I enjoyed this drama. The story was good and there were some plot twists that literally blow your mind. However, I don't like the ending because I felt at the ending the couple were still hesitating and cautious about each other. I mean it is so obvious that they need each other and that might be their happy ending. Overall, what I really need to say is the ending was ambiguous. I personally think the audience needed a definitive ending because they waited for a better and happy ending for Sang Su and Su Young.
