I will note that part of what makes this drama boring is that for where I live, only one episode per day airs separated by a week...if it were really an engaging story I'd stick with it and not mind the wait for a next episode but when I realized I couldn't be bothered to do so, I had to admit that while it's cool to have nearly the same cast (I love the leads from their other works) , there is nothing to the story to hold your attention to want to see what happens next, and actually there is a heck of alot of inactive dialogue scenes that I suppose moves the story forward but you say to yourself, 'huh, so what?"
That said, Mysterious Lotus Casebook airing at this same time is super dialogue-detective analysis heavy but it works for its plotline and the mischevious acting of the leads. So, I can't recommend this second season unless you are such a diehard fan of season 1.
