At first, I was a bit annoyed by the male lead (played by Yamazaki), but then I remembered the context of the story. Sometimes the individual is frustrated with his/her career, is naive, doesn't have too much experience in life, so it's natural for him/her to screw up. It's hard to understand someone when yourself have troubles that you need to work on.
Both Yamazaki and specially Matsuoka done a terrific job in this film. Everyone is not perfect all the time and this film makes it clear. When you're used to watching "more of the same" or movies with certain tropes, you get unaccustomed at first with characters acting like real people, and this film captures that essence with success. Some scenes end abruptly, they lack music, but such is life. The real emotions this film invokes is making the audience put the pieces together in most of those situations. When I finished this film, all I could think about was how everything fit together by the end and I forgot I was watching a film altogether.
I hope this film gets better recognition and more people on Prime give it the attention it deserves.
