Sarah was reborn just before the arrival of the extreme winter apocalypse. In her previous life, she had been brutally murdered by malicious neighbors, and her remaining family members along with her beloved dog had unfortunately perished. She decisively sold their city home, convinced her aunt by leveraging unusual animal behavior to convert a mountain cave into a shelter, and depleted all their savings to stockpile food, heating supplies, and power generation equipment. When the June cold snap arrived as predicted, Sarah, along with her sister, aunt, cousin, and golden retriever, survived safely within the shelter. A year later, as the ice and snow melted, the disaster came to an end; the family participated in post-disaster reconstruction and embarked on a new life.
