This drama had such a good start! I was immediately hooked within the first few minutes. The intrigue of the what exactly was going on at the welfare center, who all the kids were, and what had happened to them had me thinking about this drama for days. I looked forward to the weekend so that I could watch the new episodes and then discuss possible killers with my sister. It was so much fun and I was excited to see how the story played out. However. About midway through the drama, when things started to be revealed, I started to get frustrated with the writing. What I mean is that the writers seemed to treat the audience like we're dumb and continuously tried to trick us. They would HEAVILY imply that certain characters were the killer and then in the next few episodes be like, just kidding! It's actually this other person (who would proceed to act incredibly suspicious). I can't stand when shows do that. It feels like lazy writing. Instead of doing proper foreshadowing they spend all their time writing twists into the plot just to confuse/trick the audience. I really did like the first part of the drama and I enjoyed watching all the actors, but overall I was just disappointed by how the story played out.
