She is an attractive young woman who is daughter of a rich man. She pretends to be Han-Ah's friend, but in truth she envies her and doesn't want her to be happy. It's been told that she is the daughter of a mistress. Also, she used to date Mi-Yoo before moving, but she broke up with him because he suffocated her. She tries a lot of different and persistent methods to break up Han-Ah and Yoo-Min, but all her extra efforts were in vain. She decides to use Mi-Yoo, and it results in Mi Yoo catching Han-Ah together. After they separate, she no longer talks to Mi-Yoo, and he becomes aware that she was only using him. He tells her that she can't date Yoo-Min. She ignores him and goes to visit Yoo-Min at the hospital. Then Mi-Yoo calls her telling her to forgive him for what he is going to do. She discovers, later by a phone call, that he kidnapped Han-Ah, and he tells her that Han-Ah is the only one she has opened her heart to. She realizes is true. After Yoo-Min saves Han-Ah, she visits Mi-Yoo at the hospital, and he tells her that she hasn't changed. She is still the same spoiled, lonely girl from kindergarten. She meets Han-Ah outside and Han-Ah hugs her. Then she tells her that she was envious of her happiness and of her scent. Han-Ah tells her the secret Mi-Yoo told her while the kidnapping : "Let me tell you something about your future, You'll... be happy". From Wikipedia

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)
