The first 4 episodes was a bang. I just finish the drama yesterday and my thoughts are quite out of place. The drama is packed with well known but amazing actors and actresses in the korean drama world. Seo In Guk is really good, though I can only see his face with death and their conversations. Every episode is a way to present how valuable life is. The most memorable for me is the baby episode, it was not expecting it so I enjoyed it. They put some light moments in the drama, which I like since it is really a dark drama. The ending is a cliffhanger so will see if it will live up to the first parts of the drama.
