My sister was contacted by the company where she worked from the consumer finance sector and decided to quit her job. The reason was that my brother and I, who lived together, owed a large sum of money. However, my sister still worked like a robot at the convenience store to pay off her brother's debt. The debt and fatigue gradually eroded her spirit, and when everything became meaningless, my sister became a convenience store saleswoman for a man who had sex with anyone, anywhere.
