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. He stole her last supplies to please another woman and left her to die in a sea of the undead. But death wasn’t the end. She woke up days before the world collapsed. After cutting ties with her ungrateful ex and his parasitic family, a mysterious voice awakens in her mind, LUS, a Level-Up System designed to help her survive the coming end. With knowledge of the future and a system guiding her every move, she begins to prepare. She stockpiles resources, builds a base, and learns how to fight back against the horrors that once destroyed her. And when the apocalypse arrives again… she’s ready. But survival isn’t the only thing waiting for her in this new life. A silent killer who watches her like prey. A manipulative genius who wants to unravel her secrets. A gentle protector who sees the girl she hides. And a dangerous man who thrives in chaos. As the world burns and power shifts, they’re all drawn to her, each with their own motives, each with their own darkness. Even her past refuses to stay buried. Because now, the man who once abandoned her is back, broken, desperate, and begging for a second chance. Too bad she has no time for regrets. Not when she’s busy rising to power… and building a kingdom in the ruins of the world.

"I'll leave the decision-making to our children. Girls, do you want 100 million dollars, or your mother?" On the day our parents get divorced, Mom looks at us with tears in her eyes. My older sister, Camila Walker, kneels before Mom while looking very emotional. "I want to stick with you, Mom! I don't want money—I just want you!" As she looks at me, she smiles confidently, as though she's won something. In my previous life, Camila didn't hesitate to choose Dad, who had inherited 100 million dollars. But he lost all of his fortune to gambling to the point that he had to sell Camila just to pay off his debts. Left without a choice, she was forced to take her own life. As for me, I chose to be with Mom, only to find out that the "poor security guard" she had married turned out to be the richest CEO in the city. Thanks to the marriage, I became the spoiled and pampered heiress whom the entire city envied. Camila thinks she's stolen my good luck. Little does she know that I died in my previous life as well.

A thirty-year-old office lady, who got into an accident and is now trapped inside a novel series she loves. She was reincarnated into one of the side character extras of the story and meets in person the tyrant magician, the playboy prince, and the clueless female lead of the story.

My younger sister, Chloe, and I were transmigrated together into a beastworld continent. Beastmen are classified into four distinct ranks: S, A, B, and C. The tribe chieftain, Gideon, gathered all the single beastmen in the tribe for us to choose from. Chloe chose Garrett, the only A-rank werewolf in the entire tribe. She gave birth to five consecutive litters, yet all her children turned out to be mere B-rank beastmen. Furious, Garrett dissolved their mating bond. The other males refused to take her in either, entirely because the offspring she produced were of a mediocre grade. Meanwhile, I chose a B-rank snake shifter and gave birth to ten children in a single litter—all of whom were A-rank. The entire tribe revered me as a divine lady, and the snake shifter successfully inherited Gideon's position. Consumed by sheer jealousy, Chloe poisoned my ten children to death and pushed me off a cliff, leaving me to plunge to my death. Yet, when I opened my eyes again, we had returned to the exact day of selecting our mates. Without a single moment of hesitation, Chloe chose the snake shifter. I knew right then that she had been reincarnated too. But this time, the children she gave birth to would not even qualify as C-rank.

Five minutes before the graduate admission exam began, the campus heartthrob quietly slipped a crumpled piece of paper into my pencil case. Lines of floating text drifted across my vision. [The paper is filled with answers. The school heartthrob has reported it, and the proctor will be here any second!] [As long as they find it, his admission slot will be canceled immediately!] [Serves this bookworm right for standing in our heartthrob’s way. The proctor is his aunt. He’s doomed today!] The next second, the proctor stormed into the classroom and headed straight for my seat. “Someone has reported you for cheating,” she said sharply. “Empty your pencil case. We’re checking it.” Without a word, I turned the case upside down. A few pens fell onto the desk, but there was no paper. The campus heartthrob’s eyes widened in disbelief. “How is that possible? I–” Before he could finish, a slip of paper covered in answers slid out of his own pocket and dropped onto the floor. What they didn’t know was that I was born with a weird power called “Misfortune Rebound.” Anyone who tried to harm me would end up suffering the consequences themselves.
