The Academy's Terminally Ill Side Character Novel

Everyone has friends in their lives, right? They can be anyone—good friends, bad friends, or even... friends with benefits. Ahem! Anyway, the point is, everyone has friends. And so did I. I was friends with author of web novel. Yeah, was. A small argument over how the main character should act in novel of [World’s Greatest Hero] led to a fight with my friend, the author. Still frustrated, I stormed out of his house... and that’s when Truck-kun hit me. But that wasn’t the worst part. The worst part? I woke up in a different body—the body of a side character in my friend’s novel. A character who is supposed to die in the prologue. [Your body is dying!] [You don’t have much time left.] [The creator of this world is mocking you.] F#ck you, Author. F#ck this novel. I will survive, and when I do—I'll beat you to a pulp!
