The untold stories of the unnoticed

Have you ever heard of those side characters? The people who have no significant role in the lives of people who actually matter. They're always there at the exact moment something important or tragic happens but they never seem too important in that story right? Now usually a side character goes unnoticed for the rest of the timeline, well let's change that. Let's see what a side character, like you and me, witness.

hello, my name is Kiomi, as in KEY-O-ME, and I'm a side character, an unnoticed person, a figure in the background of the important lives. I've witnessed more stories than you can possibly imagine and the shit that goes on in teenager's lives, it's some dumbass shit. Anyways, as I get news that I have acquired a small touch of cancer, I wonder, will I become the center of the story or remain the role I've been forced to play?
