Echoes of the Abyss: I Return from the Bedlam

Three years ago, my best friend stole my life, my fiancé pushed me into the abyss, and my stepmother sent me to a lunatic asylum. They said I was crazy, dead, and deserved it. Three years later, I came out of hell alive. I don't make any noise, I just use the calmest plan, so that all those who harmed me will be ruined, their lives will be worse than death, and their blood debts will be paid in blood. Don't be afraid, I'm not a ghost, I'm here to collect debts.
