It's not really 2 seasons, there was just 3 weeks broadcasting delay in the middle because of Olympics. Otherwise, it's a full 16 episodes drama. However, it would have been really nice if they kept it to 8 episodes because the smaller side cases were really boring despite their relation to the bigger one. Both main characters Dong Joo & Hye Young had a good characterization but the remainder of the cast couldn't carry their own weight and ended up being bland. Although the plot was centered around tracing money but more often than not it deviated away from the tax evasion plot trying to be a different type of show. While the ending may have been acceptable but it left much to be desired. A drama with an interesting concept but it couldn't pull through to the end.
