Singer and actor IU expressed anticipation for the upcoming work "21st Century Grand Royal Consort." On the 16th, IU posted on their SNS, "April 10, Friday, 9:40 PM. It's fun," along with a drama poster. The poster features the main cast, including IU and Byun Woo-seok.

"21st Century Grand Royal Consort" is a drama set in the 21st-century constitutional monarchy of South Korea. The story revolves around the fate and social status-breaking romance between a female lead who is a chaebol with everything but of commoner status and a male lead who is the king's son but has nothing. IU plays the role of Seong Hee-joo, a character who chooses a contract marriage to overcome the limitations of her commoner status. Byun Woo-seok portrays Lee An Daegun, the king's second son, who lives confronting his own limitations.

The drama is scheduled as an MBC Friday-Saturday drama and will be simultaneously streamed on Disney+. This appears to be a strategy targeting the global market. The released poster depicts the four main characters standing in their respective positions against the backdrop of an antique palace interior.

Seong Hee-joo, played by IU, is the CEO of the beauty company "Castle Beauty" and a prominent figure in the business world. However, she struggles with the limitations of her commoner status. Lee An Daegun, played by Byun Woo-seok, has the dignity of royalty but lacks actual authority. Their announcement of a contract marriage forms the main development of the drama.

Supporting roles include Noh Sang-hyun as the cold-headed prime minister and Gong Seung-yeon, who contrasts with her young son's ascension to the throne, adding weight to the story. "21st Century Grand Royal Consort" is expected to reveal a new side of the Korean royal family through a narrative where status and power intersect.

The drama will premiere on April 10 at 9:40 PM. IU expressed confidence in the work, drawing much anticipation.
