Perfect Crown Controversy Explained: IU And Byeon Woo Seok Drama Faces Massive Backlash Over Historical Errors

Perfect Crown Controversy Explained: The backlash surrounding the K-drama 'Perfect Crown' has grown even stronger, with viewers now demanding the destruction of the drama’s official merchandise and script books instead of simple corrections. The controversy erupted after publisher Open House announced plans to revise the script book following criticism over historically sensitive expressions and ceremonial inaccuracies featured in the series. However, angry netizens believe the issue runs far deeper than a few errors, accusing the drama of mishandling Korean history, royal symbolism, and national identity despite its fictional setting.

Why Perfect Crown Sparked Massive Criticism

The controversy gained momentum after a coronation scene involving Grand Prince Ian, played by Byeon Woo Seok, aired in a recent episode. Viewers criticised the use of 'Cheonse' during the enthronement ceremony instead of the historically significant 'Manse', a phrase traditionally linked to Korean sovereignty. The royal costume design also drew backlash, with audiences pointing out that the crown used in the scene symbolised imperial officials rather than an emperor. Many viewers argued that these details reflected a careless approach towards historically meaningful symbols, especially in a drama marketed around royal politics and Korean identity.

Publisher Open House acknowledged the growing criticism and confirmed discussions with the production team about revising problematic expressions in the official script book. The company stated that future editions would include corrections, while existing buyers would receive revised PDFs, notices, and correction stickers.

Perfect Crown Backlash And Twitter Reactions

Many fans who initially anticipated the series expressed disappointment, claiming the drama prioritised glamorous romance over historical depth and cultural sensitivity. Netizens insisted that corrections were insufficient and called for the books and merchandise to be scrapped entirely.

Historical Inconsistencies Fuel Viewer Anger

Beyond the coronation controversy, viewers criticised the drama’s broader fictional world-building. Audiences questioned the portrayal of a modern constitutional monarchy that still maintains a hereditary class system and royal hierarchy. Critics also highlighted historical inconsistencies involving regency traditions and political structures inspired by the Joseon era.
