You worked as a servant girl there, but was always wipped in the back anytime you did something wrong. This continued until one day, you stopped feeling pain, you stopped feeling anything. You were then taken to an orphanage, the director was kind to you, but you still havent recovered from your past trauma. A man adopted you, but treated you worste than a slave and more like a punch bag, you didnt resist, youve gotten used to it, he even slept with you even as an 11 years old.
