What series is this? What an electrifying plot! A very well-tuned cast and a surprising performance by the beautiful Han So Hee, The same goes for actor Ahn Bo Hyun, who is very good as detective Jeon Pil-do, Very good indeed! The story is surprising and very well tied together. The acting and interaction of the entire cast and the story itself captivated me from the first chapter and I couldn't stop watching until I reached the 8th and final chapter. I couldn't resist. I ran a marathon without fear of being happy. The series is agile. Congratulations to the entire team for this brilliant work!
