Since the princess changes her name as KUNG YAN SO; no one knows about her real identity. Hence, she is charged and punished by NIN to carry out social work in the community. It is a tough job for a woman to do construction work, especially the princess. However, the princess has a chance to realize the hard time of her citizens directly. It is not just about the hard work; YAN SO also has difficulties in adjusting her request on food. At last, she finds the fast food shop owns by CHUEN and orders a lot of food at once. After finishing the meal, YUEN asks YAN SO to leave early because he knows that they do not have enough money to pay the bill. Therefore, YAN SO trades in her belongings at the pawnshop; while the receipt is dropped and picked up by CHI coincidentally.
