Han Se-kyung is a young woman with a very positive character. Her motto is "effort will take me as far as I want to go". She wins many designing contests and finally joins a clothing company. But, at work, Se-kyung does errands and chores rather than design. Meanwhile, the wife of an upper management employment at the clothing company humiliates Se-kyung. The wife is actually a former high school classmate of Se-kyung who didn't do better than her in school. This makes Se-kyung look back on her life.
