I have to admit that for a first few episodes I was not very enjoying the story. It was just plain for me and I just enjoyed the spectacular visuals - the work with colors in this drama should really get some award! Really great...
In the middle of the series I noticed I am starting to enjoy all the characters and their stories and at the end... Especially with the final speech... I was just amazed and couldn't stop my tears... It was fantastic...
So if you are bored at the beginning, don't stop watching this series, because you will be rewarded later.
I suggest to watch this if you like great visuals and stories about strong women in this mad world dominated by social media.
