The K-drama Perfect Crown drew criticism for its inaccurate portrayal of Joseon court rituals in episode 11, which aired on May 15. The scene showed Grand Prince Yi An wearing the Guryu Myeonryugwan crown while officials chanted “Cheonse,” a phrase signifying vassal state allegiance rather than independent sovereignty [1, 2]. Experts noted the crown’s use was historically incorrect; the Guryu Myeonryugwan was not worn by emperors. Instead, the sovereign’s crown was the Sibi Myeonryugwan, distinguished by 12 jade strands [1, 2].
On May 16, the production team issued a formal apology on their official website. They admitted "insufficient research into Joseon court rituals" and promised to revise audio and subtitles for future releases. They said, "We sincerely bow our heads in apology to the many viewers who have supported the drama with affection for the concerns caused by issues surrounding the worldbuilding and historical accuracy" [1].
The day after, actors IU and Byeon Woo Seok posted personal apologies on Instagram. IU stated, "My heart remains heavy even now. I sincerely reflect and apologize without excuse for not contemplating more deeply regarding the historical accuracy issues pointed out by viewers and proceeding with my role as an actor" [2]. Byeon Woo Seok added, "I took time to reflect on myself after reading the audience’s feedback. I’ve realized once again that as an actor, I need to go beyond just acting and take responsibility for understanding the message and context of the work I’m part of" [2].
The controversy focused on the ceremonial details, such as the incorrect use of the Guryu Myeonryugwan and officials chanting "Cheonse," which historically signified vassalage. These elements contradicted historical records of Joseon dynasty practices [1, 2].
The drama’s script book is scheduled for release on May 31. Publisher O’Fanhouse Studio confirmed it is coordinating with the production team to revise the disputed ceremonial terminology before publication [1].
