100 Days of Deception Trailer Releases: There is something that appears deeply suspicious about a woman saying “I like you ever since we first met” while crossing her fingers behind her back, and that is the vibe the 100 Days of Deception trailer has set.
The upcoming Korean series 100 Days of Deception (100일의 거짓말) drops its trailer like a handful of scattered clues rather than an actual explanation. There are stolen secrets, a dangerous infiltration, the Japanese colonial government, a man who appears to be the target and a woman who seems increasingly incapable of separating the person she is pretending to be from the actual person she is.
The trailer moves quickly, and so does the woman, and the speed matters
100 Days of Deception Trailer Releases: A Pickpocket Walks In
The premise gives a complicated setup: set during the Japanese colonial period, 100 Days of Deception (100일의 거짓말) follows Gyeongseong’s top pickpocket, Lee Ga-gyeong, as she infiltrates the Japanese colonial government intending to steal secrets, hoping to secure freedom, except that she falls for the son of her target.
The trailer does not seem interested in giving us the clean, comfortable version of the story where we know who is lying, who is being manipulated and who is genuinely falling in love; everything rather feels very slippery.
The protagonist is constantly moving: she runs, sneaks, observes, reacts and disappears into spaces where she clearly does not belong. Even when she is standing still, there is a sense that she is mentally calculating her next move. There seems almost no room for her to “just be”, and that becomes one of the trailer’s most interesting visual details.
Her Face Says More Than Her Dialogue
The woman, Lee Ga-gyeong, at the centre of 100 Days of Deception rarely looks completely comfortable. There is a constant fear in her expression: not necessarily the dramatic fear that announces danger but something quieter and more unsettling.
She is not merely telling lies; she is living inside them, and the trailer repeatedly emphasises that through her movements. Her actions are quick and restless, as though slowing down might give someone time to notice that something is wrong about her.
The Trailer Feels Intentionally Fast
There is a kind of irony in how the trailer presents Lee Ga-gyeong. She is supposedly one of Gyeongseong’s top pickpockets, so we naturally might expect clever, controlled moves, but the trailer gives us very little to nothing of that sort.
It instead gives urgency: the pacing seems deliberately fast, throwing images and moments at us before we can comfortably put them together. Just when one scene starts to offer some context, the trailer moves away.
We are not given any answers because she does not seem to have the luxury of knowing how this story will end either, and the trailer seems to be wanting us to experience her world the way she experiences it.
The Final Frame Is Basically A Warning
Then comes the trailer’s best little twist. She tells Sato Hideo, “I like you ever since we first met”. Seems cute!
But she says this with her fingers crossed behind her back. It is such a tiny gesture but it changes the entire sentence as without it the line could be romantic but the line becomes suspicious with it.
100 Days of Deception Looks Like It Will Make Lying an Emotional Language
The trailer seems embedded into the protagonist’s entire existence: she lies to survive, hides to complete her mission, performs another identity to get close to her target and then somewhere along the way she starts developing feelings, but no one knows if they are true.
The title suddenly feels less like a description of the plot and more like a question: what happens when you spend 100 days pretending to be someone else and accidentally get emotionally connected to the person you are supposed to deceive.
The Trailer Gives Us Questions, Not Answers
100 Days of Death gives us the atmosphere where questions fall like rainfall: a woman who is constantly hiding without telling us exactly what she is hiding from whom.
It gives us romance without confirming whether the romance is genuine; danger without showing us its full shape; and a protagonist whose face seems to know considerably more than the trailer is willing to tell us.
