The Acting was pretty good but although i think maybe with stabbing scenes the acting was a bit low. It might be because they didn't wanna involve much on the violence. However i have only watched 1 episode and I'm glad to say i will definitely watch it when all the episode are out. I really love the acting of the male lead but i would of liked a little bit more psycho acting. But overall i do think these acting have definitely mastered the show its very interesting. I really love plot on the first episode but however i think is it bit rushed. But i do suggest to wath it. The music was okay but i didn't take much notice the music.
