[The text is also in the first person]
I used to believe that every anomaly in this world could find a logical explanation.
Until I received a strange patient who said that he checked into a non-existent hotel room and met another "self" there.
At first, I thought it was just a hallucination caused by a perceptual disorder, but then I met several patients who seemed to share his condition, and then I received a package containing only a photo.
There is a sentence written on it: "Shen Qing, you have also lived in 407."
Intention: open that door
