It was good. After episode 4, I couldn't stop watching it. Just like a true thriller I was hooked. It was unfortunate how little the characters were developed. Our Changmi kept the same attitude and approach throughout her search. The planned revenges were nicely done and thought so I was disappointed that all confrontations felt lacking in comparison.

Like many thrillers, the "plot twist" was a bit overused. Every event had its own plot twist. You can hardly see it while watching so I hope if you are seeing this before watching the show it doesn't stop you. In the end, this is a good show and I truly enjoyed it esp the first 10 eps of its run.
