Heir to Jeguk Group. He is the son of his father's mistress, but is listed in the family registry as the son of the second wife in order to be a legitimate child. Though hot-headed and at times immature, Kim Tan is warm-hearted and honest. Although he is engaged to Yoo Rachel, he is attracted to Cha Eun Sang at first sight and falls in love with her despite her poor background.
