Additional information:
The script 'The Grand Prince's Wife of the 21st Century' (aka Perfect Crown) by writer Yoo A In won the 'Excellence Award' at the 2022 'MBC Drama Screenplay Contest'. It is her first published script. A total of 997 works were submitted.
MBC is the original domestic broadcast studio for this series, which was produced in partnership with Disney+, who holds global streaming rights.
Psychofool:
The inspiration behind this show seems to be Princess hours. I see a lot of scenes in perfect crown are inspired by Princess hours
I'd be curious whether this came up during the discussions following the 2022 MBC script challenge. It's also possible that changes were made to the script during the production, which introduced the similarities to prior works that you & others have noted. 🧐🤔
