The apocalypse erupts in a massive crisis. Humanity faces an existential threat from zombies, mutated plants and animals, snowstorms, and other natural disasters.
The female lead is reborn. After suffering through too many betrayals in her past life, all she wants this time is to find a place where she can build a home of her own, protect her younger sister, and survive in safety through the apocalypse.
The second female lead transmigrates. A soul from a parallel world transmigrates into the female lead's younger sister. She thought she'd been transmigrated into an apocalypse novel, and that all she had to do was cling to her big sister, the female lead, to reach the peak of life. But she never expected the female lead to be reborn. The female lead has given up on striving and just wants to quietly live as a lazy couch potato in the apocalypse. The second female lead thinks life is so hard.
