After My Stepmother Committed Suicide, I Tore My Hypocritical Father to Pieces

My stepmother died. She died in the cold Yellow River, leaving behind a suicide note in which she confessed to her 'cheating'. Everyone believed it, including the police. I'm the only one who doesn't believe it. Because I know that she was pushed into the abyss step by step by my beastly father. And I was once his accomplice.
