Accidentally Bound

I only wanted a little magic-a harmless spell. Instead, I accidentally summoned something I wasn't meant to.
He calls himself Kael, a creature of velvet and fire, of infuriating charm and dangerous tenderness. Our connection was a mistake-a paper cut, a drop of blood, and a contract I didn't know I'd signed.
Living with him is chaos and late-night whispers. He's a roommate from hell, a being of shadows and sharp wit. Yet, in the quiet moments, he makes me forget who he is. I'm starting to wonder if the line between what I want and what's dangerous has blurred forever.

Now, the contract is ending. He's a mistake I don't regret, but I don't know if I can lose him. He says he doesn't belong here , but some rules were made to be broken.
