I don't know how to write a preview without being spoiler :) so i wil try to make it short. The leads here are not typical at all , so if you are looking for cool arrogant male lead or cute naive girl , you won't get it .both lead have a weekness points in their personality have to be recognized and fixed.the silence play a role in the drama was impressive , the superpower and the blades were metaphor and choice the lead has to make I find the story simple ,but indirect The direction , cinmatography and the music were awesome Lee dong wook was perfect and his expression was wow SSK was cute but sometimes i get annoyed by her stare gaze esp.her character needed more expression Kim kap so was perfect too The flaws, it has a slight slow pace , the supporting characters were needed to be more contributed . the first episode was over the top .over used of flash backs at the first .enjoy it ,thanks
