The King's Affection, a drama about a man living with a king, reaches 10 million viewers.

As the movie 'The King and the Man' is on the verge of surpassing 10 million viewers, interest in King Danjong, the 6th king of Joseon who is the background of the movie, and the history of the Joseon royal family is leading to book sales. In the month following the movie's release, sales of books with the keyword 'Danjong' increased by 2565.4% compared to the same period last year. Sales of various genres, including children's history books, the Annals of the Joseon Dynasty, and the classic novel 'Danjong Aesa,' have also increased.

In particular, the classic novel 'Danjong Aesa' by Yi Gwangsu has seen its sales increase by about 80 times compared to the same period last year, gaining popularity. 'Danjong Aesa,' published by Saeum Publishing in February of this year, is currently ranked first in sales among books with the same title and has shown a steady upward trend since its release. An edition of 'First Edition 'Danjong Aesa',' which restores the cover design of the 1954 first edition, is also receiving high interest.

The popularity of books related to King Danjong is also prominent in the children's history book category. The children's history book 'Tears of the Young King' ranked first in sales for books with the keyword Danjong, with a 4614.3% increase in sales compared to the same period last year. The recently published 'Naked Korean History 12, The Tragic Siblings, Danjong and Princess Gyeonghye' also saw a significant increase in sales, reflecting the interest in Danjong's story.

The movie's success is expanding interest beyond the figure of Danjong to the era and historical background in which Danjong lived. Sales of 'Annals of the Joseon Dynasty Vol. 3: Sejong, Munjong, Danjong' increased by about 800% (about 9 times) compared to the same period last year, and sales of 'Danjong's Sorrow, Sejong's Tears' also rose by about 2700% (about 28 times) during the same period. This is analyzed as an increase in reading demand to deeply understand the history and political background of the Joseon royal family, prompted by the movie.

The head of Yes24's Book Business Division stated, "Cultural content such as movies and dramas consistently sparks interest in specific historical figures or events, leading to a trend of readers seeking out and reading related books."
