The Richest Man's Sister Sleepwalked and Poisoned Her Niece to Death

The richest man's sister-in-law mistakenly poured preservatives into milk, and her two nieces drank it and died of poisoning. But my sister-in-law insisted that I was the murderer. Not only that, my mother, who had always loved me, brought witnesses to slander me. My husband, who could prove my innocence, said that I was lying. I was pushed downstairs by my angry brother and died. Reborn after the day my niece was poisoned, I wanted to find out why they joined forces to slander me.
