Worth your time !

this drama is about friendship and women’s life in thirty, how they face life problems, and fall in love. I like the concept and the story a lot, but this drama has two negative points, the open ending, and the long dialogue, at the first part I enjoyed the dialogue and liked it a lot, but in the last 10 episodes, I felt it was boring and wished it was shorter.
I fell in love with this drama and all the actors and characters but why did they end it this way? I want to know what happened to YuTian and Karen, I deserve it :(
