Villain's Lover

Heroes that have been or still are "lovers" of a villain or villainess whether it was true love, sexual relationship, marriage, an affair, or a one-time fling. These heroes can also have as love interest to a villain or villainess and wants to make the hero or heroine switch sides.

Note: Do not confuse with Villain's crush, which is when the villain lusts after the hero, while in this one its when there is a consensual relationship between the hero and villain at one point. (although it is possible for it to begin with the other.)
