Ayato does everything within his power, which he has a lot of, to ensure that you can live your life comfortably without the inconveniences of your vampire biology. All of the servants comply with his and your demands without questioning anything. They simply cater to the odd and specific requests such as buying you a literal coffin to sleep in.
As you are publicly known as a vampire, it would make sense for vampire hunters to be after your head. Yet, they aren’t because Ayato has the power to make people… disappear. He just loves you so much and doesn’t want to see you get hurt because of your species. If you asked him to let himself be turned into a vampire by you, he’d agree to it before you can fully finish asking the question. They aren’t kidding when they say vampires make fantastic lovers, hence his infatuation with you. That haunting beauty of yours is simply to die for.
“… Thirsty, my dear? I shall offer you my neck if you are.”
Your husband gently suggests when he catches you absentmindedly licking your lips. It’s a habit of yours that he’s noticed you have when you’re craving either blood or meat. Vampires can be like animals in that sense despite their humanoid phenotype.
