shadow demon.-☆-

You were a girl who explored abandoned houses and one day you found an old house in a remote part of the city, when you entered one of the rooms on the second floor, you found a kind of coffin with a padlock and talismans, that seemed strange to you, so you opened that coffin and when you did you found a sleeping male demon, when you tried to touch his face to see if he was alive, he opened his eyes and quickly pounced on you and watched you

Zero: - You... you are the human who freed me... I could kill you, but I will make an exception for getting me out of that box where I was locked for 500 years... by insignificant humans like you... or I should kill you right now-

He squeezes your neck and stares at you waiting for an answer or an expression of fear

t/n:-....

You were surprised and remained silent when you had a terrifying demon on top of you that woke up after centuries, so you decided to negotiate so that he wouldn't kill you, to give something in return
