tvN Announces New Period Spy Romance Drama 100 Days of Lies Starring Kim You-jung and Jinyoung
Slated to premiere on October 10 at 9:10 p.m., tvN’s upcoming weekend drama ‘The 100-Day Lie’ stars Kim Yoo-jin and Park Jin-young in a 100-day espionage romance set during the Japanese colonial period, pairing the director of the 27.6% hit ‘Romantic Doctor, Teacher Kim’ with a sprawling cast of veterans.
Script Reading Session Unveils Cast and Production Team for October Premiere
Production for tvN’s new weekend drama ‘The 100-Day Lie’ is officially underway following a formal script reading session in Seoul. According to coverage from TenAsia, the project brings together director Yoo In-shik—celebrated for his work on the high-rated series ‘Romantic Doctor, Teacher Kim’ and ‘Extraordinary Attorney Woo’—alongside writer Ryu Bo-ri, who previously penned ‘Do You Like Brahms?’. Before diving into the script, the cast and crew observed a moment of silence to honor the sacrifices of independence activists, establishing a serious tone for the historical drama.
The narrative centers on a complex infiltration plot set inside the Japanese Government-General of Korea. The plot pits a top pickpocket from Gyeongseong against an elite government interpreter in a 100-day espionage romance. By leveraging the act of interpretation—where truth, lies, and hidden motives intersect—the series aims to deliver distinct suspense against an era of severe national turmoil.
Character Dynamics and Star-Studded Cast in Colonial-Era Gyeongseong
Kim Yoo-jeong takes on the lead role of Lee Ga-gyeong, a premier pickpocket in Gyeongseong who finds herself operating under deep cover as a temporary interpreter inside the Japanese Government-General for a 100-day window. The character balances a desperate dream of escaping to America with the immediate, high-stakes danger of acting as a secret agent for the group known as Ggugukdan. Opposite her, Park Jin-young plays Kim Tae-woong, an elite government interpreter and the adopted son of the administrative superintendent, operating under the alias Sato Hideo. Proficient in three languages, Tae-woong hides deep personal sorrow behind a polished bureaucratic exterior.
The expansive supporting ensemble anchors the political and militant factions of the period drama. Kim Hyun-joo portrays Yu So-ran, a sniper for the anti-Japanese group Ggugukdan who issues a life-or-death ultimatum to Lee Ga-gyeong during an assassination plot against Sato Shin-ichi. Lee Moo-seung stars as Yu Philip, a Gyeongseong special correspondent for an American media outlet who uses his press credentials to pressure the administration while hiding an enduring, protective devotion to Yu So-ran through a strategic, concealed marriage.
Jin-soon Gyu steps into the role of Sato Shin-ichi, the second-in-command at the Government-General and the primary target for the resistance. Rounding out the institutional and underground factions, veteran actors including Lee Ki-young as textile tycoon Kim Seung-eok, Seo Jeong-yeon as Sato’s Korean housekeeper Ryu Gwan-sil, and Choi Deok-moon as Ggugukdan member Gwak Un-hak add granular depth to the sprawling production.
Strategic Production Value and Historical Context
The project explores the intersection of individual survival and collective resistance, capturing how ordinary citizens managed to preserve hope during a dark historical chapter. Production representatives noted during the script reading that the core intention of the series is to translate the genuine sincerity of the cast’s performances into an authentic emotional resonance for viewers.
