The story started with a big 'who done it' type of plot where every single person on the screen was a suspect. It kept this momentum for a few episodes before abandoning the idea and the 'masks' plot half way through to shift to something else. There was no coherency in this mess and the writer was improvising the story as the episodes went on. Instead of working on the mystery, it took the lazy way at every corner, it pushed most of the weight onto just showing the incident. It revealed the mystery through the brief snippets of the incident at the beginning of every episode. The character Kang Hoo was in particular problematic to the narrative and was handled poorly throughout. The cast was good but that's it, and the supposed sismance came off as forced more often than not, even during its high moments. The entire drama was a really big mess.
