I really enjoyed this drama! It was engaging with an interesting story and good characters. I liked the mystery a lot and thought they did a good job of giving us lots of twists without getting out of control with them. However, while I do think 12 episodes is the sweet spot for most dramas, this one felt like it rushed everything in the last episode. There were a few things that I would've liked to have had answered (mostly what actually happened to some of the major characters that were either about to die, apparently terminally ill, or in jail). But I definitely enjoyed it from start to finish and would recommend it.
