It is absolutely perfect. Love this drama. This is on my must-watch list. The story is fantastic, background music is amazing, and there is no need to talk about their acting skills. At first, when I biased the main actress in the poster, but after watching this show, my admiration for the main actor is bigger. So devoted and respecful. I also appreciate other supporting role, they play an important part in this drama. This show deserves 10 point average. The plot twist hacked my brain, totally indulged in this drama. I heard there will be season 2, I'm so excited. Hope to see it soon. Can't wait!!!
