An Extra's POV: My Three Fiancees Hate Me Novel

Luke, an obsessed light novel reader, posts a critical review of "The Hero's Obsessed Harem," condemning its protagonist for stealing other men's love interests. The author responds with a cryptic threat, and Luke mysteriously awakens in the body of Riven Von Grave, a minor character from that very novel. Riven is the fourth son of a low-ranking baron family, engaged since childhood to three duke's daughters who abandoned him for the story's hero. According to the plot, he is destined to die forgotten in an upcoming war against demons. Determined to escape this fate, Riven—now driven by Luke's consciousness, a mysterious system, and pure spite—sets out to rewrite his destiny and reclaim his fiancées. However, as he manipulates the story's events, he inadvertently triggers a catastrophe far worse than the demon war itself. Faced with the consequences of his own interference, Riven must confront whether he can undo the damage he has caused.
