At the beginning I started to follow the young girl as she reads the diary of her mother. I started to enjoy the story as it went a long. The 2 young leading ladies, I love they were young but smart and competitive. One is doing it for her family and one is doing it for herself. As the male leads get added to these girls life the story becomes more complex and interesting. The actors performance was great and you really could feel the story as the young girl reads from her mother diary in every episode. But then the end happens. You are left hanging (what happen in the present time !, their future !, now !) If they were going to tells us the story of these characters when they where young why not keep the whole thing as they were young in the past until they got to 25/21. Why did they keep bringing us to the present time. They only showed us a 2 characters of how they are now and talk about some of the characters but gave us no glimpse of what happen to them now and then nothing. We are kept with just the memory of the past but not the present. We only know about the FL and her mother but not everyone else. I kept wanting to know did the present FL and ML ever meet again as they are older. What happen with the other FL, did she get married. My heart broke. DISAPPOINTMENT.
