Kim Yoo-jung’s “100 Days of Lies” Hits 10.6% for tvN

Episode 4, which aired on the 18th, peaked at 10.6% among households in the Seoul area, with an average of 9.8%. Nationwide, it averaged 9.0% and peaked at 9.8%. Both figures beat the show's previous records.

The episode ranked first in its time slot across all channels, including terrestrial networks, and topped the 2049 demographic, tvN's core target audience. Two weeks after premiering, the show is on a clear upward trend.

Part of the buzz comes from its status as a tvN 20th anniversary special. The original flagship of the celebration was supposed to be "Signal 2," the sequel to the cult hit "Signal." But its schedule was pushed back indefinitely after lead actor Jo Jin-woong's past misconduct came to light and he announced his retirement. Some in the industry see "100 Days of Lies" as effectively filling that gap. Director Yoo In-sik pushed back at the press conference, saying the changes to the other project have nothing to do with this one and that the drama was prepared on its original timeline.

The story takes place in 1930s Seoul, then known as Gyeongseong under Japanese colonial rule. Lee Ga-gyeong (Kim Yoo-jung), a famous pickpocket, becomes an informant for an independence group called Gukgudan and goes undercover as an interpreter at the Japanese colonial government. Park Jin-young plays Sato Hideo, a man with a double identity who creates tension for her, while Kim Hyun-joo, Lee Moo-saeng and Jin Seon-kyu play figures on both the group's side and the government's. In episode 4, the group's second assassination attempt goes sideways, and Ga-gyeong's cover is closer than ever to being blown.
