A very, very, VERY slow burn. Far too much build up with zero to little satisfaction, twists or reveals at the end. All this scheming and literally for no pay-off in the end. They keep talking about revenge, but there were almost no consequences to any of the actors in the show, their lives all continued as normal. Where's all this revenge I kept hearing about? I was interested in seeing how this tortured teen would exact her revenge, but it all lead to a bland cliffhanger.
I feel like I wasted my time watching this show. I don't watch K-dramas often, and I will continue this trend after watching this.
