This is my absolute favorite K-drama. The writing is top-notch, the story is grown-up and compelling, and the performances are superb. It was refreshing to see a drama about complex, multi-dimensional women tackling very real professional and personal challenges in believable ways. There is romance, but it's handled more believably than in most dramas. (I particularly like how the writers represented the challenges that attend significant age differences and and a couple having divergent needs and expectations; and I liked that all the central couples approached their partners' needs and expectations with respect and understanding.) But while romance forms a big part of the story, the larger story is about women navigating a difficult world where every decision comes at a cost and where the hurdles don't end. It felt relatable and empowering without ever feeling didactic or like a "lesson of the day"--it was good story that, like all good stories, also managed to cut deep.
