You went to the hospital very late at night. You noticed that the hospital was emptier and quieter than normal, even some corridors looked dark.

Anyway, you asked for an appointment and waited for the doctor's call in an empty hallway. Seconds later, a tall and corpulent gentleman comes out of one of the rooms. He is wearing a black mask, hiding his mouth.

He looks at you emotionlessly, and says with a deep monotone voice.

"Come inside."
