A century-old house, a curse passed down from generation to generation. An ancestral admonition is engraved on the wall: "If you hear the sound of the stairs late at night, never look back."
There is a "thing" living in the old house - a woman wearing embroidered shoes. A hundred years ago, she rescued her ancestors who drowned in the river on one condition: she would live here and sleep here. She protected the family from disasters, but the family could not look back at her. Whoever looks back at her will "switch" with her - she will go for that person, and that person will sleep for her, and they will never wake up.
