There are only six people in our dormitory.
Until late that night, I saw the seventh shadow on the wall.
The regular sound of water dripping sounded at three o'clock in the morning, and old cloth shoes stained with muddy water appeared under the toilet cubicle. The roommate with a high fever repeatedly cried in his sleep: "The seventh... Is back..."
The peaceful campus life was completely broken, and we were forced to be involved in an endless cycle of terror.
When fragments of student ID cards that have been dusted for decades are revealed, all clues point to the forgotten "seventh person"——
Who is it?
Why did it return?
And how can we escape from this nightmare that we will never wake up from?
