The script of tvN’s hit drama “Hometown Cha-Cha-Cha“ has made a surprising appearance on the bestselling lists of local online book stores Aladin and Yes24, attesting to the popularity of the 16-part series that ended its run Sunday.

The final episode of the romantic comedy recorded a 12.7 percent viewership, the series’ highest rating, and a listing on Netflix’s Top 10 chart in more than 20 regions, including Hong Kong, Japan, Singapore, Taiwan, New Zealand and Australia.

Major online booksellers started taking pre-orders for the two-volume script of ”Hometown Cha-Cha-Cha“ on Oct. 7.

“We have been selling the scripts of popular dramas, but a drama script topping the bestseller list is rare,” an Aladin official told The Korea Herald.

According to the official, the script soared to the No. 1 spot on Aladin’s bestsellers list on Oct. 16.

The bookseller has sold drama scripts of many Korean hit series over the years, including SBS’ “Penthouse,” JTBC’s “Beyond Devil,” SBS’ “Hot Stove League,” and tvN’s “Stranger.” The last script that topped the bestseller chart was the script of Oscar-winning film “Parasite.”

“Passionate drama fans, who want to enjoy their favorite series a little longer and read the stories that were not in the broadcast are eager to purchase the original scripts. And the first editions are signed by the actors, making the books more memorable for some fans. More than 9,000 books were sold alone on the first day of our pre-order,” an official from Yes24 said in a phone call with The Korea Herald.

“The popularity of a film or drama naturally makes the viewers want to enjoy their favorite series in various ways. Similar to buying drama-related merchandise, buying an original script is becoming a way to show their love for a series that has ended,” the official said.

Special messages from both the author and the lead actors Shin Min-a and Kim Seon-ho are presented with the published drama script of “Hometown Cha-Cha-Cha.”

The script will be released on Nov. 9.
