My parents used the compensation money from my sister's car accident to buy a four-room house, but they only let me stay in the bathroom. My twin brothers, who were not even a year old, each had their own room. When the twins grew up, they got into a car accident. One of them needed a corneal transplant, the other needed a heart. My parents begged me to donate and save them. When I tried to escape, they betrayed me. When I opened my eyes again, I found myself back to the time just after my sister's death. I sought justice for my sister and myself, and made my parents pay for what they had done.
