"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

Back at the second-year section, Treshan and Louis walked toward a training room. Without knocking, they pushed the massive door open.

The first sound they heard was a massive explosion, and at the center of it was a boy in black combat clothes. His neck-length white hair fluttered from the blast.

In his hand was a training scythe. His eyes were sharp, and there was a crazy smile on his face.

"Is that the best you can do, Amelia?" he yelled at the girl standing on the opposite side. She had fiery red hair and eyes, and in her hand was a staff with a large red crystal on it.

"Don't forget about me!" another girl ran from behind. She leaped into the air and swung her sword, putting all her strength into the strike.

The white-haired boy moved to block the attack, but the sword suddenly vanished. His danger signal went off, and he immediately retreated as fast as he could.
