Your other half will be this entire nation." The drama The Grand Duchess of the 21st Century, which aired amid enormous buzz, is now being released as an unedited official script book. Set in a uniquely imagined Korea that maintains a constitutional monarchy, The Grand Duchess of the 21st Century follows the love and choices of Seong Hui-ju, the daughter of Korea's top conglomerate family who repeatedly hits the wall of being a "commoner," and Grand Prince Ian, the king's son who can never fully possess anything of his own.

Scenes that played out on screen through glances and silence are brought back to life through actual dialogue and detailed stage directions, allowing readers to more clearly understand the characters' emotions and the reasons behind their choices. The book includes writer's commentary that reveals the intent behind each episode, the writer's picks for memorable lines and scenes, high-resolution stills, and an exclusive writer interview—recreating the excitement and lingering emotion of the drama in print. For the first time, behind-the-scenes materials that complete the constitutional monarchy world of The Grand Duchess of the 21st Century are also revealed, including the royal family and royal school design logos, the marriage contract glimpsed on screen, and the full scandal article. The cover of Volume 1 features the blue associated with Blue Dragon Palace's Grand Prince Ian, while Volume 2's cover features the red associated with Vermilion Bird Palace's Seong Hui-ju. Both volumes are packaged together in a case inspired by the royal "Sun, Moon, and Five Peaks" mother-of-pearl jewelry box motif, adding to its collectible value.
