What Is Perfect Crown About?
Set in an alternate universe where modern-day Korea is a constitutional monarchy, “Perfect Crown” tells the love story of Seong Hui Ju (IU), a chaebol heiress who has everything but is only a commoner in status, and Grand Prince Ian (Byeon Woo Seok), a prince who has nothing despite being the son of the king.
The premise is a delicious class-reversal romance wrapped in royal intrigue — the kind of setup that Korean dramas have mastered over decades, now elevated by two of the industry’s most beloved stars.
