Unloveable
Whatever Kayne had experienced in the past left him psychologically scarred. Being so accustomed to cruelty and abuse, he had begun associating human contact with pain. When Monica first touched him, his cries were an expression of expecting to be hurt.
Kayne wasn’t anti-social or dangerous. The abuse he suffered had made him live in constant fear of being harmed. He believed himself unloveable and didn’t know what it felt like to be petted or shown affection like a normal dog.
