When Lin Xia, a girl living alone, was moving, she accidentally discovered a stack of unopened old letters hidden deep in the closet of a rental house. The envelope only said "To the next guest" and the date of signing was three years ago. When she opened the first letter, she found that the content accurately predicted the details of her life after moving in. As the letters were opened one by one, she gradually realized that the previous resident who wrote these letters did not move away, but "disappeared" in this house, and she might be the next one to disappear.
