A Fictional Monarchy and Unlikely Romance

The drama '21st Century Grand Princess', which premiered on April 10, 2026, and concluded on May 16, posited a fascinating alternate reality where 21st-century South Korea operates under an imperial system. At its heart was the story of Sung Hee-joo (played by IU), a chaebol heiress blessed with beauty, intellect, and immense wealth, yet perpetually frustrated by her commoner status.

As Sung Hee-joo, IU delivered a performance that significantly departed from her previous roles. Her character, embodying a blend of entitlement and vulnerability, allowed IU to explore new depths of expression. Critics noted her ability to convey complex emotional shifts not through overt gestures, but through subtle facial expressions, the intensity of her gaze, and even nuanced breathing. This refined portrayal heightened the drama's tension and lent persuasive depth to Sung Hee-joo's journey, proving IU's remarkable growth as an actress capable of captivating her audience with quiet intensity.

The Powerhouse Duo: IU & Byun Woo-seok's Synergy

Long before its broadcast, '21st Century Grand Princess' was hailed as one of 2026's most anticipated dramas, largely due to the star power of IU, fresh off 'You Have Done Well', and Byun Woo-seok, who had recently soared to global fame with 'Lovely Runner'. This formidable pairing generated immense buzz, with the drama securing the top spot in TV-OTT drama buzz rankings even before its premiere, as tracked by Good Data Corporation's FUNdex. The show's global appeal further solidified its status, climbing to number 5 on Disney+'s Top 10 TV Shows worldwide, claiming the number 1 spot in the non-English category, and topping charts in 16 countries, including Korea, Japan, and Taiwan.

Navigating Public Reception and Controversies

Initial Mixed Reactions and Growing Acclaim

The drama's early episodes faced a divided audience response. Some viewers found IU's portrayal of Sung Hee-joo to be somewhat "contrived" or "excessive," even drawing comparisons to her character Jang Man-wol from 'Hotel Del Luna'. Similarly, Byun Woo-seok's pronunciation and intonation received some criticism. However, as the series progressed, both actors delved deeper into their characters, the initial criticisms waned, and their on-screen chemistry blossomed. The drama consistently topped TV-OTT drama buzz for three consecutive weeks after its premiere, with IU and Byun Woo-seok dominating the top two spots in actor buzz for four weeks. The finale achieved a peak national rating of 13.8%, marking a successful conclusion and securing the top spot in its time slot.

Addressing Historical Fidelity Concerns

Towards its conclusion, '21st Century Grand Princess' stirred controversy regarding its fictional world-building and historical accuracy. Specific concerns were raised about the drama's depiction of the class system and the use of 'cheonse' (long live the king) during Lee Ahn-daegun's coronation, along with the design of the royal crown, which viewers argued resembled symbols of the Japanese imperial family rather than those of the Joseon dynasty. In response to these criticisms, the production team issued a public apology.
