The Side Character's Betrayal

Every story has a supporting character. They might make you feel sorry for them, or they might make you resent them. What will happen when an unknown bit-part actor unexpectedly takes their place?

P.S. Each story will probably be posted once it's more or less finished. The author updates at their own pace, so feel free to read at your own pace too. Share any thoughts in the comments, though the author probably won't read them. Even if they do, there's a good chance they won't be able to make changes, because the author is very lazy.

This novel and its characters are entirely fictional. Any resemblance to actual people or events is purely coincidental. Do not imitate.
