Someone made a review saying it was horrible because of the acts, but not the acting, that person give a poor vote of 5 mainly because he/she couldn't take the acts since it's really full of parental guidance.... This kind of rating is quite unfair... If this is not the kind of show you want to watch because of its violence, you have no right to make a review. Your review will be so bias! And take note, this is a thriller type of tv series. Not your usual romcom genre.... This is a deep drama. Violence is expected!
Anyway, this series is worth watching! But, warning, it does have a lot of parental guidance acts, but surely, the story, and the acting of the actors is really convincing! It's a must watch! It is superb and excellent. The actors especially the leading actors were magnificent. This show deserves a high rating! Deserves a high recognition. Brilliantly made! Not your kind of predictable K-drama!
