The Restaurant Owner's Revenge

My sister-in-law ate for free at my restaurant, running up a bill of 500,000. When I asked her to pay, she tore up the bill, calling me an outsider. I sold the restaurant. She later booked an engagement banquet, ordering 1.5 million worth of food and drinks, not knowing the restaurant had a new owner. She was drowned in debt, her engagement called off. I divorced my husband, moved to a new city, and opened a new restaurant.
