WHOA This is the perfect suspense drama according to me and my brother.. It is PERFECT.. In fact it is BEYOND PERFECT.. Everything about this show is beyond perfection.. The creators sure know how to create suspense and MAINTAIN it.. It is such an enjoyable watch filled with suspense but still you will feel satisfied after watching EVERY single episode.. THAT'S how good this is.. You MUST watch it right away without worrying that you might not be able to wait for the next episode because you will be able to wait.. Your mind will be filled with so many questions and theories and you will be discussing every episode and every character the whole week with everyone around you and on MDL until the next week comes with a new episode so you wouldn't even feel like a week has passed.. I am so glad that I listened to my brother and started watching it.. And you should too <3 you will enjoy it as much and even more.. The music is top class, the cast, their acting, the story everything about this show is top class really.. I find myself replaying certain scenes not just because how important those scenes were but also because of how great the background score was during that scene hehehee.. I have watched till episode 7 and by far, this has been my favorite episode.. It's very well made.. Exactly how it should have been.. A round of applause for everyone associated with this show.. Thank you for making this show and making it available for us to watch :) Another great drama from South Korea :) A MUST-WATCH
