Han So Hee did amazingly fantastic job in playing JiWoon character. Ji Woon is strong, fierce and the way she fights is beyond words. You can only admire her for her vengeance and determination. And yes detective Jeon Pildo is there to add some spice. I fell in love with Cha Mu-jin character. He is a very hot villain specially in the beginning when he teaches Yoon Ji Woo to fight. He's the kind of person that you know is pure evil but still you admire him because he is too good at what he do and his obsession with Ji Woon is something that add the spark to his character.
