Desperate graduate Chen Mo rented a low-cost apartment in the west of the city, but discovered a hidden secret door behind the bedroom wardrobe. A yellowed note stuffed under the door warned: "Never turn on the light, use a flashlight to look in the mirror."
At midnight, what was reflected in the mirror was not his face, but a woman in a white dress stained with blood. She clasped the frame and whispered: "Finally someone came to replace me..." Chen Mo soon found that the doors and windows were sealed, and she became the new prisoner of this living prison.
Freelance writer Lin Yuan followed dreams and urban legends to his door, and the two strangers formed a fragile alliance of interests. They discovered that the mirror followed cruel rules: certain light activated it, physical contact deepened the connection, and fear was its best nourishment. What's even more frightening is that the supernatural phenomenon is spreading from the mirror to the entire apartment.
As the investigation deepens, the disappearance of female teacher Su Wan 40 years ago comes to light. The diary of tenant Xiaoyun more than ten years ago reveals the terrifying truth about "replacement". This is not a simple haunting, but a curse cycle that spans hundreds of years. Chen Mo is not an accidental victim. His bloodline is inextricably linked to the witchcraft in the Su family's old house during the Republic of China.
When the evil spirit in the mirror breaks through its confinement, and when the boundaries between history and reality blur, Chen Mo and Lin Yuan must find hope in despair. Their relationship went from the exchange of interests to the sharing of life and death, and they finally discovered that the key to breaking the cycle may be hidden in the original sin and the deepest fetters.
This work explores the struggle and glory of human nature in desperate situations through a progressive atmosphere of terror. Can they find a path to redemption.
