Ever since I watched this drama I've been in a kdrama slump. The same thing happened a year ago when I watched Sky Castle and thought nothing would compare to that. But this drama, it is the highest rated for a reason. Waiting for a new episode to come out was akin to torture and every moment was suspenseful, every character complex, every plot and move gave me high blood pressure. Okay, I realise that's a turn-off for some people, but this drama really does the best work to keep you on edge and I love it for that.
