In the eyes of others, Lin Xi is just an ordinary office worker, living an ordinary life.
But she knows that this city has many invisible rules——
Don't look in the mirror at three o'clock in the morning;
Don't step on the seventh puddle on the road on a rainy day;
If you hear someone calling your name at night, don't look back...
Once you violate it, you will be targeted by "them".
Lin Xi's daily life is to carefully abide by these rules while trying to find out the truth behind them.
Until one day, she discovered that these rules might be alive, or even——
They were staring at her.
