The princess was born in 1130 during her father’s 8th year of reign. In 1151, alongside her younger sister, Princess Yeonghwa, they formally became a princess (궁주; 宮主).^[1] Then, she married her paternal aunt's son, Wang Seong the Marquess Sinan (신안후 왕성; 1146–1178).^[2] Because they were descended from the same ancestor, the princess was also Wang Seong's paternal fourth cousin.^[3]

They later had a daughter, the future Queen Wondeok (원덕태후 류씨; 1161–1239), who married King Gangjong, and had two sons: Wang Won the Marquess Gyeseong (계성후 왕원; 1163–1240) and Wang Jin the Marquess Yeongin (영인후 왕진; 1165–?), who would become the father of King Huijong's second wife.^[4]

To honor his deceased maternal grandmother, King Gojong reduced the number of palace's side dishes and ordered his officials to wore mourning clothes for a day.^[2] Meanwhile, Wang Seong died in 1178 (8th years reign of King Myeongjong) and suspended the inquiry for three days.
