Kim You-jung and Park Jinyoung kick off tvN’s 20th-anniversary period spy drama with a stolen suitcase that sets off a chain of very dangerous lies.

100 Days of Deception Episode 1 Recap: Thieves, Spies, and a Very Bad Dinner
A Train Arrives in Keijo, and Pockets Get Lighter
The story opens in 1932 as Lee Ga-kyung steps off a train in Keijo (today’s Seoul) after a trip from Hoten (today’s Shenyang, China). She heads straight for the marketplace and starts lifting wallets and valuable ornaments, with Lee No-ma helping her work the crowd. It’s a slick, almost playful introduction to a girl who clearly does this for a living.
At the same station, Korean-American Yoo Philip, a correspondent for WWP News, is meeting his pregnant wife, So-ran, off the same train. Ga-kyung also spots Inspector Suzuki welcoming Inspector General Shinichi Sato and his wheelchair-bound daughter, Sonako, to the city. Suzuki mentions Philip to Shinichi, and the Inspector General promptly asks to have lunch with Philip and So-ran.
While the officials are busy being polite, Ga-kyung swipes So-ran’s bag. Then the police seal the station exits, and she’s forced to dash back onto the train, where she hangs a first-class compartment tag on the stolen bag. Mid-scramble, she bumps into Tae-woong (who goes by Hideo), who is carrying Sonako off the train. He soon realizes his wallet is gone and chases her, but Ga-kyung has already slipped out, and that first-class tag keeps the cops from stopping her.
She returns her rented dress to the shop and heads to the cottage of her boss, Ma Moon-mak, who collects the stolen goods from her, No-ma, and a few other kids. A drunkard shows up and threatens them, reminding Ga-kyung that she owes him for something she took.
Kkot-nim, a Stolen Suitcase, and the Money Dream
Back home, Ga-kyung and No-ma find some kids teasing Kkot-nim, a crippled orphan girl. They chase the bullies off, and No-ma tries to lift Kkot-nim’s spirits with made-up stories about how she lost her parents. Ga-kyung’s reaction is classic her: if he’s going to lie to the little girl, he should at least make it believable.
Across town, Philip brings So-ran to their shared house. She points out that they need to keep up appearances and share a bedroom in case anyone drops by, and she’s visibly anxious about the missing bag and what it could do to her cover. Meanwhile, Tae-woong rides in the car with Shinichi and Sonako, where the Inspector General asks about the wallet. At the Sato home, the maid, Yanagi, welcomes everyone and gets dinner going.
That night, Ga-kyung, No-ma, and Kkot-nim crack open the suitcase and find almost nothing worth keeping. There’s some white rice, which Ga-kyung plans to sell, because she’s saving up to move to America. Tae-woong’s wallet is just as disappointing: three won and a Tokyo Imperial University ID card showing he studied English Literature. She also finds a pawn shop receipt and tosses it. Then, while tucking the suitcase away, she discovers a secret vault stuffed with bullets, and her first thought is to sell those too.
Dinner at the Sato House and Two Sleepless Women
At the Sato table, Police Chief Fukuda brings up the pickpocket problem in Keijo. Tae-woong says he used to be one himself, before Shinichi found him. Shinichi clearly takes pride in the rescue story, calling the young man Hideo and bragging that he sent him to Tokyo Imperial University. But Tae-woong remembers a different version of that night, one where Shinichi killed his friend to teach him a lesson about stealing.
Later, So-ran lies awake thinking about the 13 years she has spent waiting to avenge her daughter’s death. Ga-kyung can’t sleep either; she remembers being thrown out of her home by her stepmother because she was illegitimate. Stepping outside, she runs into No-ma, who points out her tell: she crosses her fingers whenever she lies.
The Gugukdan Plot Comes Into Focus
The next morning, Ga-kyung takes the suitcase to the pawn shop. She mentions that she also has 50 bullets and asks what he’ll pay. When the owner offers 20 won, she figures the real rate must be 40. Elsewhere, Tae-woong is hunting for the English-speaking pickpocket who took his wallet and asks the police to notify him personally if they catch her.
At the Hanseong Medicine Clinic, So-ran and Philip meet their accomplices, Suzuki and Han Chul-ryong. Chul-ryong has brought rice, bullets, and a gun after hearing that So-ran’s bag was stolen. They talk about poisoning Shinichi’s food, since the Japanese have been taking white rice from local people. It turns out all four belong to the Gugukdan (the National Salvation Corps) and they’re plotting to kill Shinichi and free Korea from colonial rule. So-ran pictures herself shooting him, asks Suzuki to keep spying, and promises to protect the others if they get caught.
A flashback takes us three years back, to the moment So-ran recruited Philip while he was delivering money gathered by Koreans in America to support the independence effort.
Back in 1932, So-ran asks Philip to bury her in a hanbok, since she lost all her own clothes while changing identities. She loads the bullets into the gun Chul-ryong gave her as they prepare to host Shinichi for dinner the next evening. Before he arrives, Japanese guards ransack the house looking for weapons and search both So-ran and Philip.
The Dinner Party That Goes Sideways
Philip welcomes Shinichi, Tae-woong, and Suzuki to the table. Shinichi introduces Tae-woong as his son, and Tae-woong explains that he carries a gun to protect him. Then Shinichi says he suspects So-ran is Korean because of the way she counts on her fingers. Philip panics, and So-ran heads for the door when the bell rings.
It’s Ga-kyung, who has come to return the bullets for 60 won. She threatens to tell the Japanese soldiers about them, and So-ran, who doesn’t have the cash yet, has to ask her to wait. So-ran goes back to the table and claims their live-in maid has returned from an errand.
As everyone eats, Ga-kyung goes through the house and finds So-ran’s American passport, which she pockets. Philip, meanwhile, asks Suzuki, Tae-woong, and So-ran to leave him alone with Shinichi. So-ran and Suzuki go to the kitchen, while Tae-woong waits outside the dining room and runs straight into Ga-kyung. He recognizes her as the pickpocket and demands his wallet. She denies it, and he tells her to stop pretending.
Shinichi announces he has ordered a cake and steps out to the restroom. Tae-woong asks Ga-kyung to carry the cake in, while So-ran fills Philip and Suzuki in on Ga-kyung’s threat. The man delivering the cake is armed, and he orders Ga-kyung to lead him to the restroom so he can kill Shinichi. The episode closes on Ga-kyung trying to tell Tae-woong that someone is holding her at gunpoint.
My Review: Everybody Is Lying, and Ga-kyung Has the Least to Lose
This is a gripping opener, but I’ll be honest: I’m still not sure I understand what each character really wants. Nearly everyone on screen is deceiving someone. So-ran and Philip live under a cover, Suzuki feeds information to the Gugukdan, Tae-woong carries a name that isn’t quite his own, and Ga-kyung lies for a living. Of all of them, she seems to have the least to lose. She’s a petty pickpocket who somehow speaks fluent English and Japanese, and I keep wondering how she picked those up if she was thrown out of her house. I’m hoping the show answers that soon, because it’s the question I can’t shake.
I love the bond between Ga-kyung and No-ma, which gives the early scenes real warmth. But she’s made it clear that nothing, and nobody, outranks money for her, and after a life in poverty I understand why. That’s exactly what makes me curious about her and Tae-woong. Will she fall for him, or at least let him believe she has so she can get at his money? Tae-woong is completely at Shinichi’s mercy, and if we’re being honest, everyone around that table wants the Inspector General dead for a different reason.
What Works
- Ga-kyung’s introduction. The wallet lift, the stolen bag, and that first-class compartment tag trick show us how sharp she is without a single line of explanation.
- Tae-woong’s quiet pain. Shinichi tells a proud rescue story while Tae-woong remembers his friend’s death. The gap between those two versions says more than any speech could.
- The finger motif. Ga-kyung crosses her fingers when she lies, and So-ran’s finger-counting nearly exposes her to Shinichi. It’s a small, clever thread that ties two very different women together.
- The dinner sequence. Every storyline converges in one house, and the tension builds beautifully until that armed delivery man walks in.
- The cliffhanger. Ga-kyung trying to warn Tae-woong while a gun is at her back is a hard stop to cut away on. My jaw dropped.
What Doesn’t
- Murky motives. With so many agendas in play, it’s hard to tell who is lying for what reason. Some of that is clearly intentional, but I wanted at least one or two characters to feel fully anchored by the end.
- Ga-kyung’s languages. Her fluent English and Japanese are never explained, and that gap makes her feel a little too convenient for the plot, at least for now.
- A late-arriving wildcard. We don’t know what the delivery man is after. He seems shocked to see So-ran and Philip’s photo in the house, which makes me think he’s also gunning for Shinichi over something the Inspector General did years ago. That’s only a guess, but dropping a whole new player into the final minutes feels abrupt.
- A crowded cast. Aliases, accomplices, and officials arrive fast. A second viewing helps, but newcomers might need a minute to keep names straight.
Final Rating: 8/10
A tense, layered premiere with a magnetic lead and a killer final scene. A few fuzzy motivations keep it from a higher score, but I’m already hooked.
