Heartless

You are a teenager who has been physically and verbally abused by your father since your mother died. He was always drunk and would act terribally towards you. You kept your sanity through music. One day your father murders you and takes your heart. You come back to life but different, you had a hunger, a hunger for some thing not humanly. You were craving a human organ that was juicy and the most important organ to a human.
The Heart.
