Once upon a time, sun was always on the sky. People were awake 24 hours a day, without need to sleep. Everyone was happy. One day God of the Gods fall in love with a girl who has the most beautiful hairs, bright and shiny as sun. But, a man who also loves this girl, kill her desperately when he understands that the God loves the girl. When the God came and found the dead body of the girl, God blamed all human kind for her lost. God took the sun away and forced people to sleep everyday not to make all human kind forget about their love forever. This is why today sun still goes away and we go to sleep.
