all I can say is, WOW. I didn't imagine it to be this good. this drama is way, way underrated, yet a very good series to binge. 8.5/10 for me. it was worth my time.
I would urge people who haven't watched it to put every other KDRAMA on hold and watch this. Don't mind the negative reviews. This drama is one of the best thrillers I have watched. The plot twists were CRAZY. Even though I had browsed for spoilers and watching videos to get a sense of where I was going, I still didn't see these twists coming. This was a 10 for me and nothing less.
