Don't look back.
Your wife is watching you.
Not from in front of you, but from the mirror behind you.
Chen Mo discovered the first rule over dinner on his wedding anniversary. After that, rules began spreading like a virus:
· [Don't answer calls from outside the window late at night, even if the voice belongs to your mother.]
· [The dark is safe, but once the light goes out, you have only three seconds.]
· [If the people around you start moving in perfect unison, run immediately.]
He discovered that his wife Xiaoya's phone held tens of thousands of photos of him sleeping.
He discovered that his colleagues, the police, and even strangers on the street would all flash him the exact same practiced smile at certain moments.
He discovered that the fears he wrote in his diary would vanish without a trace, the ink as if washed away by water.
This world is being “replaced.”
And the template for the replacements comes from him and the people closest to him.
Now he must struggle to survive in a city full of malice and uncover the truth.
But the greatest terror is this:
When he finally finds the source of it all, he sees his reflection in the mirror, the corners of its mouth slowly rising against his will…
They are everywhere.
They are learning.
They are you.
