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.
