I was originally upset that they changed the male lead and so I had put off watching the second season for the longest time. I also watched this drama like a year after watching the first season so I wasn't attached to captain Jang whatsoever (mainly because I didn't remember him or season 1). I recommend watching season 1 again if you didn't watch it recently.

I really like the chemistry between Ha Na and Jin Wook. I also love that Jin Wook has such a complex history, which gives his character a lot more depth.

The story flows very nicely and nothing seems like filler. Even the small everyday crimes have a link to the bigger overall plot of the story (which is SO impressive imo). The only negative thing I have to say is that sometimes they make connections between the MOST unlikely events, which seems a tad bit unrealistic, but is super easy to ignore. I also feel like they were a little too stoic when finding out a loved one or a teammate was in danger (although it can be explained by their police training to stay calm I guess?).

Really loved the drama, and it's really impressive that it has not one, not two, but THREE successful seasons when dramas typically will only have one. The plot for each season is super well done and thought out, completely unpredictable and shocking every time. I loved it!
