I really liked this drama because it was different from the others I watched before. It does not deal with a love story as the main story, but centers on the relationship of the two girls. I really liked, the (in fact very implausible, but that can't be a measurement in dramas xD) story and the conflicts it caused. I also really liked the characters changing. In the beginning I really didn't like Seo Jung Eun, but that changed. I also liked the "bad", the supporting cast. And I liked that there were no real "bad ones" or only "good ones". I also really like the supporting cast of Seo Jun Euns friend and Lee Youngjos Brother. It was refreshing and funny. I would have liked more about that ;) Of course, there were things I didn't like also. The lovestory of the mainleads could have been so much more wonderful! But they didn't really got the chemistry maybe. In ways of Seo Jung Eun I think her character could have been more interesting if she had a darker tone also, I mean if she would not always do everything "right", but that's my opinion. Also Lee Young Jo was a little colorless as a character. Then I would have liked Seo Jung Eun to visit her adoptive home of her childhood once again in the later episodes and also have more like a REAL friendship with Mi Ryun, because Mi Ryun couldn't even tell her she can't have babies? Why not talk about that as friends. And I didn't like Han Yoo Kyungs clothes. She looked like 13 with that small figure of hers, like a doll.She always had very short skirts. I wouldn't have taken her seriously as a producer. And I mean, she wanted to be tough, to look tough. But still look supercute? Maybe for the manly audience. And that Han Byul was always shoutin Daddy! was a little annoyin to me too. I still really enjoyed watching. I didn't really notice the music. Nothing to listen to later for me in it, but not annoying either. There are only very little dramas I would watch twice, because I think it's boring if you still now what was going on. No actor of this drama blew my mind that hard that I'll have to watch this again, even if Joo Sang Wook is eyecandy, indeeeed. I think the story didn't get boring, but "the suffering" in the later episodes was tiring. I would recommend this drama! It makes you think on your view of things :) So, that's it, my very subjective opinion.
