“Who would have thought that one ordinary review could instantly fuck your life? Definitely not me”******Luke was your average teenage boy—with an unhealthy obsession for light novels.After finishing a new read titled “The Hero’s Obsessed Harem,” he jumped online to post a review. His biggest issue? The so-called “hero” kept stealing other men’s love interests, and somehow, the story praised him for it.Right after posting the review, he got an odd reply from the author:“You think my book is flawed? I’ll make you regret that.”Luke brushed it off as a salty writer who couldn’t handle criticism—until everything went dark.The next time he opened his eyes, he was in the body of Riven Von Grave, the fourth son of the low-ranking Grave baron family—an irrelevant extra in The Hero’s Obsessed Harem. Riven was a forgotten character, engaged to three duke’s daughters since childhood, only for all three to abandon him for the so-called hero. And to make matters worse, he was fated to die in a war against demons—utterly forgotten.But Luke isn’t having any of it.Screw fate.Screw the plot.And most of all, screw the author who threw him into this mess.Armed with a mysterious system and pure spite, Riven is going to rewrite his destiny, and win back his fiancées as well.But with every change Riven makes, he changes the story, and pulls a calamity bigger than the demons toward them. What will he do when he realizes the impending doom, will he be able to fix his own mistakes?
