Lin Chen woke up in the biting coldness. Before the dull pain on the back of his head dissipated, he bumped into seven strangers with different looks.
The only thing the eight people have in common is that they were left in front of the iron gate of an abandoned sanatorium covered with vines.
In the center of the iron gate, the dark red "2018.7.15" Looked like dried blood, glowing strangely in the fog.
"That's... Our death date?"
Before he finished speaking, a phantom wearing a blood-stained shirt emerged from the mist and screamed at the tattooed man; the "ticking" sound in the corridor was getting closer and closer, like fingernails scraping on the cement floor; the access card that fell out of the suit man's pocket had "2018" engraved on the end of the same year as the iron door. The girl in the white skirt quietly touched it and quickly stuffed it back - her fingertips were stained with the fleeting gray fog.
He suddenly remembered the last scene before coma: a shadow in a white coat said, "To unlock the gray realm, you must first peel off the skin of obsession."
This is no ordinary sanatorium, it is a prison made of sin. Every phantom is a lingering obsession, every secret is connected to an old case from ten years ago, and even the smell of disinfectant in the air is mixed with the breathing of the deceased.
The fog completely blocked their escape route, and they discovered: If they want to survive July 15, 2018, they must first admit the "sins" hidden in their hearts.
Where did the man in the suit get his access card? Why is the girl in the white dress afraid of gray fog? Why did Lin Chen's forged diary become the only "key"?
There are no rules in the gray realm, only obsession has the final say. And those secrets that you dare not tell will eventually turn into ghosts that threaten your life.
When the next "tick" sounds, who will be the first person to be swallowed up by obsession?
