- Description from Novelupdates

One day when she was thirteen years old, while chewing bread as a snack, Dalia Pesteros suddenly remembered her past life. This is an impoverished otome game world where the main characters go crazy, and she was born as the sister of the worst villain in the future!

There is no solution at this rate. The family will be exterminated, and I will be thrown away. So, no matter what, I must get out of this family as soon as possible!

‘Now that it’s like this, I need to lower their guard and run away.’

In order to get rid of the relatives who aim for the family and the sly emperor, it’s better to be in good favor with my brother-

“I want to dance with Dalia. What’s the problem?”

“I’m sorry, but my sister is shy.”

“Dalia said I was her favorite!”

Somehow, it’s not only my brother that I tamed, but all the strongest characters in this world are obsessed with me!

“You are offering me a marriage of convenience, but princess… there's nothing convenient about me.”

Izabelle had underestimated the fire she thought she was going to play with tonight. But how could she ever have foreseen that the man she had happened to come across with does not play with just a small fire, but a whole inferno?

Excerpt:

“You going through this marriage with me might as well be like you digging your own grave. Because the moment you start to want more from me, I will divorce you. And the moment you break your promise and try to fight me… I will ruin you and break you apart completely. Mercilessly. You will regret ever meeting this devil tonight.” His threat was given in the same soft but cold voice.

But Elle did not even flinch. Her gaze never faltered either. This man was ruthless, and she knew that clearly. His eyes that moment promised nightmares and darkness without any promise of respite.

But no matter what he says now, it would still not change her decision. She truly had no other choice.

“I understand now…” she said quietly, steeling herself. “Since you don't trust that I will keep my word, how about we do this? You prepare the divorce documents beforehand now and I'll sign it. That way, once you decide to divorce me in the future, the papers would already have been signed and there would be no way I can trouble you about it. You would just need to send it to the lawyers and have it notarized.”

A heavy silence reigned before his quiet disbelieving laugh broke the silence.

“I'm at a loss for words, Princess Izabelle.” He looked wickedly amused. But then he started nodding in approval. “Fine, princess. I will marry you.”

No one knows when the first Clough door appeared. All people know is that a new era began when it was pushed open.Fortresses, sublimators, pillars of star essence, three-dimensional armaments, infinite energy, who can escape the sweeping tide of the times?In the abyss, the reverse realm, the skins, the alien gods, the mad king, the rulers, and the dark creatures, all howl in madness!Inside the black mist, the demons and ghosts crawl forward as a cross-dimensional migration silently brews.
