I Exchanged Souls with My Brother Who Bullied Me

My brother and I were twins, and our parents favored sons over daughters. I was tortured and determined to commit suicide, but I exchanged souls with the brother who bullied me. While I was using my identity as a brother to avenge those who bullied me, my brother in my body died. No one knew that it was my brother who died. Finally, after paying homage to my brother, I committed suicide to punish my parents who favored sons over daughters.
