I watched the 2016 drama series before watching this drama. I think this drama is meant to be an introduction to the 7th Section aka Higanbana. The concept of an all-female police unit that's designed to protect female criminals and female victims is good, but somehow the plot falls short in some ways. The idea of having the main character with sixth sense is fascinating, but it doesn't deliver well, which makes the whole storyline less impactful. Overall, it's not bad, but it's not very good either.

If I may suggest, watch the 2016 series first and then give this drama a shot if you like.
