Though it started somewhat slow-paced, boring if I must say, and with too many background stories, halfway thru the season, it picked-up. The scenes got more interesting and the foreshadows are subtle you'll never notice it upfront. You have to have watched the episodes to be able to understand the scenes otherwise you'll get lost. and don't get me started with all the twists, never had I watched a Korean series with this kind of twists and turns that you won't be able to predict what's next. I literally had goosebumps at the end of episode 8. Kudos to the writers!!! The actors were really good as well. They stand out every time. 10/10
