I love this k-drama and it deserves a 5 star. It totally captures the thrill inside every episode and I like how it flows thoroughly that there are scenes that you don't expect to happen and every little detail of it makes it very special. And talk about plot twists, this drama is so much more than you think it is. Kudos to the directors, producers, writers, staff and especially the actors. This k-drama will definitely be on my top list.
