Royal Consort Suk-Bi of the Choi clan

Royal Consort Suk of the Choe clan (; fl. 14th century), personal name Choe Yong-deok was a Korean Royal Consort as the 4th wife of King U of Goryeo.

Biography Yong-deok, also known as Kayaji , was the daughter of Choi Cheon-geom and his concubine. Born into the nobi class, she worked in the Tongjewon before becoming a palace lady in the service of Royal Consort Ui of the No clan. In the 10th year of King U's reign, the king began to visit her daily and lavish more attention on her than her mistress. After court eunuchs pointed out that Yong-deok's home was too small and shabby to host the king, it was arranged that Yong-deok would live in the house of a courtier nearer the palace. Soon after his promotion, her father used his position to confiscate other people's homes

Yong-deok had not been invested long when she grew jealous of the amount of time the king was spending with another nobi woman, Bong-gai. She told the king that Bong-gai had previously been involved with a courtier, whom the king promptly banished to oversee construction works in the west.

Banishment In 1386, Yong-deok lost the king's favour. One day, she had her servant play the geomungo, but they stopped playing as soon as the king arrived. The king grew angry and beat the servant, asking why they had stopped playing. Yong-deok hugged his waist, saying "I've lost the king's favour and have nothing to do, if you keep beating the servant, what else will I have?" King U then punched her in the face. Princess Suknyeong accused the consort and her mother of attempting to manipulate the king through sexual practices, so King U expelled Yong-deok from the palace to her father's house. Her palace staff were imprisoned and interrogated harshly, whilst her father and his wife were also imprisoned and their house confiscated. Shortly after, Yong-deok was banished to Jeonju with her father, and her mother, elder sister, and four servants were executed, despite attempts by several courtiers to save them. One person on their day of execution said that they would be revenged on the one who killed them. The body was displayed in the city, and when King U went to view it, he ordered that it be spread on a cart to accelerate decomposition. The smell reportedly filled the entire street, and people did not dare to go near the body.

Reinstatement as consort In 1387, Yong-deok was summoned back to Kaesong from Jeonju. Although the Goryeosa does not specify whether her father accompanied her, he appears in a record dated one month later, receiving an appointment as Cheonyang Buwongun . and later pardoned her of all crimes when she fell ill. A residence named Uihyebu was established for her, and it was furnished in accordance with the arrangements of Queen Mother Myeongdeok's residence.

After U of Goryeo's deposal In 1388, King U was deposed during a mutiny by the military leader Yi Seong-gye, and his young son by Royal Consort Geun was put on the throne. As the mother of the new king, Royal Consort Geun was permitted to remain in the palace, but Yong-deok and the other consorts were expelled, along with their fathers, to their original homes. A few months later, on the occasion of King Chang's birthday, the remaining fathers of other consorts were released from prison.
