Korean Drama Ratings: Highlights

1. 100 Days My Prince‘s rating skyrockets to 7 percent. This drama is doing it fast, from posting 5 percent during its premiere to recording 7.274 percent on its fourth episode. If this rate continues, it is only a matter of time before the series surpasses 10 percent. Amazing performance!

2. Familiar Wife ends broadcast with over 7 percent. A total of five dramas ended last week, with Familiar Wife being the notable one for posting 7.870 percent during its finale, a figure that manifests a massive success for any cable drama. The series recorded an average rating of 6.820 percent, making it one of the highest-rated cable dramas in the second of 2018 so far.

3. Thirty But Seventeen achieves highest rating during finale. The series recorded a double-digit viewership of 11.0 percent, making the average rating of the series equal to 9.0 percent. It failed to obtain an average rating over 10 percent, but it can be considered an average drama as far as its ratings are concerned. 

4. The Guest records 3 percent. From 1.6 percent in the first episode, the drama now has a rating of 3.207 percent, making a significant progress in wooing more viewers to watch the series. It’s good that OCN is experimenting on a new time slot. Fingers crossed that this drama will receive a decent overall viewership to encourage the network to broadcast more dramas on this timeslot.


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.
