I just finished this movie, I put it aside for a short while, and I regret it !

The story / plot was really beautiful, it shows that being in a stressful, and overworking workplace can really lead you to want to end it all. It perfectly showed the struggles of working in such place. The wanting to put down others because you don't want to lose your place, which can result in you breaking down because you may think that you failed immensely.
They even showed the "depression room" meaning he let everything go, he completely stopped caring, he let things rot until it as infested of bugs; the trash bags all over, and barely being able to see some of the floor. Even that one time where they showed that he suffered from insomnia (I believe he did, I'm not sure!) which is a serious thing that no one wants. And at the end, the plot twist was shocking nonetheless ! I really did not expect it.

As for the acting/cast; I was really impressed ! Asuka (Takashi) was really able to show the despair in his face when he was on the edge, I felt it through the screen. As for Sota (Yamamoto) his smile is contagious, and the fact that he seemed to be such a happy guy during the whole movie, up until we saw him in that bus, you noticed how broken he looked and I found that really amazing.

I personally didn't pay attention to the music so I won't comment on that.

Lastly, the rewatch value. I put a lower score because I cried so much while watching this film that I do not want to cry like that again, I will probably rewatch it someday but as for now, I'm still recovering HAHA!
