Im looking for dramas, where there´s a female lead who is in love with her best/good friend. The guy should be not interested or taken or in love with another girl.
Currently airing drama Strong Woman Do Bong Soon --> So far I like it, it's funny. The main lead has crush with her friend since high school but he already has gf.
Also Plus Nine Boys --> There are 3 couple-stories here, but one of them fits your wants, I think (if I remember it correctly),, but this is really a good drama in my opinion :)
