Finished this drama today. It was nothing special, though I had hopes for it. The starting looked promising. As I reached the middle of it, I was really bored and FL was one of the main cause for it. And she only got worse. ML was okay I guess. He remained constant through out the drama.
By the end, the one character that had me watching it was, Lee Rang (ML's brother). In the beginning, I disliked him. But as the drama progressed, he showed different colours. His character had much more depth and development than anyone else in the story.
