Preservation: A short story by a friend

Hi guys, long time no see. In the middle of my GCSEs right now, but my friend recently sent me a piece of writing, and I think it's pretty good. Therefore, I've chosen to share it with you. His name is Chemical and he's very creative. With regards to the ending of the story, there is no cause for concern; he is not suicidal, I have been assured.
This is a short story about . . . well, I'll leave you to decide that.

Simple, unassuming, and above all, intriguing: this is Preservation.
