It's the best drama I've ever seen in my life. I'm that person who loves thriller, mystery and actions. There are so many thriller drama in Korea, Thailand, Japan, China but they all include romance. I don't know how others feel romance in thriller drama, but this is very disturbing to seeing cute romantic scenes in Mysterious drama. I have seen some reviews saying that it's childish to not having romantic scenes, but trust me, THRILLER ONLY LOOKS GOOD IN THRILLER! The fight scenes were for dumb reasons but I found it amazing. It needs more seasons
