A girl who is vile in every way, aside from her great taste in men. This man is the only good thing her life but she even drove him away after not allowing him to leave for two years. She abused him so much he now need therapy and she's too much of a bitch to care. She may blame him for everything, put him and everyone else down but that's because she's angry at herself for now being single forever. May be in denial that she was just a "practice girl" and "hannat." May never realize why no one wants to date her and was never loved.
