What I think...
To me, I can picture at the start, the "Puppet Master," laughing at how he somehow managed to ruin a strong friendship between some of the heroes of the story. The whole piece afterward is those mentioned friends living in their regrets and their resentments.
To say it simply, great job. You claim you're not much of a pianist, but I think you have lots of talent and potential. Keep up the good work. Your song here is more than inspiring.
