Wow, I just finished it and my heart is still on speed 200.
I came to the series following the talented actor Jang Ki-Yong, although it has been 6 years since the series came out, and it was followed by other high-quality series at an international level, and it is still a masterpiece, with a perfect casting of the entire cast (from the young to the adults), and the awards she won will also testify to that. No chapter is superfluous, the storyline is maintained with a level of tension. I must point out that the series has very violent and cruel parts, at the same time it also has love, healing and recovery, great chemistry between the actors (not only between the main characters but between parents and children).
The soundtrack is wonderful and fits the plot wonderfully
