This movie is truly a beautiful message about life itself. As we follow the life of a young adult remembering his life as an high-school student, we explore the life of his closest friend, a guy named Sasaki who really is unique. In first sight, it look like a normal life for theses kids but we discover how sad Sasaki really is and how the main character is crushing his own dreams. For the whole movie, you'll be surprised by the beauty of almost every sequence. In the very end, the message that this film tried to give us is evident :

Live life as it goes. You don't need to always say goodbye to things or you'll end up regretting it. Finally, I'll quote the movie itself.

" Don't try to fool me ! You're always saying goodbye !

Because that's what life is, A long, long goodbye ! And one day, the final goodbye will come !

It'll be a goodbye to yourself ! "
