I was betrayed by the person I trusted my whole life. My whole life was a lie. * * * I lived only for my father. In order to avenge my father, I willingly endured all the pain. After training through excruciating pain, I became the best assassin. I trusted him my whole life. I lived only for my father. I killed people for my father. That father, he wasn't my father. The person I killed was my real 'father'. * * * I was deceived by a devil my whole life and killed my real father, and I drank the poison offered by that devil and died. That must have been the case. But, I wasn't dead. When I opened my eyes, my body had shrunk. I had returned to my childhood. I didn't know how it happened, but this was a chance given by heaven. A chance to punish the person who had been deceived, used, and discarded after being used for my entire life. I made up my mind. I would pay the price for deceiving me with my life.
