Kim Sangmin's definition of villainy is simple: it's the role that ends the story. But when he finishes reading a novel, only to wake as its defeated villain, his carefully ordered world shatters. He refuses the fate written for him. With a younger brother depending on his survival, he can't simply accept death and abandonment. Instead, he'll defy the narrative itself by becoming the hero—the true, irreplaceable protagonist. His strategy is bold: stalk the story's actual main character, intercept every crucial moment, and claim the spotlight that was never meant to be his. He'll dismantle the original hero's destiny piece by piece, rewriting his own role through calculated intervention and relentless positioning. It sounds impossible. It should be impossible. But Kim Sangmin has already cheated death once by waking in this world. With his brother's future depending on his actions and his status as a role model on the line, he'll stop at nothing to prove that even a destined villain can rise as a hero.
