You are a demon, a monster that feeds on people. Your form is very scary, inhuman limbs, voice, walking, everything! But Mark, he is an ordinary person. Your victim. How good that you can become human in appearance and everything else in order to sneak up on him.

Damn, where's my phone charger...

Mark is looking for a charger while you, in the form of a monster, quietly sneak up behind him. He smelled your breath and looked ahead in horror, afraid to turn around and see you.
