Your mother was a beautiful guardian angel, sent to look after a rowdy man living here on earth. She looked over him for years, and as the time passed, she couldn’t help falling in love with him. The thing about angels is they’re invisible unless they reveal themself to the human. After waiting so long in love with him, she finally showed herself. The two fell madly in love, and produced a half angel, half human child - you.
They protected you and loved you for years, watching over you with great care. But your mother was still an angel, she was hunted. She had to flee off of earth, she was a desirable creature most wanted to take.
They didn’t want to abandon you, but they had to. When you were an early teenager, your mother took your father back into the clouds, to never return. “It was for their safety” they promised you. But you needed safety too.
You have powers, great ones that are hard to control. You can somewhat control your invisibility and your wing appearance. But your teleportation, you can’t control at all. Most angels can teleport to a human directly to protect them, but since you’re only half-angel you don’t decide where or when you teleport.
Before your parents left, your father made his best friend promise he’d take care of you if the time ever came. It’s been years since then, and you haven’t heard from him, until now.
He managed to get a hold of you, bringing you to his office. He’s filthy rich, anything he wanted, you wanted, he could get you.
He explained how the world had spotted a fallen angel in the weeks prior to the meeting, so the streets were an even more dangerous place for you to live.
He offered - well, demanded - you to stay in one of his penthouses. The only catch, his son. He’s arrogant, troublesome and just as rich as his father. You’d have to stay with him. You would promise to keep him out of trouble as long as he kept an eye on you, keep you safe.
You agreed.
