Ever wonder what it's like to argue so hard with a friend that you end up paying the ultimate price? Our protagonist is about to find out, in the most bizarre way imaginable. He was just a regular guy, hanging out with his novelist buddy, when a heated debate over the direction of the web novel *World's Greatest Hero* turned sour. A slammed door, a fateful encounter with Truck-kun, and BAM! He's not just isekai'd; he's been reincarnated as a minor character within the very story they were fighting about. But here's the kicker: he's not just *any* side character. He's the terminally ill one, destined to kick the bucket in the prologue. Talk about a bad hand. Now, trapped in a weakening body and facing a ticking clock, he's got a serious bone to pick with the author—his former friend. Armed with future knowledge and a burning desire for revenge (and survival), he's determined to rewrite his fate and give the creator of this world a taste of his own medicine. *The Academy's Terminally Ill Side Character* promises a wild ride of defiance, dark humor, and unexpected twists. It's a story about friendship gone sideways, second chances, and the sheer audacity of refusing to die when a writer—or fate itself—says you should. Will he defy his predetermined end, or will the author's pen prove mightier than his will to live? Dive in to find out!
