I was skeptical about the hype around this drama, but a few minutes into the first episode and I was hooked! Binge-watched the whole drama because it was superb. From the intensity and realistic portrayal of the characters by the whole cast, to the storyline that was filled with twists and turns but never once boring, this drama certainly deserved every single acclaim that it received. Recommend this as a must-watch to everyone, except for those who might not be able to handle that reality as adults is very much like the drama.
