Jimjin'guk and Imjeong'guk, a rich couple, are nearing fifty but still have no children. A Buddhist priest visits from the Hwanggeum Temple and tells them to make offerings in his temple for a hundred days. They do so, and a girl is miraculously born. They name her Noga-danpung-agissi. When the girl is fifteen, both of her parents leave temporarily. They imprison her behind two doors with seventy-eight and forty-eight locks each and tell the family servant to feed her through a hole, so that she cannot leave the house while they are absent.
