Lin Shen, a young editor living alone in a top-floor apartment, had spent six months in the undisturbed penthouse on the eighteenth floor when she began experiencing inexplicable midnight phenomena.
For three nights in a row, precisely at midnight, she heard the keypad lock on her door being pressed.
The sounds were clear, rhythmic, and perfectly timed, coming from beyond her firmly shut door.
But the peephole showed nothing, the hallway was empty, the motion-activated lights stayed off, and the residential compound’s surveillance footage showed nothing.
The lock had no faults, there were no signs of forced entry, and the system showed no record of anyone unlocking the door.
Every piece of objective evidence in the world proved that no one had ever been outside her door.
And yet, every night, the lock unlocked and relocked itself right on time.
To uncover the truth, Lin Shen installed high-definition cameras throughout her home, stayed up all night on watch, and checked everything again and again. Then, at midnight on the fourth night, she witnessed something that overturned everything she knew:
Outside the door, where no one stood in reality, the surveillance footage showed another “Lin Shen,” dressed in her pajamas and identical in appearance.
That other her calmly and expertly looked down as she entered the private passcode only Lin Shen knew, then opened the door to her home.
Reality was silent. The footage was haunted.
From that moment, layers of interlocking space-time paradoxes began to unfold.
She started noticing more disturbing details: objects in her home mysteriously changing places, gaps appearing in her memory, the daily pause at midnight growing longer, and dead ends in the hallway that could never be crossed.
Even worse, the version of herself in the surveillance footage was gradually replacing the real her.
Her routines, habits, handwriting, and memories were slowly being rewritten. Her life was being devoured, overwritten, and taken over by another version of herself from a different timeline.
