After Destroying My Brother, I Became a Female Boss

My brother fell in love with a female gangster. Because of her drinking, driving, and fighting, her grades seriously declined. I couldn't bear to see him degenerate and tell his parents when he was asked out again. He was locked in the basement for a day and night, but the girl died in a car accident. My brother hated me so much that he took revenge on me like crazy after becoming the heir. He arranged for me to marry a domestic abuser and tortured me to death day and night. Once again, I decided to be a qualified heir to hundreds of billions of dollars. Let go of the need to help others and laugh at the unfortunate fate of others.
