The sisters were playing on the riverside, but ran away when they saw Hae Mo-su (Korean: 해모수; Hanja: 解慕漱) approaching them.

After the sisters came into the palace and became drunk, Hae Mo-su attempted to block the exit, and was able to capture Yuhwa.

To solve the problem, Hae Mo-su summoned a chariot drawn by five dragons and went to Habaek's palace.

However, Hae Mo-su woke up in the middle of the journey, and ran away to Heaven alone by cutting the leather bag with Yuhwa's golden hairpin.

The king realized that she was the concubine of Son of the Heaven, thus kept her in a detached palace where the sunlight followed Yuhwa and made her pregnant.
