I heard the official script book for 'The Grand Prince's Wife of the 21st Century' is being published! Haha.

“The emotion beyond the drama, the release of the complete script book for '21st Century Grand Prince's Wife' is coming soon!” they announced.
The script book includes unreleased side stories, high-definition still cuts of memorable scenes, behind-the-scenes stories of 'Seong Hee-ju x Grand Prince Lee An,' and the actors' handwritten signatures. I heard pre-orders open on the upcoming 28th! Hahaha.
