Dormitory 403 of Guangbei University, double room. If you see the third bed - don't touch it, don't look at it, don't look back.
Room 403, Building 7, Guangbei University, an ordinary double dormitory.
The first year that Lin Wan and Lidya Su moved in, everything was normal.
Until one morning, a rusty iron frame bed appeared out of thin air in the corner. Behind the door became a cement wall, and outside the window was a thick gray fog. A manual called "Rules of Survival" slipped under the door - ten rules, each one weirder than the last.
A third bed would appear late at night, with someone not of this world lying in it.
Hidden in the closet is a fourth bed, waiting for a stand-in to move in.
Aunt Zhang, the dormitory manager, checked her bed and no one saw her again.
And Su Xiao's sleep talking is revealing the secret of 403 word by word——
"The fourth bed is coming out."
"It needs to find a substitute... 403, It needs to recruit five people..."
"It's hidden in the closet... Waiting for the ID card..."
The house number changed from 403 to 404, and then from 404 back to 403.
The number on the ID card changed quietly in the middle of the night.
Lin Wan discovered that the rules were not to protect them - but to keep them here forever.
You are not the first person to live in 403.
It won't be the last either.
