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.
My mom nags me every day.
.أمي تزعجني كل يوم
Meine Mutter nervt
auch jeden Tag rum.
Mi madre cada día me da un sermón.
Mi madre me sermonea cada día.
Moi aussi, 
ma mère me casse les oreilles.
La mia è sempre pronta a lamentarsi.
A minha mãe também 
me irrita todos os dias.
Моя мама ворчит каждый день.
