It was overall a great and fun detective drama. Loved the chemistry between the characters and the acting. The plot for each case they solved was really good. But there seemed to be quite a few plot holes or things that were brought up but just left hanging, unexplained, and not followed through. The ending (as in the last 2 minutes) really just made the whole drama feel like a let down because it was such a out of the blue cliffhanger and none of the plot holes were filled. I'd also rant about the relationship between Haruya and Mui but I don't want to give spoilers out for the ending.
