Song Joong Ki has weighed in on the popularity of "Moonlight Drawn by Clouds," a KBS drama that features Park Bo Gum. He conveyed his surprise on the said drama's quick rise to fame amidst speculations that it may attain the same level of success as "Descendants of the Sun."

KBS' new historical drama may have started with low ratings but it soon catapulted to fame given its storyline and the great chemistry between its cast members. "Descendants of the Sun" actor Song has shared his thoughts on the strong ratings that "Moonlight Drawn by Clouds" has enjoyed so far. He told reporters at the red carpet event of the Seoul Drama Awards held on Thursday, Sept. 8, that he was happy over the success of his fellow agency actor's drama, Soompi reported.

He stated that he had high hopes for Park's historical series where the said actor portrays a crown prince during the Joseon dynasty. Song also expressed his surprise on the growing success of the KBS drama. The viewership share for the series' second-week episodes has jumped to twice its size as compared to its premiere week.

Ratings for the series' first week were around 8 percent but grew to 16 percent during its second week. It is also close to breaking the 20 percent rating mark, according to Nielsen Korea. Song commented that he had no idea that Park's drama would do so well at such a fast pace. He also thanked the fans for showing their support for the "Reply 1988" star.

On the other hand, Song's "Descendants of the Sun" has been applauded for its massive popularity. The said drama that also aired on KBS in early 2016 has achieved an impressive viewership share of more than 40 percent. It also became one of the most popular Korean dramas that were exported to China, Forbes reported.

At the moment, it is still unclear if Park's drama would be able to enjoy the same success level as Song's "Descendants of the Sun." The KBS historical series has yet to reach the mid-point of its 18-episode run.

"Moonlight Drawn by Clouds" airs every Monday and Tuesday on KBS.

Watch a preview for the drama's episode 7 to be released on Sept. 12.
