I just finished this drama: Don't Call It Mystery
It wasn't quite as thrilling as I hoped it would be, but compared to most dramas of this genre, it was pretty good. The cases were interesting enough, and the characters were decently-written and decently-acted. The ML is incredibly intelligent, observant, and he talk a lot. Most of the mysteries were solved through the dialogue. Not very many arguments though, as the ML is often right and most characters don't feel the need to refute his statements.
