This drama was heartbreaking. I've been crying for the last couple of episodes because of it. This drama started of really good and really caught my attention. However, episodes 9-18 were not the best. Those episodes had interesting scenes, but it got boring. I'm really giving this show a 9/10 because this isn't some simple drama. It definitely is not for everyone. Episode 20 onwards were magnificent. I fell in love with all the characters; Eugene, Ae shin, Hina, Hui sung, Dong hae and more. I don't see myself watching this series again, because I don't think I can put myself through that sadness again. All actors and actresses were absolutely amazing and I'm really happy to have watched such an amazing show.
