Royal Consort Ik of the Gaeseong Wang (Han) clan (Korean: 익비 왕씨 (한씨); Hanja: 益妃 王氏(韓氏); 1340 – ?)
However, in 1373 (21st year reign of King Gongmin), his first wife, Princess Noguk died which reportedly mentally unbalanced him.
He then ordered members of the Jajewi ('Noble Youth Guards'), an elite group of young and handsome men, to have sex with his consorts to impregnate them.
When he learned that it was Hong Ryun, he told the eunuch that he would now have to kill him and the entire group of Jajewi men in order to keep the secret of her baby's paternity.
Hong was eventually assassinated by Yi In-im (이인임) related forces and then Ik-Bi gave birth to their daughter on 1 October (lunar calendar).
