This one is a masterpiece legit. Considering how braod the plot is the drama is very well written. There is not a single loophole in the drama. NOT EVEN A SINGLE ONE. It's not a average psycho thriller💯 it's really something out of the box, so if you want to experience something really good then this is it. Even though the episodes might feel a little draggy but they never fell short on the thrill side, it was always engaging. The plot twists are unpredictable and the actors slayed it. It's a whole package. But if you're not someone who can't handle complex plots, please slip mouse, it is not everyone's cup of tea, all inclusive one of the best k-dramas
