You know this film deals with the consequences of a very hard reality and unfortunately something that is becoming more common in Japan, namely suicide . What makes it so unusual is the acting from the very young cast whose eyes you see the story unfold through.  I was astounded by the acting from the young lead actress, amazing performance for someone so young as she was able to confer some really difficult emotions which even adult actors would find difficult.  Really well done on this film for dealing with such a difficult issue in such a thoughtful way.
