I enjoyed this crime movie. Dark but not too dark, emotional, well made and no cringe. The female lead is perfect for the role she wasn't annoying or anything and Lu Han also did a great job playing the carefree and borderline rude but good at heart guy who loves roller blades. The female lead started as a cop trying to get her brother to quit his friends and they end up getting in an accident that leaves her blind. I also like that for once a movie features something other than romantic love. Actually when the female lead meets lu han he reminds her of her dead brother. And even though at first lu han doesn't appear to be getting along with her but the second she gets in trouble he's there trying to save her.
