I got transmigrated into a book, but—excuse me, what?! What am I supposed to do when I transmigrate ten years before the original story even starts? The setting: prison. The problem: it's worse than the jungle. A lawless war zone. After rolling through hell for ten years, I became... The leader of the prison. "Hey, Mint. You might wanna chill." "I'm afraid I don't know what you're talking about, sir." I ended up a swaggering prison gang leader. But hey, I'm fine with this. This is what we call the privilege of a long-time survivor. "On paper, you'll be considered dead. In return, you'll do a job for me." "I'm afraid I still don't understand, sir." Then a chance came—like a lie made real. "Help me, and I'll get you released." "What do you need, Master?" "..." The prison chief gave an order to me—now known as the prison's #1 certified nutcase: "Turn the new guy into the boss of this prison." They call it prison, but this place is a total free-for-all. And if I manage to crown one man as the next boss, I finally get out. "But the place you're going to... is the men's prison." "...Huh? I don't exactly have the thing for that?" "Disguise. Got it? Disguise!" ...Except—oops? Turns out that new recruit? He's the original male lead. (Source: Kakao Entertainment Corp., translated)
