This drama is really intriguing. It has a (quiet) complicated storyline, but it is really interesting to be followed. The storyline is like a magnet to me. Each episode reveal truth one by one, making me excited to watch them. This drama has strong and consistent pace from the beginning until the ending, even some slow paced moments appear. There isn't too much plot holes which make me enjoy the drama more.
The acting of each casts are fabulous, they nailed each character perfectly. To be honest, i have no complain about the acting.
The romance in the drama is really good and they put it with an exactly good amount, it is not too much or less. Many dramas fail to impress me because when the romance appear, the story and circumstances will go astray from the origin line, but it doesn't happen to this drama. I love how the writer keep the story on the track while putting romance in it. The music is quiet okay though it doesn't please my ears that much.

This drama may have an open ending, but if you watch it carefully, there are facts which lead to the ending.

Happy watching
