Singer and actress IU shared behind-the-scenes photos from '21st Century Grand Duchess'.
On the 18th, IU posted photos taken on the set of the MBC Friday-Saturday drama '21st Century Grand Duchess' (hereinafter 'Grand Duchess') on Instagram, captioning them "2nd and 3rd episode behind-the-scenes".
In the photos, IU, dressed as Seong Hee-ju, the CEO of Castle Beauty in the drama, exuded a luxurious and elegant atmosphere befitting a chaebol.
In the broadcast on the 17th, IU was seen in a warm and friendly manner with the actors who played the students who committed the 'egg-throwing incident' against Hee-ju, drawing attention.


In that day's broadcast, after a scandal erupted between Hee-ju and Prince Lee An (played by Byun Woo-seok), Hee-ju was subjected to an egg-throwing incident by Lee An's fans in a parking lot. However, Hee-ju did not yield at all and sharply scolded the students. Lee An, who overheard the scene during a phone call, expressed concern for Hee-ju's condition and brought her to his private residence.
Fans who saw IU's behind-the-scenes photos encouraged her with comments such as "So beautiful, like sunshine" and "Unnie who looks great in the yellow chick outfit".
Meanwhile, in the 'Grand Duchess' ending of that day, Hee-ju and Lee An shared their first kiss over a wall, signaling a rapid progression in their romance.
