Arthdal Chronicles obtained decent viewership ratings and “buzz score” last week amid Song Joong-ki‘s recent announcement about his divorce from Song Hye-kyo.

Now on its sixth week, Arthdal Chronicles is a historical fantasy drama that depicts the lives of ancient people in a land called Arth as they vie for power and protect their loved ones from enemies. Song Joong-ki is starring in the series alongside Kim Ji-won, Jang Dong-gun, and Kim Ok-bin.

Song Joong-ki announced last week that he has taken legal steps for his separation from his wife and actress Song Hye-kyo, who was also his leading lady in the hit 2016 romantic melodrama Descendants of the Sun.

Industry watchers wanted to see if the the recent divorce announcement would have a negative impact on the ratings of the drama but the numbers remained relatively stable and strong.

According to Nielsen Korea, Arthdal Chronicles recorded 5.8 percent (rounded off) for its episode 9 that was broadcast on Saturday and 6.8 percent for episode 10 that was aired on Sunday. Its TV ratings barely changed relative to its previous records—5.8 and 6.5 percent for episodes 7 and 8, respectively.

Arthdal Chronicles‘ TV ratings have stayed between 5.5 and 7.5 percent in the last three weeks but hit a record low on its ninth episode.

However, when the more accurate audience share figures are considered, Arthdal Chronicles‘ rating actually dropped on Saturday to a record low of 5.767 percent. This figure is slightly smaller than the 5.787 percent recorded by the drama on June 15.

The average rating of the series now stands at 6.6 percent.

Meanwhile, Arthdal Chronicle‘s “buzz score” is still the highest number among all the dramas that were ranked last week by Good Data Corporation. The series owned 17.40 percent of the total buzz, becoming the most buzzworthy or talked about Korean drama from June 24 to 30 and enjoying its no. 1 ranking for the fifth consecutive week.

Arthdal Chronicle‘s buzz scores have continued to drop since its third week despite topping the ranking of the most talked about (buzzworthy) Korean dramas for five weeks in a row.

Similarly, despite the relatively strong and steady performance of the series in “buzzworthy” terms, its buzz score hit a record low last week—falling from the 19.55 percent that was recorded by the drama a week before.

Buzz and TV ratings are two different measures of a drama’s performance with respect to its audience. While the former indicates how many times a series is discussed and mentioned online by the local fans, the latter reflects the number of households that have watched the original broadcast of the series on TV.
