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.
Stop feeling regret.
.توقّف عن الشعور بالندم
Hör endlich auf,
irgendwas zu bereuen.
No te arrepientas más.
No te arrepientas más.
Arrête d’avoir des remords.
Smettila di biasimarti.
Pare de ficar se culpando.
Хватит уже жалеть.
