For first 2 episodes, it seemed promising but soon it became a drama touching every bit of the character's role, hence lack of character and story development. They have quite a bit of main characters in this drama and 25 episodes are not enough to develop their story and character well. It is a drama with good looking cast, that's all. I am not sure if this is the normal for HK dramas but I would recommend you to watch without expecting anything in the end. I ended this drama with lots of question marks.
