I was introduced to iQiyi's Light On series through The Bad Kids, which is until now, one of the best drama that I've watched. This is the second Light On Series that I've watched. Although it is not as good as The Bad Kids, but it is a pretty good mystery drama that keeps you at the edge of your seat. The story is told really well in 12 episodes, which makes the pace of this drama just right. The end of each episode ends with another piece of the torn photograph that will contain the clue to the mystery and every episode almost always ends in a cliffhanger and will leave you hanging if you don't click that next episode button. I was hooked from the first episode until the last one The acting is also top notch from the main and supporting characters. Special applause goes to Bai Yu who portrays the Jiang Yang character, who is the main character and the central of the whole drama once you've watched the whole drama. If you like mystery dramas, I would definitely recommend you check this drama out with advance warning: the drama deals with dark and difficult issue which can be sad and depressing for some.
