From the first chapter and the premise I had high hopes, but it somehow under-delivered. Setting aside that it seems to have been cut short for some reason, overall I would say it's just a little weak in many parts. I can't quite formulate what is it that is lacking, but doesn't hit like it could. Nevertheless, it was a nice read
For similar theme, but executed in a different, in my opinion better, way, I recommend ReLIFE.
