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.
It's not about what Kakeru will think of me.
.إنّه ليس ماذا يظنّ كاكيرو فيّ
Es geht nicht darum,
was Kakeru über mich denkt.
No importa lo que piense Kakeru.
No importa lo que piense Kakeru.
Peu importe 
ce que Kakeru pensera de moi.
Non mi interessa cosa
 possa pensare Kakeru di me.
A questão não é o que o 
Kakeru vai pensar de mim...
Какая разница, что
подумает обо мне Какэру.
