A great story that doesn't make you feel like its being dragged out, like a lot of 40 episode Chines dramas do. It has a little bit of light heartedness sprinkled over a serious setting but well balanced you might even find a few laughs. There isn't a single time when you think to yourself "when is this going to be over" . Also ep. 40.5 which is 5 minutes long but will put a smile on your face.
