Story I thought from the beginning that this kind of genre would probably get boring, predictable, cliche after 10 eps, but I WAS WRONG. All the mystery and plot are profoundly written. Should I call it systematically? orderly? perfectly arranged? hmm... I enjoyed every single minutes while watching this as it made me intrigued and I often grinned like crazy. :) Fortunately I watched this after this almost finished airing or else I would have need to miserably wait for a week. lol.. This drama started really good, then developed really really great. This one is so underrated.... probably not some people's cup of tea. Acting/Cast Both leads are definitely skilled and talented actor/actress. I like every casts here. They portrayed their characters pretty well. I dont know how to judge if its good or not, but they just are my favor. :) Music I did not have any interest in this drama's ost.. Not catchy on my ears at all.. just good for adjustin' this drama's background music so it feels more alive. Rewatch Value I am not a typical one who like to rewatch but i would rewatch this later sometime in the future. I will just reminisce of some scene ;) Overall This drama is unique, great, captivating, and one of my best favorite supernatural drama :) I am longing for this kind of series. 10/10
