What Is 100 Days of Deception About?

The series takes place during the Japanese occupation of Korea, a period when Koreans faced colonial rule and resistance movements fought for independence. Gyeongseong, the former name used for Seoul under Japanese rule, provides the setting for a story filled with political tension and hidden identities.

At the center of the story is Lee Ga-kyung, a young pickpocket who is more interested in money than politics. She dreams of going to America and leaving her troubled past behind. Her life changes when she steals a bag belonging to Yoo So-ran, a woman whose respectable public image hides a dangerous secret.

The bag contains bullets connected to a plot against Inspector-General Shinichi Sato. Ga-kyung does not understand the full situation at first, but her decision to sell the bullets brings her directly into the conflict. Meanwhile, she crosses paths with Kim Tae-woong, also known as Sato Hideo, an interpreter who has personal ties to the powerful official.

The drama mixes espionage with romance and historical conflict. Rather than beginning with a trained spy, it follows an ordinary criminal whose talent for deception makes her unexpectedly useful to the resistance.

100 Days of Deception Episode 1 Recap

Ga-kyung Returns to Gyeongseong

The episode opens in 1932, as Ga-kyung returns to Gyeongseong by train from Hoten, now known as Shenyang in China. She quickly resumes her usual work, stealing wallets and valuable items with help from her companion, Lee No-ma.

The station is also welcoming several important arrivals. Korean-American journalist Yoo Philip meets his pregnant wife, Yoo So-ran, while Inspector-General Shinichi Sato arrives with his daughter, Sonako. Sato’s visit attracts attention from officials and police, creating a busy atmosphere in which Ga-kyung can operate.

Ga-kyung steals So-ran’s bag, unaware of its real importance. When the police begin closing the station exits, she uses a clever trick involving a first-class compartment tag to escape suspicion. During her escape, she also crosses paths with Tae-woong, who discovers that his wallet is missing.

A Pickpocket Who Wants to Escape Poverty

After returning to her usual surroundings, Ga-kyung hands over stolen goods to Ma Moon-mak, the man who controls a group of young pickpockets. His treatment of the children shows how difficult their lives are, with little room for safety or independence.

Ga-kyung and No-ma also look after Kkot-nim, a young orphan girl who has difficulty walking. Their concern for her reveals a softer side to two characters who spend much of their time stealing from others.

Despite their bond, Ga-kyung remains focused on earning enough money to leave Korea for America. Her past helps explain this determination. She was thrown out of her home by her stepmother, leaving her to survive without the security many other people take for granted.

When Ga-kyung examines the stolen belongings, she finds little of value at first. However, she discovers a hidden compartment in So-ran’s suitcase containing bullets. Instead of handing them to the authorities or asking questions, she sees another chance to make money.

Tae-woong and His Connection to Sato

Tae-woong is introduced as an interpreter who works closely with Inspector-General Sato. Known as Hideo within Sato’s family, he was once a Korean boy living on the streets before Sato took him in and raised him as his adopted son.

Sato presents himself as the man who rescued Tae-woong and gave him an education, including a place at Tokyo Imperial University. Yet Tae-woong remembers the darker side of their relationship. Sato once killed his friend to teach him a lesson about stealing.

This memory raises questions about Tae-woong’s loyalty. Although he appears to serve Sato faithfully, his past suggests that his feelings may be more complicated than he lets others see.

Ga-kyung and Tae-woong also have an immediate connection through their first encounter at the station. She has stolen his wallet, and he is determined to find the clever thief who escaped him.

So-ran’s Secret Mission

So-ran’s stolen bag contains more than ordinary belongings. She is secretly involved with the Gugukdan, also known as the National Salvation Corps, a group working toward Korean independence. Philip is part of the same network, despite appearing publicly as a journalist with a family life.

So-ran has spent 13 years seeking revenge for her daughter’s death. She blames Sato for killing her child and other Korean girls, making the inspector-general her personal target as well as an enemy of the resistance.

She works with Philip and other members of the group, including Suzuki and Han Chul-ryong, to plan an attack. Their discussions reveal the anger caused by colonial rule, including resentment over Japanese authorities taking white rice from local people.

Ga-kyung, however, remains unaware of the full political picture. After discovering the bullets, she visits a pawn shop to learn their value. She then uses that knowledge to demand money from So-ran in exchange for returning them.

A Dangerous Dinner Party

The main characters finally come together at Philip and So-ran’s home. Sato, Tae-woong, and other officials attend dinner, unaware that the gathering is connected to a plan to kill the inspector-general.

So-ran intends to use a gun during the meal, while Philip tries to maintain the appearance of a normal household. Their plan becomes more difficult when Japanese guards search the property for weapons. Sato also grows suspicious of So-ran’s background, putting the group at greater risk.

Ga-kyung arrives at the house hoping to exchange the bullets for money. She pretends to be a maid and takes advantage of the busy household to search for valuable items. During this attempt, she discovers So-ran’s American passport and steals it, giving her another possible route toward the future she wants.

Unfortunately for Ga-kyung, Tae-woong recognizes her as the pickpocket from the train station. He confronts her about his missing wallet, while she tries to deny what she has done. Their encounter adds another layer of tension to an already dangerous evening.

The Episode Ends With an Assassination Attempt

Just as the dinner appears to be moving forward, an unexpected visitor arrives with a cake ordered for dessert. The delivery man is armed and appears to be preparing to kill Sato.

Ga-kyung is asked to help bring the cake inside. Instead of making a clean escape, she finds herself caught in the assassin’s plan. The episode ends with her trying to warn Tae-woong that she is being held at gunpoint.

This final moment brings the different storylines together. Ga-kyung’s theft has placed her in the middle of a political assassination attempt, So-ran’s revenge plan is at risk, and Tae-woong must deal with a thief who may know more than she admits.

100 Days of Deception Episode 1 Ending Explained

The first episode ends before the assassination attempt is resolved. The armed delivery man creates a new threat at the dinner party, leaving Ga-kyung in immediate danger as she tries to alert Tae-woong.

The important detail is that Ga-kyung has entered the situation for selfish reasons. She wants money for the bullets and has no clear commitment to the independence movement. Yet her presence could change the outcome of So-ran’s plan.

So-ran is already struggling to balance her personal revenge with the need to protect her fellow resistance members. The arrival of another would-be assassin makes the situation even harder to control. It is also unclear whether the delivery man’s target is only Sato or whether he has a separate grievance against him.

Tae-woong’s position is equally complicated. He works for Sato, the man who raised him, but he carries painful memories of his childhood. His encounter with Ga-kyung may eventually force him to question where his loyalty belongs.

For now, the ending leaves three major questions unanswered: Will Ga-kyung escape the gunman? Will So-ran’s mission succeed? And will Tae-woong continue protecting Sato when the truth about his past becomes harder to ignore?

The Meaning and Origin of 100 Days of Deception

The Korean title of the series is 100일의 거짓말, which can be translated as 100 Days of Lies. The English title, 100 Days of Deception, points to the same central idea: people pretending to be someone they are not in order to survive, gain power, or achieve a goal.

The series is an original Korean historical spy romance, not a retelling of a specific historical person’s life. Its fictional characters operate against the real background of Japanese colonial rule in Korea. The story uses that setting to explore resistance, revenge, divided loyalties, and the personal cost of living under an oppressive government.

The idea of 100 days also suggests a limited period in which Ga-kyung must maintain her cover and complete a dangerous mission. Every lie could protect her identity, but every new connection could make it harder to leave without consequences.

Ga-kyung’s deception begins as a way to earn money. So-ran uses deception to pursue revenge and independence. Tae-woong’s identity is shaped by a family history that may not be what it seems. These different motives give the title meaning beyond simple undercover work.

What Works Well in Episode 1?

A Strong Historical Setting

The colonial-era setting gives the story more weight than a typical romantic spy drama. The conflict is not limited to personal rivalries; the characters are also living in a society shaped by occupation, inequality, and resistance.

Ga-kyung Is Not a Typical Heroine

Ga-kyung is clever, resourceful, and willing to take risks, but she is not introduced as a selfless hero. Money and escape are her priorities. This makes her an interesting character because her future choices may force her to decide whether survival is more important than helping others.

The Story Builds Toward a Tense Finale

The episode starts with small thefts and gradually reveals a much larger conflict. The stolen bag connects Ga-kyung to So-ran’s mission, while the missing wallet creates a reason for Tae-woong to pursue her. By the dinner scene, the different storylines meet in a dangerous situation.

The Characters Have Conflicting Loyalties

So-ran’s desire for revenge, Tae-woong’s troubled relationship with Sato, and Ga-kyung’s wish to escape all create room for future conflict. The characters are not simply divided into people who are good and people who are bad. Their personal histories shape the choices they make.

What Could Be Better?

The main weakness of the premiere is that it introduces many characters, secret identities, and political connections in a short period. Some viewers may find it difficult to keep track of who is working with whom, especially as the characters move between their public roles and hidden activities.

Ga-kyung’s language skills are another point that could use more explanation. She speaks English and Japanese despite her difficult upbringing, and the first episode does not fully show how she developed those abilities.

These questions do not ruin the opening episode, but the next chapters will need to give the characters more depth and make their motivations clearer. The story has plenty of tension; it will be stronger if it gives viewers enough time to understand the people caught in it.
