Both are fashion based. If you liked watching Miss Buyer then Sunshine of my life is right up there.
both female leads are hard working and underdogs, strong work ethic , wanting to make a name for themselves in the fashion industries just in different ways etc.

Male leads: Sunshine of My Life....the ML runs a fashion empire, FL comes to inspire and push him
Miss Buyer...….same thing for Sunshine of my life, ML is a designer and the FL is a buyer

In both dramas together they work with each other to push each other and career forward with the occasion hurdle
