A talented and gifted ballet dancer. She is Shin's girlfriend, but rejected his proposal as she did not wish to give up on her dreams of becoming a star ballerina. When she sees Chae-kyeong and Shin's wedding and how much Chae-kyeong is loved by the people (similar to the rapport of Diana, Princess of Wales), she regrets her hasty decision, and does everything to win Shin back, including engineering a "chance" meeting in Thailand. She ends up hurting herself, driving her to attempted suicide by overdosing on pills. She later recognises that Shin does truly love Chae-kyeong, and ultimately concedes and instead decides to concentrate on her career as a ballerina.
