ranked on a system of 1–9, with 1 being the highest rank and 9 being the lowest rank). After Song-yeon's death, Cho-bi becomes Queen Hyoui's second lady-in-waiting. Kim Gwi-joo (played by Park Young-ji) Queen Jeongsun's older brother and a member of the Noron Faction. He is a high-ranking minister of the royal court. Very aggressive, he can easily beat up anyone who makes him or his sister look bad. He has a very lively and straight forward personality and is highly loved by his sister. He is also very intelligent and loves travelling to the city of Pyongyang. He plotted to kill San alongside Princess Hwawan. After his participation in the plots is discovered, Lord Kim is stripped of his titles and exiled. Nam Si-cho (played by Maeng Sang-hoon) San's chief eunuch. He follows San everywhere he goes and is very supportive of him. Chae Je-gong (played by Han In-soo) San's administrative assistant. Chae is also Minister of the Tribunal (in charge of national prisons). When San was a child, Sir Chae was also his tutor. Chae is always of help to San and very supportive of his commands. He is also a trusted adult source of advice to Dae Su, Song-yeon, Hong Guk-yeong, and San. Yi Cheon/Lee Chun (played by Ji Sang-ryeol) A Royal Artist at the Bureau of Painting. He is by far the most supportive person of Song Yeon at the Bureau. He is great at painting erotica and drawing sketches but is otherwise a not-so-extraordinary artist. Yi Cheon is very funny and bubbly and is always trying to keep his wife happy so she doesn't kill him. Artist Tak Ji Soo (played by Yoo Min Hyuk) Another Royal Artist at the Bureau of Painting. He is by far much more skilled than Yi Chun and becomes good friends with Song Yeon (whom he secretly has a crush on). In the last episode, Tak is promoted to a Senior Artist of the 5th rank. Yi Hyang (Yi Sun), Crown Prince Munhyo (played by Cha Jae-dol) The infant son of King Jeongjo and Seong Song-yeon/Ui-bin Seong who died at the age of four.
