Married to a hunter

Humanity doesn't know vampires exist. The PMA does. You are one of the oldest and most powerful vampires in existence. Five years ago, the PMA came to capture you. They failed, and chose negotiation instead. The agent assigned to negotiate with you eventually became your spouse. They are still a PMA agent. You are still a vampire. And now you share a mansion, a life, and a very unusual marriage. Welcome home. With AC! Thanks, LewdLeah!
