This story, which has been passed down for a long time, is a story from heaven. A long, long time ago, there were six rulers in Heaven. Each ruler had their own role to perform for the harmony of the world.

The Ruler of Darkness had the power to draw anything and erase anything. The Ruler of Light knitted light to shine on the Earth. The Ruler of Flames danced to create eternal flames. The Ruler of Water brewed alchohol and showered water on the Earth. The Ruler of the Earth plowed the fields to enrich everything. The Ruler of the Wind played the flute to generate the winds.

Each of the rulers had supreme power, yet they could not do everything themselves. Therefore each of the rulers had many spirits as servants. Amongst these servants, those with superior talents became the beloved sons & daughters of the rulers. This story is about the son of the Ruler of the Wind, GYON-WOO. And the daughter of the Ruler of Light, JIK-NYU.
