For the firm's latest brand reputation research that covers the period of Sept. 13 until Oct. 14, the Korean Business Research Institute identified Park as its top celebrity, followed by "Jealousy Incarnate" actor Jo Jung Suk at second place and Park's co-star Kim at third place. The said research findings, acquired by the Korean news outlet My Daily, also included the two "Scarlet Heart Ryeo" stars Lee Joon Gi and IU in its top five list.

A source from the said research institute told the same publication that Park and Kim both reached their respective spots in the brand reputation chart given the popularity of the KBS historical drama. The actor portrays the role of the crown prince Yeong in the said series while Kim plays Ra On, a young woman pretending to be an eunuch.

"Moonlight Drawn by Clouds" also enjoyed steady TV ratings with its highest viewership share at more than 21 percent. With its strong viewership ratings, the drama's cast is expected to schedule a special fan event to fulfill a ratings promise that Park previously made.

The actor along with drama's four lead stars are expected to sign autographs while wearing a hanbok, South Korea's traditional attire. A representative from the KBS drama told local reporters that they initially scheduled the said event on Oct. 19, Wednesday, according to All Kpop. However, the date has yet to be confirmed and may change depending on the cast members' availability.

"Moonlight Drawn by Clouds" will air its final two episodes on Oct. 17 and Oct. 18 on KBS. Watch the preview of the show's penultimate episode below:
