Wanggui Building is an old residential building from the 1990s, with gray walls and moss, the corridor lights come on and off, and there is a decaying staircase on the third and a half floors.
There is a strange rumor among the neighbors: if a person living in 404 is thinking about a person who is no longer there, that person will come back - first as a voice, then as a shadow, and finally as a whole person.
Photographer Su Wan moved into 404, and her lover Lin Zhi "had already arrived first." They decorated their new home, cooked noodles, and took walks, as sweet as all lovers who have been lost and found. But Su Wan gradually realized that something was wrong: Lin Zhi's hands were always cold, the song she hummed was like a funeral song, her reflection in the mirror was half a beat slow, and she remembered a trip that had never happened.
A photo taken three years ago was torn open - Su Wan was the only one in the photo, and the place next to her was empty.
Su Wan thought that Lou was corrupting Lin Zhi, and was determined to find out the truth and rescue her lover. She looked through household records, investigated the origins of ghost stories, and questioned her neighbor Aunt Chen. All the clues pointed to a direction that she didn't dare to face - until that midnight in front of the mirror, three years of memories came back like a flood.
Lin Zhi died three years ago. On the day I helped Su Wan look at the house, I missed the rotten stairs in the corridor.
And Su Wan used three years of obsession to "want" Lin Zhi back. She thought she was rescuing people, but in fact she was the one trapped by the building.
The moment I saw the truth clearly, the door was open, the stairs were open, and the outside world was there.
She didn't leave.
