Byun Soon, Dael Soon and Hae Soon were three sisters. One day, a tiger came to their house. The girls were frightened to see the tiger. They ran out of the back door and climbed up a tree. When the tiger began to climb up the tree, the sisters prayed to the god to save them. Their prayers were answered. An iron chain descended from the skies and the sisters climbed up to safety. They lived happily in the land of the gods. In due time, Byun Soon was transformed into a star, Dael Soon into the moon and Hae Soon into the sun.
When Hae Soon set out across the skies on her first day out as the sun, people on earth came out of their homes to stare at her. Hae Soon was an extremely shy girl and she turned pale with embarrassment when she saw the people looking up at her. The more they stared, the brighter she became, till she became so bright that the people were blinded by her radiance and could no longer look up. This suited the shy Hae Soon and she continued to glow brightly from then on.
