должно быть, будущая я и будущий Сува
