I was able to avoid having to read this in high school but I did know it by reputation and really wasn't interested in it.  But being the completionist that I am I wanted to bring my Yamapi watched list to current.  I am now sorry I waited as long as I did to see it because Yamashita Tomohisa totally owned the main part in this.  His mannerisms in the beginning are spot on, we have a friend of the family who is autistic and I recognized the signs. As the story and the character changed so did the acting and you believed it.

Yamapi has been criticized in the past for his "wooden acting" but this work just blew it out of the water.
