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 Sung Hee-joo (IU), a chaebol heiress who has everything but is only a commoner in status, and Grand Prince Yi An (Byeon Woo Seok), a prince who has nothing despite being the son of the king.

The tension is perfectly constructed from the start. Sung Hee-joo, the head of Castle Beauty, has beauty, ability, and wealth — but because the authority of the aristocratic class is so powerful, she constantly runs up against the limits of her status as a commoner and a child born out of wedlock. Prince Yi An wins the support of the Korean public thanks to his striking looks and innate dignity, yet he lives with himself hidden away due to his position as the royal family’s second son — a role in which he must neither shine nor raise his voice.

Two people caged by different kinds of powerlessness. It’s the perfect setup for a romantic drama.

The Marriage That Broke Korea

When Sung Hee-joo and Prince Yi An suddenly announce their marriage, 21st-century constitutional-monarchy Korea is thrown into an uproar. Amid rising suspicion about what truly lies behind the relationship, the newly released stills capture everything from their past and present to their future — tracing the path that leads them to become husband and wife. The Hollywood Reporter

New stills from their days as students at the Royal School together already have fans dissecting every frame, hunting for clues about how a commoner heiress and a deliberately invisible prince ended up walking down the aisle together — and why their announcement sent shockwaves through the entire nation.

Viewers are curious about what inevitable story could have led Sung Hee-joo and Prince Yi An to become a married couple despite the gulf in their social status. The Hollywood Reporter With IU’s proven track record in historical-adjacent dramas and Byeon Woo Seok fresh off the Lovely Runner phenomenon, the chemistry between these two is arguably the most anticipated on Korean television right now.
