The series will star beloved actress Kim Yoo-jung and actor-singer Park Jin-young in the lead roles, along with a powerful supporting cast including Kim Hyun-joo, Lee Moo-saeng, and Jin Seon-kyu. The drama is already gaining attention for its intriguing premise, impressive cast, and historical backdrop.

Set during a turbulent time in Korean history, 100 Days of Lies tells the story of a dangerous romance that unfolds amid espionage and the fight for independence. The drama centers on Kyungsung’s most skilled pickpocket who eventually becomes a spy. His life takes a dramatic turn when he crosses paths with an elite interpreter who works under the Japanese Governor-General of Joseon. As their worlds collide, the two characters become entangled in a complicated relationship filled with secrets, deception, and growing feelings.

While the two leads initially come from completely different sides of the political divide, their connection begins to deepen as they navigate a dangerous world of intelligence missions and undercover operations. With the stakes rising around them, they must decide whether their loyalty lies with their duty or their hearts. The drama promises to blend romance, suspense, and historical struggle into a compelling narrative about love, sacrifice, and the pursuit of freedom.

The casting announcement alone has generated huge excitement among viewers. Kim Yoo-jung is widely loved for her ability to portray emotional and layered characters. She gained massive popularity through historical and fantasy dramas such as Love in the Moonlight and the romantic fantasy series My Demon. Her return to a historical-style project has fans eager to see her once again in a powerful period role.

Opposite her, Park Jin-young brings both acting skill and star power. The singer-actor from the K-pop group GOT7 has steadily built a strong acting career with memorable performances in dramas like The Devil Judge and Yumi’s Cells. His casting as a complex character in a historical spy romance has already sparked curiosity about the chemistry between the two leads.

The supporting cast further strengthens the drama’s appeal. Veteran actress Kim Hyun-joo, who impressed audiences in Hellbound, is known for delivering powerful and emotionally rich performances. Lee Moo-saeng, recognized for his role in The Glory, is expected to add intensity and depth to the storyline. Meanwhile, Jin Seon-kyu, widely praised for his performance in the hit film Extreme Job, will bring his charismatic screen presence to the ensemble.

With a storyline that mixes historical tension, espionage, and emotional romance, 100 Days of Lies is shaping up to be one of the most anticipated Korean dramas of 2026. Historical dramas centered on Korea’s independence period have often resonated deeply with viewers because they combine personal stories with significant national events. This drama appears ready to explore the sacrifices and hopes of people living through a defining moment in history.

The tagline revealed alongside the announcement hints at the series’ emotional and patriotic tone, inviting viewers to witness “the brilliant light of liberation.” Such a message suggests that the drama will not only focus on romance but also highlight the dreams and determination of those striving for freedom.

With a captivating storyline, a talented cast, and a powerful historical backdrop, 100 Days of Lies already looks like a drama that fans of romance, suspense, and period storytelling will not want to miss.
