I have a mixed feeling with this drama. Even though the female lead can be stupid sometimes, even despicable and totally obsess with her works, I like the male lead and all the side characters. Each case brings me a beautiful story and meaningful growth for each character. However, one of the flaws of the drama is that you are being made to wonder with will they or won't they get together. Both male lead and female lead are ex's in the past but you can still find that they still have some feelings left and their attraction shown in an indirect way.  The ending is justifiable and realistic with an open interpretation.
