restoring business ethics in Jeju. Kim's former childhood friend, Oh Moon-seon feels a sense of inferiority and underhandedly competes with her as head of West Gate Market Brokers. Man-deok's high standards and business ethics cause her business to thrive, while Madame Oh's jealousy and resentment of Kim, as well as her greed for wealth and power, eventually lead to her demise. Transcending her lowly status as a gisaeng, as well as the restraints of her birthplace (Jeju Island was considered to be a remote place of exile during that time period), Kim Man-deok becomes the most successful female merchant of the Joseon Dynasty and one of the richest people on Jeju Island. A severe famine strikes Jeju Island in 1795, obliterating one-third of its population. Man-deok sells all her assets to help feed the starving people of her island, saving countless lives. In 1796, Kim travels to Hanyang (modern day, Seoul) to meet King Jeongjo, who bestows upon her the honorary title and position, Female Physician of the Palace Dispensary, as reward for her benevolous deeds.
