Korean Drama Ratings: Highlights

1. What’s Wrong With Secretary Kim breaks records in viewership. Man, this show’s ratings are going nowhere but up. The drama premiered with a record-breaking pilot episode rating of 5.757 percent, the highest among the pilot episode ratings of cable dramas so far this year. It then surpassed 6 percent on its third episode and has achieved 7.687 percent for its latest broadcast. The result? An average rating of 6.505 percent, making it the highest-rated Korean cable dramas so far in 2018.

2. Lawless Lawyer surpassed 7 %. As this series nears its finale, it has achieved an all-time high rating of 7.089 percent, making it one of the only few cable dramas so far in 2018 to surpass the 7 % percent mark. This is a remarkable achievement for the drama whose average rating of 5.9 percent already made it to the list of the top Korean dramas in the first half of 2018.

3. Are You Human Too? nearly reach double-digit viewership. This is all thanks to the cancellation of its rival shows’ broadcast on June 12 (due to coverage of local elections). The sci-fi romance drama achieved 9.9 percent in nationwide viewership, its highest rating so far since its premiere.

4. Life on Mars renews peak rating to almost 4 %. The Korean remake of the British series of the same title is doing all right as far as TV ratings are concerned. It premiered with just 2 percent and now has basically doubled this number for its latest episode which got 3.969 percent. It already beat Sketch on the weekly ranking of Korean dramas based on average ratings.

5. About Time hit an all-time low rating below 1 %. This show is definitely having a hard time wooing the viewers as the broadcast on June 18 recorded a very disappointing 0.887 percent. The series’s ratings are actually hovering around 1.5 percent, so the drastic drop in ratings is quite sudden—something that can be blamed to the FIFA World Cup match between South Korea and Sweden on that very day.


Me? Just an ordinary lad with an extraordinary (says this something called 'stereotype') habit of watching Korean dramas. It started with action-filled City Hunter and the rest, as they say, is history.
