3. Strong Woman
I only watched (or am watching) a few 2017 dramas. Woman of Dignity is my #1 favourite currently :D Missing 9 was great (during the island arc) but the ending was weird. Reunited Worlds is pretty interesting for me too even though I've only watched 6 eps

"Hit the Top" would have been one of my top dramas this year if it wasn't because of how the ending ruined it for me. I didn't like how it suddenly turned into a rom-com. Before it started airing, the description was something along the lines of: "Father goes into the future to help his son achieve his dream of becoming a singer/idol". So, having them change the last part of the plot to please the audience kind of ruined the idea I had had in my head from the very beginning.
1. Stranger
2. Circle
3. Defendant
