She later married her second cousin, Gojong of Goryeo and changed her clan into Yu (유씨).
Her mother-in-law, Queen Wondeok was initially her aunt and the daughter of Princess Changrak who also changed her clan to Yu.
The then-military ruler Ch'oe U gave her a coffin made of gold and silver.
After her death, Gojong didn't remarry again, so it was presumed that they had a good relationship both as cousins and spouse.
She then received her posthumous name and honoured as Queen Mother (태후; 太后) after their oldest son ascended the throne as King Wonjong in 1260.
