I don't think this is a bad drama as what others think. The drama is pretty solid with it's theme and also how it portrayed it's leads. The drama did get boring at the latter parts, since the climax part did not really have that impact that it suppose to give. As I get to the episodes one by one, I came to appreciate the drama and how it unfolds. I also appreciate that they wanted the characters to have a proper ending, almost significant character in the drama is given the spotlight in the end. One downside of the drama for me is the downfall of the excitement or the interest of the drama.
I like the main leads, their acting is great for me as a watcher. The chemistry is also there. I also like the OST. I think this is a pretty decent drama, and I would still recommend this one.
