A pickpocket-turned-spy. An interpreter with a double identity. And a hundred days where neither of them can afford to trust the other.
tvN’s upcoming period drama 100 Days of Deception has just released a new poster, and it captures exactly the kind of charged, wary intimacy that’s about to define the show — Park Jinyoung and Kim You Jung standing close enough to feel the tension, neither one willing to fully look away.

What’s the Story?
Set against the backdrop of the Japanese occupation of Korea, the drama follows Lee Ga Kyeong (Kim You Jung), the top pickpocket in Gyeongseong — present-day Seoul — who transforms into an undercover spy for the independence movement. Her mission leads her straight into the heart of the enemy: the Japanese Government-General of Korea.
There, she becomes entangled with Kim Tae Woong (Park Jinyoung), an interpreter who goes by the alias Sato Hideo and is the adopted son of the Inspector-General of Korea — the second-highest-ranking official in the entire administration. Their paths crossing isn’t just risky romance; it’s a direct collision between a spy and someone embedded deep within the system she’s trying to undermine.

What the New Poster Reveals
The freshly released poster leans hard into that tension. It captures an unusually quiet moment between the two characters, left alone in an office where Kim Tae Woong closes the distance, approaching Lee Ga Kyeong without breaking eye contact. She, in turn, avoids his gaze and takes a step back, visibly on guard.
Accompanying the image is a loaded line of dialogue from Kim Tae Woong: “Just once, tell me a real story that isn’t a lie.” Whether that’s a genuine plea or a quiet warning is left deliberately ambiguous — and it sets the tone for a relationship built entirely on mutual suspicion.
A Romance Built on Lies
According to the production team, the show’s emotional core lies in how Lee Ga Kyeong and Kim Tae Woong become entangled through secrets neither of them wants exposed, nor fully believes from the other. As the production team put it, the process of feelings growing amid deception slowly becoming genuine is meant to deliver both a nervous excitement and real emotional weight.
Why This Drama Is One to Watch
Period spy romances carry inherent stakes — every conversation is a potential trap, every trust a possible betrayal. Pairing that structure with two leads playing characters on opposite sides of a national struggle gives 100 Days of Deception a compelling emotional tightrope to walk, especially under a director known for balancing sharp writing with genuine heart in shows like Dr. Romantic.
