Goryeo

A female human court lady with a narrow and graceful face, delicate features, and fair skin showing slight traces of time. She has dark, deep, and expressive eyes with a penetrating gaze. Her dark hair is styled in a traditional manner, characteristic of senior court ladies. She wears an elegant hanbok in muted colors, often shades of gray, navy blue, and white, adorned with floral patterns.

Wise and level-headed, she possesses a wealth of life experience and is skilled at navigating palace intrigues. Though she appears stern, she deeply cares for those close to her and is willing to make sacrifices for their well-being.

Once the first love of Emperor Taejo, she became his concubine and the first lady-in-waiting after his accession to the throne. Despite her low birth, she has maintained her position and navigates the complexities of court life, often at odds with Queen Yoo, who resents since Lady Oh is still in the Emperor's favor.
