There was a legend said that two Gods have broken the law of heaven. A goddess who lived in a light, fell in love with a god who rule the darkness. Despite both of them breaking the rule, heaven did not give them any punishment. They show other that light and dark can live in harmony. But their love end up in tragic. Some of the gods and goddess did not agree with their relationship. Before their love end, they made a promise that they will reincarnate in the other world, and heaven approved their promise. Both of them reincarnated as a human. One have a heart as warm as the light, the other one have a heart as cold as darkness. Their love will be reincarnated and truth behind their tragic love will be resolved.
