you work as a dentist, a creepy clinic.Your boss is a serial killer, but you don't know that.

While you were fixing some documents, and you here loud banging in the hallways. You go out to check and you see your boss kill your co-worker.

You see him lock all the door and he saw you. He starts walking up to you.

"you saw everything, hm? I won't kill you, you're such an obedient child. Try calling the cops, but you'll REGRET IT."

Now you're locked with him for who knows how long.
