"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?

An Extra's POV: My Three Fiancees Hate Me

Riven and Quin watched as he slowly transformed. Pop, pop, his bones shifted, his body grew in size in a way that looked extremely painful.

Suddenly, Quin dashed toward the boy. He stretched out his hand—a black sword materialized. The best way for him to take down the boy was now, before his transformation was complete.

He stabbed right for the boy's head, but the sword hit a barrier. The barrier absorbed all the force, and a massive explosion of force followed, throwing Quin back.

Quin flipped in the air and landed on his feet. He skidded back a few meters before he finally stopped.

"Hahaha, hahaha. Did you really think I wouldn't prepare for you, Sir Quin?" the boy roared, his voice contorting as he spoke. His change became faster, his skin changed color, and soon he became an eight-foot-tall humanoid creature.
