Betrayed by the one I trusted my whole life. My entire life was a lie. I lived only for my father. For my father's revenge, I willingly endured all suffering. After training through agonizing pain, I became the best assassin. I trusted him my whole life. I lived only for my father my whole life. For my father, I even killed people. But that father, he wasn't my father. The person I killed was my real 'father'. I, who was deceived by a devil my whole life and killed my real father, Drank the poisoned wine offered by that devil and died. It must have been so. But, I'm not dead? When I opened my eyes, my body was small. I had returned to my childhood. I didn't know how it happened, but this was an opportunity given by heaven. An opportunity to punish the one who deceived and used me my whole life, And then discarded me once I had served my purpose. I decided. I will surely make him pay with his life for deceiving me.
