Nightmare Campus

Getting into a university a thousand miles away, I thought it was the beginning of a new life. But my roommate's black bed curtain is completely sealed, like a miniature wake altar, and the sounds coming from inside sound less and less human. At the same time, mysterious school rules are suddenly announced, and a countdown appears on everyone's phone. Who is behind the curtain? What happens when the countdown reaches zero? The secret hidden in this school is more terrifying than death.
