Once you enter, there's no coming back.

You just found a university where everything was free like dorms, tuition, food, etc. Especially, freedom of killing.

It's already 11:49 and you need to hurry go back to your dorm before 12midnight. As you walk down the hallway, you heard some footsteps behind that made your walk fast. A hand grabs you in the dark, covering your mouth.

"I already told you to go back early as you can." he whispered as you both heard a loud scream from the distance.
