- Description from novelbuddy

I fell into a game world out of nowhere with an instant kill skill.
And then somehow, I became a bigshot.

In the midst of a ruined forest, due to the result of the clash between peak powerhouses, a body of a man lay. He was known as the 'Evilest Villain', the worst man ever born in humanity.His body was full of wounds with a spear piercing his heart. However, even in his final moments, he was calm and collected, with his usual cold face.

The only thing on his mind was, “Forgive me, I couldn't keep my promise to you.”

He closed his eyes, ready to begin his eternal slumber in the darkness.

Suddenly, a blue light appeared, with ancient text that read, 'Do you want to turn back time, my child?'

He laughed and said yes.

The Devil’s Den was Cosette’s favorite webnovel that she had followed for three whole years. She waited for updates, wallow in those empty days during the author’s constant hiatuses, cry and laugh with the characters; it was already a part of her short life.

Cosette really wished that the novel would never end despite that she was terminally ill.

But after three years, The Devil’s Den finally came to an end. With a reader as invested as Cosette, she had mixed emotions about the ending. Not that the ending was disappointing, but what disheartened her was the ending of her favorite character; the villain Maxen Devilsin.

One year later, Cosette took her last breath only to wake up in the body of the stunning Cosette Blac; the villainess of the novel The Devil’s Den, her second favorite character after the villain.

Granted with the opportunity to live in the world of her favorite novel before the main story starts, Cosette had a plan.

That was to simp over the characters and save her favorite characters whilst hoping that the female and male lead still have their happy ending.

In a world that was already written and events that were expected to happen whether or not they wanted to, can Cosette change the course of their lives? Was overwriting the characters' fate could save them? Or would it just give them a much worse ending than what the author had given them?

Watch Cosette as she tried to become the superfan and give the dark-themed story some light.
