Mature and lovable plot. It grabbed all of human emotion. I think dramas nowadays are trying to make the story to be more make sense. Sometimes it became too real and not appealing anymore. But, this one hit either drama or logic at the right spot. The storyline is not a common idea for a tv drama. It keeps you thinking for what will be happen next. This production keep the balance of 'dark' and 'bright' area well. I believe that I have learn something and having a new understanding about human psychological state. The story is fresh and inspiring. There's nothing much to say about the cast. They're selected well and suitable for the roles. It wasn't only because of their big name, they did a great job here. Thumbs up! The ost. were great and I think represent the story right. This drama is a great production, and worth to be watch. Best of the year.
