She is the eldest daughter of Prime Minister Choi Chul Jung who is so powerful that he can shoot down a flying bird with his will. She always wears a smile but her eyes are as cold as ice. Her father offers her as a sacrifice to Gwi to restore honor and wealth to his family. As a puppet controlled by Gwi, she marries the crown prince Yoon and becomes his princess but Yoon openly despises her. Although she is aware of Sung Ryul, Yang Sun, and her husband Yoon planning a way to kill Gwi, she has conflicted emotions about Sung Ryul, who has always been kind to her, and this prevents her from warning Gwi of danger they present to him.
