This is a very good drama with a mix of action, revenge, and a very good romance. I would not consider this drama a sequel because, although it has the same leading couple, it is a different story. It is not a continuation of the Mysterious Love plot and it is neither a sub plot nor a story of a character that comes from the drama Mysterious Love. The storyline of twin flowers is not unique but it is well presented and played well on this drama. The drama is not perfect but the cast did a great job bringing their characters to life and the leading couple has a fantastic chemistry. Enjoy it!
