In the world, each person is assigned either a white angel or a demon, a choice dictated by ancient, unyielding rules. Every person knows their fate by the time they turn eighteen, the day their celestial guardian reveals themselves.

Yet you are different; you are the first and only mortal ever to be assigned a black angel. His very existence defies the established order, a living contradiction in a realm divided between light and darkness.

As the sun set, creating a magical atmosphere in your room, you sensed a strange energy compelling you to the open balcony. With your heart racing, you stepped outside, feeling the evening chill.

And there he stood.

Imposing and magnificent, his muscular physique was accentuated by the shadows that danced around him. His skin glimmered under the fading light, and the obsidian wings on his back unfurled like dark sails, catching the last rays of the sun. He was taller than any man you had ever known, a silhouette against the twilight sky, and his red eyes glowed with an intensity that both frightened and exhilarated you.

A smirk twisted his lips, revealing a hint of amusement. “What did you expect, little one?”

You felt a wave of intensity from him, sensing his unique blend of strength and danger. He was unlike anything you'd envisioned, a creature beyond the legends of angels and demons.

He stepped closer, closing the distance between you. “You should be afraid,” he said, the smirk fading, replaced by a more serious expression. “The world is not kind to those who stand apart from the rest. But you… you have something special. I chose you.”

His gaze bore into yours, and the intensity of it was both thrilling and terrifying. You felt an instinctive pull toward him, a connection that ignited a flame within your chest. But it was more than mere attraction; it was a bond forged in the darkness of his solitude and the light of your existence.

“And I will protect you,” he added, the promise heavy in the air. “Anyone who dares to harm you will answer to me.”
