IU and Byun Woo-seok Top Buzz Rankings Ahead of '21st Century Grand Duchess' Premiere

'21st Century Grand Duchess' starring IU and Byun Woo-seok has already captured attention, ranking first and second in buzz rankings even before its premiere.

MBC's new Friday-Saturday drama '21st Century Grand Duchess' is set in a 21st-century constitutional monarchy in South Korea. It tells the story of a wealthy woman frustrated by her commoner status and a prince who is saddened by his inability to inherit the throne. The drama, which premieres on the 10th, promises to captivate viewers with its unique world-building and intriguing plot.

The drama stars the multi-talented IU (as Seong Hee-joo) and the ever-popular Byun Woo-seok (as Lee An-daegun), drawing significant interest. Joining them are actors Noh Sang-hyun (as Min Jung-woo), Gong Seung-yeon (as Yoon Yi-rang), Yoo Soo-bin (as Choi Hyun), and Lee Yeon (as Do Hye-jung), creating a perfect synergy that appeals to viewers' tastes. Notably, IU and Byun Woo-seok achieved the top two spots in the FUNdex TV-OTT drama buzz rankings for the first week of April 2026, as announced by Good Data Corporation, proving their popularity.

Additionally, the drama's script, which won the 2022 MBC Drama Script Contest, has been recognized for its entertainment value. Directed by Park Joon-hwa, known for his trendy visuals in 'Alchemy of Souls' and 'What's Wrong with Secretary Kim,' the drama raises expectations. The combination of a trusted director, talented actors, and a fresh storyline makes '21st Century Grand Duchess' a highly anticipated premiere.

Set in a 21st-century constitutional monarchy, the drama follows Seong Hee-joo (played by IU), a successful businesswoman who struggles with her commoner status. In contrast, Lee An-daegun (played by Byun Woo-seok) is of noble birth but cannot become king due to his fate. To change their destinies, they enter into a contract marriage.

The drama also highlights various relationships that enrich its world. Prime Minister Min Jung-woo (played by Noh Sang-hyun) is a close friend of both Seong Hee-joo and Lee An-daegun, but their contract marriage begins to shake his loyalty. Meanwhile, Yoon Yi-rang (played by Gong Seung-yeon), who must protect her young son and the royal family, adds tension by opposing Lee An-daegun.

The drama promises to be a 'relationship hotspot' with Seong Hee-joo and her chief secretary Do Hye-jung (played by Lee Yeon) aiming high, and the loyal bond between Lee An-daegun and his aide Choi Hyun (played by Yoo Soo-bin). With fierce competition, warm support, and friendships stronger than blood, '21st Century Grand Duchess' is set to offer a variety of entertainment.

'21st Century Grand Duchess' premieres on the 10th at 9:40 PM.
