I have become the strongest extra

Asher is a man who, if he doesn't die from illness, will die from exhaustion because of his work in a fraudulent company. He dies in a car accident and is reincarnated in a novel he was reading, not in any character, but in the body of the top student at the academy who dies at the beginning of the novel. "Hahahahahaha" Damn you author but I'm not going to die without doing anything
