Wow, this is the definition, to me, of a great drama. I have noticed TvN do amazing dramas. Lately I have been watching a lot of korean dramas that just are so shallow and lacking that I haven't deemed them worthy to review, this definitely pulled me out of that stupor of 'korean dramas have turned to sh!t.' :P It's also been a long time for me since I binge-watched a drama and I just couldn't stop watching this one. The story kept me guessing and was both so heart-wrenching and warm. Towards the end I cried a few times, but I find those dramas that make me cry get me so emotionally involved. The acting was great, obviously with Chun Jung-Myung and Choi Kang-hee was very convincing also. I hadn't really seen much of her acting apart from in Protect the Boss, so it was nice to see her in such a serious (?) role. Honestly you should watch this right now!
