Why an 8 for the Story and only a 5 for Overall? An 8 to give the manga's author credit for an original idea and a 5 because the Delivery of a satisfying ending = nada = zip! This drama started out with so much promise … Full Steam Ahead! First 7-8 eps were fast-paced and it seemed as if not only the Who but also the Why questions would be answered by end of show. About 15 minutes into Ep 9, I picked up my iPad and started to play games as I watched. Before too long, the viewers could guess the Who and so most, if not all, of us continued to watch for the Why. Then … The Cute element in the Leads' romance no longer interested me … the Comic antics of the Investigative Team also got boring … If, IF, the writer(s) had thrown out a hint or two here and there as to the Why, I might have continued to actually watch this. Instead, halfway through Ep 13, I went to a website to read the Recaps, hoping to find out the answers to the Why. I didn't … because the answers were just not there.
