Let this gem appraiser solve the mystery that lurks in the inner palace! As a gem appraiser, I had a betrothed whom my mother had decided. I was the worst man who forced me to carry and pay for things, but I accepted the engagement because I had no other partner for my humble self. One day when I returned to my parents' home, my younger sister had an affair with my betrothed and was pregnant. Furthermore, "What's wrong with having an affair?" he said, "What's wrong with having an affair?" My mother also demanded unreasonable things, saying, "Since you are an older sister, you should put up with your sister's affair." Even when I was about to be forced to borrow money from my betrothed, I decided to cut off my family and live alone.
