the biggest flaw of this drama is the acting of the main actress playing Yoo min Jae. I really had a hard time getting into it and feeling any empathy or friendship for her. Fortunately, the other characters are there to make you want to continue the story. Overall, it's a good drama that can be watched in chill mode and enjoyed. Overall I had a good time. I also have the impression that the beginning of the drama is very long to set up and that the end is closed very quickly. too bad, we don't have all the answers we would like to have and characters therefore go from useful to useless.
