The story, without the spoilers.
Gyeongseong, 1932. Korea is under Japanese colonial rule, and Lee Ga-kyung is the city's best pickpocket, a woman whose only dream is to earn enough money to leave for America. Instead she is recruited by an independence cell and given a false identity, a new name and a post as an interpreter inside the enemy's inner circle. Her partner in the deception is a bilingual interpreter living his own double life, and neither of them can afford to trust the other completely. Every coded message, every stolen glance and every lie buys them another day, but the mission has a deadline: one hundred days. Kim Hyun-joo plays the handler who keeps the operation alive. 100 Days of Deception premiered October 10, 2026, on tvN, airing Saturdays and Sundays with sixteen episodes and streaming on Netflix and TVING. It is a period spy romance with action, tension and a heroine who steals every scene she is in.
A little curiosity. A new favourite.
