I saw this drama back around 2009, and I remember it was an older drama even then. It has to be either a ’90s or early 2000s drama. What I remember–there were two sisters, the “good” sister and the “bad” sister. (The bad sister might have been a stepsister, half-sister or a cousin, can’t remember.) The good sister designs shoes. The bad sister, a.k.a. second female lead, either ends up working for the same company or just in the same field, and steals her designs. There is a male lead and romance but I don’t remember specifics. It felt very old, like Tomato or Attic Cat, with the cliched, jealous second female and Candy protagonist. But beyond the age and the stolen shoe designs I don’t remember much else.
