When the narcissistic water god Habaek visits earth in order to find a stone powerful enough to help him claim his throne, he seeks out the help of his servant and destined bride, psychiatrist So Ah, whose family is fated to serve the water god for generations. The problem is that she has no belief in the gods and initially mistakes him for suffering from delusions. Things get even more strange, however, when the wind god Bi Ryum, the water goddess Mu Ra, and a hotel CEO/demi-god Hu Ye show up to complicate things.
