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 already dumped you. 
You're the one who should give up.
.لقد ترككِ كاكيرو بالفعل. أنتِ من عليه أن يستسلم
Wer wurde denn hier verlassen?
Gib also besser du auf.
A ti te rechazó, así que ríndete tú.
A ti te rechazó, así que ríndete tú.
Kakeru t’a larguée, c’est toi 
qui ferais mieux de l’oublier.
Kakeru ti ha già scaricata,
dovresti essere tu ad arrenderti.
Já faz um tempão 
que você levou um fora.
Какэру тебя уже бросил,
сама забудь о нём!
