The tvN (a major Korean cable network) Saturday-Sunday drama '100 Days of Lies,' starring Kim Yoojung and Park Jinyoung (박진영) of GOT7, achieved a 9.0% viewership rating on paid platforms by its fourth episode, ranking first in its time slot. According to a WoW!Korea report, it started with a 5.3% premiere rating and is steadily gaining traction, with a Maeil Business Newspaper report stating its highest rating climbed to 10.6%. This drama tells the story of Lee Gakyung (이가경), a female spy (Kim Yoojung) who infiltrates the Japanese Government-General of Korea in Gyeongseong (경성, the colonial-era name for Seoul) during the Japanese colonial period in 1932, offering both romance and historical tension.
According to a Futabanet report, '100 Days of Lies' was released exclusively on Netflix and achieved significant international success, topping the charts in 108 countries on Rakuten Viki, earning it the nickname 'TVING's Filial Daughter' (a term of endearment for a successful show on the Korean streaming platform TVING). In the FUNdex (팬덱스) buzz ranking for the third week of October, it fiercely competed with 'Doctor X,' trailing by only 2.07 points, and in the cast category, Kim Jiwon and Kim Yoojung secured the 1st and 2nd spots, respectively. The drama, conceived by writer Ryu Bori (류보리) over approximately five years and with Studio Dragon involved in planning and development since 2024, also put considerable effort into the actors' foreign language performances. Kim Yoojung received Japanese and English acting coaching, while Park Jinyoung repeatedly practiced his foreign language lines. Notably, Jin Seonkyu (진선규), who plays Japanese Governor-General Sato Shinichi, reportedly stayed in Japan for two months, practicing his script for about seven hours a day.

While the eras and settings of the two dramas differ, they share a common character archetype: a female protagonist who acts on her own judgment rather than conforming to an organization, creating cracks in immense power. According to a WoW!Korea analysis, this archetype resonates with viewers by reflecting changes in the portrayal of female protagonists in Korean dramas and the sense of confinement experienced in modern society. K. Soo-jung of 'Doctor X' is not a woman striving for recognition within an organization, but one who is indispensable to it, showcasing a reversal of power that provides a thrilling sense of satisfaction. Similarly, Lee Gakyung of '100 Days of Lies' portrays an autonomous figure whose fate isn't changed by romance, but rather where love becomes a part of her life within choices made for survival.
A broadcasting official analyzed, "Both dramas tap into the deep fatigue the public feels towards old systems." The uncompromising surgeon and the spy who uses even romance as a weapon for survival are hailed as modern dark heroes who challenge irrationality and symbols of autonomous female narratives. The active role of such powerful female characters has become a significant trend in recent K-dramas, and it's also noteworthy that both dramas were produced by Studio Dragon.
'Nation's Little Sister' Kim Yoojung's Mature Transformation and Expanded Acting Spectrum
Kim Yoojung, who was strongly associated with the 'Nation's Little Sister' (국민 여동생, a term for young female celebrities who are widely beloved) image, recently captivated the public by revealing a more mature and elegant visual in an off-the-shoulder dress, as reported by the Chosun Ilbo Japanese edition. Born in 1999, making her 27 this year, she has steadily grown since her debut in a Crown Sando commercial in 2003.
Kim Yoojung's acting transformation was particularly prominent in her previous work, the TVING (a Korean streaming platform) original drama 'Dear X.' According to a WoW!Korea report, she successfully changed her previous image significantly by playing Baek Ajin (백아진), a villainess determined to reach the top even if it meant trampling on others. This drama ranked #1 in new paid subscriber contribution among TVING original works for six consecutive weeks and also topped both viewership hours and completion rates among all TVING original works, earning it the nickname 'TVING's Filial Daughter.' This success proves Kim Yoojung's broad acting spectrum and presence as an actress, to the extent that writer Ryu Bori (류보리) mentioned at the '100 Days of Lies' production press conference, "We needed an actress who could captivate viewers."
New Protagonists of K-Drama: Social Messages and Global Expansion
Kim Jiwon and Kim Yoojung are bringing a fresh wave to K-dramas with their powerful narratives and acting skills. Their impact extends beyond mere viewership ratings, positively influencing content creation centered around the 'female dark hero' keyword. According to a WoW!Korea analysis, despite controversies such as 'Doctor X's' depiction of medical practices and '100 Days of Lies' being labeled an 'anti-Japanese drama' in Japan due to its historical perspective, both dramas maintain high viewership and buzz, raising important social questions.
In the case of '100 Days of Lies,' it draws inspiration from real historical events like the anti-Japanese independence movements of Lee Bongchang (이봉창) and Yoon Bonggil (윤봉길) and the Jeam-ri Massacre (제암리 학살 사건), adding depth to its spy drama and sparking interest in 1920s Korean history among international reaction video creators. These dramas, led by the two actresses, offer viewers both exhilaration and comfort, successfully addressing both social messages and global expansion as new protagonists of K-drama.
