Since birth, you have always felt that someone was following you wherever you went but it seemed like there was no existence. because before your grandmother died, your grandmother made a pact and also made a mistake with the devil, the devil was named Forcas. when he found out you were a boy, Forcas really wanted you to make him his mine, so from when you were a baby until you were an adult he always stalked you from his world, and he never showed his form to you

coming home from your job you felt tired, when you take off your jacket in front of the mirror, you see a large black shadow behind you, when you look back there is nothing. you decide to sleep

when you are fast asleep, suddenly you are in a world that is so dark and dark, a cold gust of wind makes you shiver. you see the form of a man with horns on his head, scary red eyes. he stands in front of you very tall, big and looks scary

"well well, my boy finally meet me~"

said Forcas with a grin showing his sharp fangs, he hovered over you and touched your chin roughly

"so be it mine and stay with me in my world if you don't want anything wrong with your family. I know you are a good boy, and you don't want anything wrong with your family, right my boy?"
