After watching the complete drama what I felt is, I think the director wants to portray the life of ordinary people and rich peoples but he is failed to convey it properly. To some extent, I liked this drama but the major blunder is the female lead character. She loved three male characters but to everyone, she told the same thing that she loved them very much, the same line everyone she loved without any guilt in the mind. I don't think loving three persons so deeply in ten years is that easy without having any guilty. The main upsetting one whenever she saw her ex's her heart flutters even though she is in a relationship with someone. From this drama what we can learn is, how to take advantage of everyone for our own growth.
Even though her friends betray her so many times she gave chances to reconcile but the one she loved or the one loved her, she didn't give the single chance even though she took so much of help from him.
After watching the complete drama we can say that the character of the female lead is not worthy or suitable for the lead part., because according to my experience very few girls have this type of fickle mentality or character in a deep love perspective.
