I Became a Dead Character in a Prison for Wastes

I opened my eyes… and I was the boss of a prison cell?! I've been transported into a novel… but, excuse me. What am I supposed to do when I've been sent here 10 years before the original story even starts?
The setting is a prison. The problem is, this place is worse than the jungle!
After struggling and surviving for 10 years, I became…
the boss of the prison.
"Hey, Mint. Knock it off. Seriously."
"I have no idea what you're talking about, sir."
