The transformation from modern heiress to royal consort is no simple feat, and IU is giving fans a front-row seat to the process. In a new, highly anticipated installment of [IU TV], the superstar offers a deep dive into her role as Seong Hui-ju in the hit MBC drama Perfect Crown (21세기 대군부인).
The episode, titled “The Day Seong Hui-ju Became Royal,” pulls back the curtain on the elaborate world-building required to bring a 21st-century constitutional monarchy to life.
The Making of a Modern Royal
The featurette focuses on the pivotal "wedding day" sequence—a moment that recently sent the show’s viewership ratings soaring to a peak of 14.3%. Fans are treated to an intimate look at:
- The Traditional Grandeur: Behind-the-scenes footage of IU undergoing the rigorous "health checkups" and elaborate hanbok fittings required for her character’s entry into the palace.
