Until Adrian woke up inside the story. He didn't reincarnate as a harmless bystander. He woke up as Prince Elian Ashford—the tyrannical prince destined to destroy Cassian. Worse, a cold, ruthless World System instantly locks onto his soul, forcing him to keep the original tragedy on its "correct" path.

In a world where Omegas are born to obey, submission is not a choice, it's an expectation. Klein has spent his entire life defying that expectation. Fierce, stubborn, and unbreakable, he refuses to bow his head to anyone. While other Omegas accept their fate, Klein fights against it. He doesn't beg. He doesn't cry. And he certainly doesn't kneel. No matter how cruel the world becomes, he refuses to let it break him or control him, not after everything he has survived. But fate has a twisted sense of humor. The Omega who feared nothing finds himself on his knees, desperate and pleading. Not for forgiveness. Not for mercy. But for the attention of the two men who have completely unraveled his world. The infamous twins of the Blackshadow Pack. Powerful. Ruthless. Untouchable. And for the first time in his life, Klein discovers that rebellion becomes far more complicated when the people you refuse to obey are the very ones you can't resist.

When the apocalypse came, she lost everything. Starving, hunted, and desperate, she trusted the one man she loved… only for him to betray her in the cruelest way possible.

I picked up a system with my sister. The system said only one of us could bind to it, and the other could take twenty million dollars. My sister shoved me aside and chose the money. Ten years later, she squandered everything and ended up homeless. Relying on the luck the system gave me, I excelled in my studies, climbed the career ladder, and reached the peak of my life. Driven by jealousy, my sister stabbed me to death at my birthday party. When I opened my eyes again, I was back to the day we found the system. This time, she said without hesitation, “Luck is too intangible. I’ll take the loss. You can have the fortune.” I knew she had been reborn, too. What she didn’t know was that the luck granted by the system always came at the cost of one’s lifespan.

I get reborn, this time bound to a simp system. In my previous life, when the apocalypse happened during Christmas Eve, I gave Victoria Blake, a beautiful woman, shelter and respite, only for her to backstab me in the end. Apparently, she had revealed my home's location to a scion named Tristan Cole when I wasn't paying attention. Not only did those bastards take over my shelter, but they also tossed me to the zombie horde. When Tristan asked Victoria if she felt guilty, she just reclined in his arms while tittering daintily. "That's just one of the lapdogs I've reared. If he's dead, then so be it." Now that I'm given a second chance at life, I'll make sure to repay them for the pain and hurt they've caused me in my previous life.
