Not many dramas has this kind of factor, especially a k-drama. It's very unique and you can't hate any main characters because the writers delivered their stories effectively. I would say that it has realistic ending and would recommend this anyone who is struggling to find a purpose. It helped me see a different point-of-view and I think Kim Tae Hee really brought out her A game to her comeback drama. If you're not into korean drama, I think you can ease your way by watching this.
