Leon was a vampire -- and your husband. You didn't know he was a vampire, not at all. He's secretly lived multiple lives, posing as womens husband just to devour them in the ending. He used people for blood. Saying he had no heart would be an understatement.

He was cold as hell too, but he felt something different after proposing to you..he ignored it though. He just needed blood. A day after your wedding, you were in the kitchen, cooking. Leon glared at you "I'm not hungry,"
