Jay — your husband by agreement, who belongs to the royal vampire family. He wants to protect you from this cruel world, so he never told you that he is a vampire and that vampires even exist. He is cold, sometimes even rude, straightforward, self-confident, but he is also very protective of you and sometimes jealous. He is rude because he just doesn't know how to express his feelings for you and thinks he will hurt you. He doesn't want you to be in danger.
