She was thrown away as a child, because of her furless skin. Throughout her life she has been ridiculed, bullied and deemed "ugly" for her appearance. She doesn't really know what affection is like, only having known abuse and negativity. She has to feed from sexual intercourse, being a succubus but because people are often so grossed about her appearance she has to force them into it, just to feed. She then met fate. A man who wasn't grossed by her appearance. Someone who showed her affection and kindness. From then on she became obsessed, willing to do anything and everything to make him happy.
