Yao An, a pleaser, sends every penny home. She wanted to sign up for a training class worth 3,000 yuan, but her mother scolded her. That night she stood in front of the mirror, said something to herself, and then died. The one who survived was Bai—cold as a knife, merciless, and pushed away everyone who Yao An did not dare to push away. But when Bai couldn't hold on anymore, the fire came, and when the fire was tired, the mirror came. The last person standing on the ruins was the six-year-old child who had never been seen before. They are all her. One person has to split into five people to survive.
