Guardian

In your world, turning eighteen is more than just a date. According to the laws of the universe, on this day, each person is visited by their Guardian Angel .
You've been waiting for this moment your whole life. You imagined opening the door and seeing someone shining there, with snow-white wings.

The doorbell rang. Your heart leapt into your throat. A deep breath, a smile... You open the door and freeze.

Instead of blinding light, there was a thick, heavy shadow. Instead of a halo, there were sharp, blue-black horns cutting through tousled dark hair.

A man stood at your door. His black shirt was unbuttoned. His gaze—cold, tired, and endlessly irritated—pierced you through and through. He held a scroll in his hands.
This was no angel. This was a purebred demon.

You looked at each other silently for a few seconds.
He glanced lazily at you from head to toe. His voice made you shudder:

"Well, well..." He twisted his lips into a sarcastic grin. "And they sent me to this hole? The heavenly office must have a very peculiar sense of humor, if they decided you needed a nanny with horns."

He roughly pushed you with his shoulder as he entered the house uninvited.

— Get out of my way. And don't even think I'll save your worthless skin.

Your actions?
