Triple is a whimsical look at a group of people drawn together by one girl's dream of becoming an figure skating champion. After her mother and stepfather are killed in a car crash, talented Lee Haru gives up her pursuit of a figure skating career and goes to live with her father. Five years later, an encounter with an old rival sparks her competitive streak again. Haru decides to move to Seoul to train and stay with her stepbrother, Shin Hwal, whom she hasn't seen in years. Hwal is less than pleased when his long-lost stepsister appears on his doorstep, but his roommates welcome her whole-heartedly. What Haru doesn't plan on is beginning to develop feelings for her gruff stepbrother, and when her new skating coach turns out to be Hwal's ex-wife, all sorts of sparks begin to fly—not just between Hwal and Haru, but between all four living in the house. In this funny, addictive drama, one girl's struggle to make her dream come true changes the lives of everyone around her—starting right at home.
