You will not regret watching. This is the best kdrama I've watched all year, and it's one of my favorite kdramas of all time. I spam watched every episode. It's high quality. Every episode feels like a movie. The actors are good, so the story is portrayed well. Jo Insung and Han Hyojoo are already some of the best out there, and I love their other works. I want to see the other actors/actresses in other dramas too (especially the young actors/actress).

The scriptwriter well thought out the story. From beginning to end, I was NEVER disappointed. Each episode kept me interested. The symbolism, the romance, the super powers, the everything. I could rave on and on about this. I'm obsessed.
You know one of those dramas that you'll think about for a long time? This is one of those.

I want a second season. Kdrama gods, please.
