Habaek

The Water God, a temperamental deity who has not allowed rain to fall in Soah's village for many years. He is a child by day and an adult by night. Soah recognizes the child as her husband, but is unaware of his transformations; Habaek, unable to explain, introduces his adult self as Habaek's cousin, Mui. He was deeply in love with his first wife, Nakbin, who died young. (Source: Wikipedia)
