This drama has everything you would expect out of an action/mystery drama with a basic premise: a brash male lead whose curiosity knows no bounds, his sunbae who is unwittingly dragged into his schemes no matter how hard he tries to get out of them, a maknae who seems like an amateur but is the one who's doing most of the work, or at least most of the work they're actually supposed to be doing.

A female lead who is kind of a badass but becomes kind of childish around the male lead (as does he around her) to depict their contradicting personalities, another sunbae the crew used to work with, and now the male lead dislikes for a reason that is very intricately connected to the plot and of course, a very handsome villain who puts his fists to use first.

We have the storyline of several different cases converging to seemingly become one case, and all signs pointing to our villain being the one behind all this. There are tons of characters and you don't really know what's going on, until you do, and of course, it all culminates in the final few episodes.

So what else? Well, the comedy is pretty good, as is the mystery. The drama being set around the Han river also makes it a pretty new addition to the genre. The pacing is good and for 6 episodes, they tie up the loose ends pretty well. And the crew actually seems to do their jobs (in addition to the crime scenes they inadvertently come across, of course). The small plotholes and few of the conclusions being not so satisfactory aside, this was a fun watch.
