Very great cinematography, well-built intro, the actings from all the actors & actresses are exeptional. I'm drawn to this series because of all those things.
However, like other Kdramas, the script & storyline are exaggerated & irrational in some details and making me lost interest in watching it at some points. The 2 first episodes are decent but it get worse after.
The main problems which lead to vengeance & conflict can be solved by telling the truth about whose child Mo-mi is. In overall, this is an "ok" series to watch in spare times. 7 out of 10.
