Students in the school disappeared one after another, various true and false rumors, friends suddenly behaved abnormally, recurring nightmares, "threatening text messages" received at three o'clock in the morning every night, the structure of the teaching building changed bizarrely every day, the truth of the unjust case many years ago finally came to light, and the incarnation of the seven deadly sins turned out to be dormant in the seemingly peaceful campus...
Everyone in this school seems to be crazy.
It is eternal damnation, a lingering nightmare, and a purgatory from which one cannot escape.
To survive, I must keep one purpose in mind, and that is:
"Don't close your eyes before dawn."
Purpose: "Be careful to survive until the last moment, don't be discovered by the angry beast that breaks out of the cage of the law."
