tvN’s upcoming weekend drama 100 Days of Lies (100 Days of Deception) has unveiled a first look at its passionate script reading, offering a glimpse of the intense performances and complex relationships that will drive its 100 day spy romance.
Set to premiere on October 10 at 9:10 PM KST, 100 Days of Lies follows a master pickpocket from Gyeongseong who becomes an undercover spy and crosses paths with an elite interpreter working for the Japanese colonial government. As their paths collide at the heart of the enemy’s territory, the drama combines espionage, romance and historical tension in a story where every word may conceal a truth, a lie or a dangerous secret.
The drama is directed by Yoo In Sik, known for his work on Dr. Romantic and Extraordinary Attorney Woo, and written by Ryu Bo Ri, whose previous credits include Do You Like Brahms?. Their collaboration has made 100 Days of Lies one of the highly anticipated historical dramas of the upcoming season.
Kim Yoo Jung and Park Jin Young Lead a Dangerous 100 Day Romance
The script reading brought together director Yoo In Sik, writer Ryu Bo Ri and an impressive ensemble cast including Kim Yoo Jung, Park Jin Young, Kim Hyun Joo, Lee Moo Saeng, Jin Sun Kyu, Lee Ki Young, Choi Duk Moon, Seo Jung Yeon and Kim In Kwon.
Before beginning the reading, the cast and production team observed a moment of silence to honor the sacrifices of independence activists. The meaningful start was followed by an energetic reading that showcased the emotional depth and chemistry of the characters.
Kim Yoo Jung takes on the role of Lee Ga Kyung, Gyeongseong’s most skilled pickpocket who disguises herself as an interpreter trainee at the Japanese colonial government for 100 days. Dreaming of traveling to America, Ga Kyung initially appears bold, clever and fearless. However, after becoming an undercover operative for the resistance organization Gukgukdan, she is forced to confront increasingly dangerous situations that change her life.
Kim Yoo Jung reportedly captured the character’s many sides during the reading, moving naturally between Ga Kyung’s playful confidence and the fear and determination that emerge as her mission becomes more perilous.
Park Jin Young plays Kim Tae Woong, an elite interpreter fluent in three languages who is also known as Sato Hideo, the adopted son of the government’s powerful political official. Despite his polished appearance and exceptional linguistic abilities, Tae Woong carries a private sorrow that he cannot share with anyone.
Park Jin Young brought a restrained emotional intensity to the role, hinting at the complicated inner world hidden behind Tae Woong’s composed exterior.
Most notably, Kim Yoo Jung and Park Jin Young displayed remarkably natural chemistry despite this being their first on screen pairing. Their immediate rapport has heightened anticipation for the 100 day espionage romance that will unfold between Lee Ga Kyung and Kim Tae Woong.
Kim Hyun Joo and Lee Moo Saeng Add Another Layer of Intrigue
The drama’s central conflict extends far beyond its main romance.
Kim Hyun Joo plays Yoo So Ran, a sharpshooter belonging to the anti Japanese resistance organization Gukgukdan. Driven by a desire for revenge, So Ran becomes involved in a mission to assassinate Sato Shinichi, the second most powerful figure in the Japanese colonial government.
When her operation reaches a critical point, So Ran proposes a life changing deal to Lee Ga Kyung, making her an important catalyst in the story. Kim Hyun Joo brings both explosive intensity and controlled restraint to the character, emphasizing the emotional wounds and determination beneath So Ran’s hardened exterior.
Lee Moo Saeng stars as Yoo Philip, a Gyeongseong correspondent for an American newspaper. Using his position as a journalist, Philip puts pressure on powerful officials while secretly working as a member of Gukgukdan.
He also hides his feelings for Yoo So Ran behind a fabricated marriage. His outwardly composed persona contrasts with the deep affection he quietly carries, allowing Lee Moo Saeng to explore both the character’s cold determination and his more vulnerable side.
Jin Sun Kyu Plays the Drama’s Chilling Antagonist
Jin Sun Kyu takes on the role of Sato Shinichi, the second most powerful figure within the Japanese colonial government and Gukgukdan’s primary assassination target.
Sato is an ambitious man who will stop at nothing to achieve success and advance his position. During the script reading, Jin Sun Kyu reportedly established the character’s intimidating presence through a cold gaze and measured delivery, immediately creating tension around every scene involving him.
With Sato standing at the center of the resistance group’s assassination plot, his conflict with the other characters is expected to become one of the drama’s major sources of suspense.
A Strong Supporting Cast Expands the Story
100 Days of Lies also features an extensive supporting cast whose characters represent different sides of Gyeongseong’s complicated political and social landscape.
Lee Ki Young plays Kim Seung Eok, the owner of Joseon’s largest textile company, while Seo Jung Yeon portrays Ryu Gwan Sil, Sato’s Korean housekeeper.
Kim Do Hyun appears as Suzuki, an English interpreter working for the Japanese colonial government. Go Han Min plays Mitarai, another government official, while Kim Joong Hee takes on the role of Fukuda, chief of the government’s police bureau.
Kouri Yuka plays Yamada, Sato’s secretary, while Hong Sa Bin portrays Inoma, Lee Ga Kyung’s partner in crime from her days as a pickpocket.
The drama’s resistance group, Gukgukdan, is similarly packed with experienced performers. Choi Duk Moon plays Gwak Woon Hak, Kim In Kwon plays Han Cheol Ryong, Jeon Seok Chan plays Kim Chi Geon, Jeon Yung Beop plays Song Jeon, Kim Dong Young plays Park Se Hwan, Lee Do Gun plays Jang Jung Yeop, Park Jung Yeon plays Kim Myung Nam, Lee Sun plays Lee Young Bok and Go Se Bin plays Hwang Gyu Young.
Their characters are expected to form another crucial axis of the story as the resistance movement works against the powerful figures controlling the colonial government.
An Espionage Romance Where Every Word Can Hide a Secret
One of the most distinctive elements of 100 Days of Lies is its use of interpretation as a storytelling device.
Because the characters come from different nationalities, organizations and linguistic backgrounds, communication itself becomes a source of suspense. An interpreter does more than simply translate words; they can uncover hidden intentions, conceal information or manipulate the meaning of a conversation.
The drama takes that concept further by placing a resistance operative inside the enemy’s heart while surrounding her with characters whose loyalties are rarely as straightforward as they appear.
This creates an atmosphere in which a single conversation could expose a secret, a carefully chosen word could change an alliance and a seemingly innocent lie could determine whether a character survives.
100 Days of Lies Promises a Different Kind of Historical Romance
The production team said the script reading was a meaningful opportunity for everyone involved to reflect on the drama’s themes and message. They also expressed hope that the sincerity of the cast and crew would reach viewers, describing the series as a story about ordinary people who refused to lose sight of hope for independence during one of the darkest periods in Korean history.
With Yoo In Sik’s acclaimed direction, Ryu Bo Ri’s character driven writing and a large ensemble of talented actors, 100 Days of Lies is shaping up to be more than a conventional historical romance.
Its combination of undercover espionage, forbidden emotions, political intrigue and the hidden meanings behind language gives the series a distinctive premise. At the center of it all are Lee Ga Kyung and Kim Tae Woong, two people who meet on opposite sides of a dangerous world where trust can be as valuable as information.
100 Days of Lies will premiere on October 10 at 9:10 PM KST on tvN. As the countdown begins, attention is now turning to whether the drama can successfully blend historical storytelling, spy thriller tension and romance into one compelling 100 day journey.
