Ham Eunjung is the local, best detective and is also known as “The Decisive.” There is a serial killer among the city, and she is struggling to solve the case.  Park Hyomin The heiress of a famous, successful fashion, photography, designing, and modeling company. She is smart, business-savvy, and is kind and considerate to everyone, including the poor. Her family is very strict, however, and they do not associate with commoners. She’s got the looks and everything, what more could she need? She meets someone in her life -- another girl -- which strikes her in awe, but what she doesn’t know is the girl’s true nature and her deep secret of who/what she truly is. Park Jiyeon She gives out the usual, typical commoner appearance. She doesn’t really care for what people think of her, and she does her own business. With an IQ of 180, she has the talent of being able to manipulate people and use them to her own advantage. She has a scarred past and a dark secret that no one knows about, (or has forgotten), and she has a specific, strong disliking for wealthy people. She uses her job as an advantage for her ulterior motives. Her mind is so mentally unstable that she can turn bipolar all of a sudden any minute.  Ham Eunjung A middle-class girl who gets close to Hyomin because of her job, and is attracted to her. They begin as strangers to close friends, but Eunjung tries to get closer to Hyomin -- a little more than close friends -- while Hyomin does not notice it as she is too busy with work. She notices Jiyeon who has become a friend of Hyomin’s, but she suspects something of her. She just… Can’t quite crack the code on Jiyeon and becomes a bit more alert and suspicious.
