It seems to raise the immersion in the central narrative of 'The Grand Prince's Wife'!

The changes in the relationship with Grand Prince Yi An were depicted in earnest. IU, playing the role of Seong Hee-ju, heightened the drama's immersion by intricately portraying everything from her wavering inner self to her resolute determination and poignant love. I think she really acts so well. IU is someone you can trust and watch! Hahaha.
