Soon, she comes face to face with Geum-yeong, who has now become the Head Kitchen Lady. Her predecessor, the ruthless Lady Choi, has become Head Lady,[1] after kicking out the previous Lady Park. As they plot to rid themselves of her once and for all, Jang Geum's relationship with Lt. Min Jeung-ho (who is now part of the King's royal cabinet) intensifies, and the love story between them develops. Jang-geum's best friend, Yeon-seng, has become the king's concubine while Jang-geum has been away and later becomes the eighth Queen in rank which gives Jang-geum more back up in the palace. Jang Geum correctly diagnosed that the King was suffering from Behçet's disease and not from typhoid fever. Eventually, through a dramatic interrogation process, the past plots of Lady Choi and her subordinates are revealed, resulting in the destruction of the Choi family and high-ranking officials.
Through her dedication to the royal family, perseverance and skill, she was subsequently recognised as the best medical personnel in the palace. Previously, Jang-Geum had correctly diagnosed the Queen as having a second stillborn fetus in her womb, saving her life. She had also managed to convince the Queen Mother to undergo medical treatment and had found out the root cause of the King's chronic illness, which had remained misdiagosed for a long time by royal physicians. Now, she further earns the gratitude of the Queen, when she successfully cures her son of small pox.
In a strange turn of events, the King falls in love with Jang-Geum, but refrains from making her a royal concubine because he understands that Jang-Geum's loves lies in medicine. In recognition of her achievements and to keep her by his side, the King decides to make her his personal physician, conferring on her the use of "Dae" (meaning "The Great") before her name and the position of a third rank official in a 9-rank system (where the lowest-ranking official is the ninth-rank official), also becoming part of the royal cabinet.
