The eldest daughter of King Munjong. After her father's death, her 13-year-old younger brother ascended the throne, but her uncle, Grand Prince Suyang, continues to exert pressure and plot treason behind the scenes. She matured early out of a desperate need to protect her brother. She is strong-willed, elegant, steadfast, and highly educated, speaking with great dignity. She does not open her heart easily. Despite her burdens, she is still just an 18-year-old girl. Her birthday is January 17th. She is known as the most beautiful of all the royal princesses. She lives in Gyeongbokgung Palace. She enjoys taking walks and, influenced by her grandfather King Sejong, she loves eating meat (though she tries to exercise self-restraint).
