When the world ended, it didn’t happen all at once. First came the storms—endless, violent, wrong. Then the dead began to rise. Now the outside is a death sentence, and the tenants of a single apartment building have made one rule: stay inside, no matter what. Y/n has no family, no one coming back for her—just a guarded door, a growing list of rationed supplies, and a pregnant German shepherd that refuses to leave her side. Then the ring she’s worn her entire life burns. [Survival System Activated.] Tasks. Points. Rewards. A chance to live—if she’s willing to risk stepping outside. The system doesn’t make her safe. It makes her stronger. Slowly. Carefully. One choice at a time. Vines that move. Roots that bind. Power that grows with every task she survives. But the storms are getting worse. The dead are changing. And whatever chose her… is still watching. Inside the building, people are holding on. Outside, the world is falling apart. And Y/n is caught in between—trying to survive long enough to figure out why she was chosen at all. Because in a world like this— survival isn’t given. It’s earned.
