A doctor and inventor in the Water Kingdom, a relatively recent inhabitant to the realm. He appears cordial and at times comic, but is perceptive and secretive. He appears to have his own motives regarding Habaek and Mura warns Soah not to trust Tae-eul-jin-in so readily. It is revealed that he is the one who taught Nakbin how to put the curse on Habaek and only the person who placed the curse may be the one to lift it. Thus every year, a bride is sacrificed so that the reincarnated Nakbin would be able to return to the water country and lift the curse. Habaek knows that if he demands this sacrifices from humans, he will be thought of as an evil god and be hated by the people. Nevertheless, Habaek is willing to bear the condemnation in order to see Nakbin again. To make sure that only brides who are Nakbin will enter the water kingdom, Tae-eul-jin-in has erected a barrier that so that any brides who are not Nakbin will not be able to enter but perish in the waves. This causes Soah to wonder how is it that she was able to enter the Water Country, despite the fact she is not Nakbin's reincarnation. (Source: Wikipedia)
A girl from a small village chosen as the sacrifice to please the Water God, Habaek. When she was a child, she was prophesized to love two men in her life. She finds herself attracted to Mui, who she believes is Habaek's cousin, unaware that Habaek (the child) and Mui are the same person. However, later on Soah realizes this, and this knowledge is believed to have been passed on to her by the Emperor. Soah refers to herself as a false bride; eventually it is revealed that her father sold her to take the place of another girl intended for sacrifice.
The God of Fire. He loves everything that is cute. He once stole a peach from Suh-wangmo's garden 400 years ago. In the Emperor's war against Shin Nong, Ju-dong had hoped to be on the opposite side of Habaek in order to learn if he was stronger than Habaek. In the present, he appears to be allied with Habaek and also Bi Ryeom; with the latter, Ju-dong makes an attempt to escape the Emperor's palace with Habaek, but the gods are forced to leave with only Soah.
The Lord King of the East and the God of Birth and Spring. He is Habaek's father, as well as Shin Nong's closest and dearest friend. Because of his own affinity to fire and his decision to ally with Shin Nong, he has separated from his wife and child, and Habaek has long since believed his father has died. Despite his strong resemblance to Habaek, his temperament is entirely different - Dong Wang Kong is gentle and lax-mannered and has had few encounters with humans. (Source: Wikipedia)
