I was not expecting this. However, I am not disappointed by the ending at all, to be honest. (Ending as in chapter 5) It had opened my eyes to the fact that a story can end without explaining much about the feeling of one of the main characters towards the other. In this case feelings of Paul towards Andrew. Also without having the main characters end up together. A great short story, and great graphics.
