IU has offered fans a first glimpse of her latest role in the upcoming MBC drama The 21st Century Grand Prince’s Wife, posting a behind-the-scenes photo on Instagram.
On Wednesday, IU posted a photo featuring a snack truck sent by Korean fried chicken brand Puradak to support her during filming. Dressed in a crisp white blouse layered under a sleek vest, with her hair tied back neatly, IU showcases polished elegance, giving fans a preview of her character.
The post created a buzz among fans, as it marks the first time IU has revealed herself in costume as Seong Hee Joo, the lead role in the highly anticipated drama.

Set in an alternate version of present-day South Korea ruled by a constitutional monarchy, the Friday–Saturday series follows Seong Hee Joo (IU), a wealthy chaebol heiress who seems to have it all, except noble status, a fact that deeply frustrates her. Her counterpart is Grand Prince Lee Ahn, played by Lovely Runner star Byeon Woo Seok, a royal who has blue blood but no power or privilege to show for it.
Together, their characters navigate love, politics, and identity in a romantic drama that fuses class commentary with a modern royal twist.
IU’s transformation into the glamorous yet headstrong Seong Hee Joo is already drawing attention, with fans eagerly awaiting her performance and eye-catching fashion in what promises to be a highly anticipated series.
