100 Days of Deception brings together historical espionage, forbidden romance, political intrigue and the constant threat of being caught in a lie. Set in 1932 Gyeongseong during Japan's colonial rule of Korea, the South Korean drama follows Lee Ga-kyeong, a gifted pickpocket who agrees to spend 100 days undercover inside the Japanese Government-General. Her mission becomes considerably more complicated when she encounters Kim Tae-woong, an elite interpreter whose family connections place him dangerously close to the very man her resistance network wants to eliminate. Naturally, falling for someone connected to your target is not exactly ideal career planning.
For viewers looking for more shows like 100 Days of Deception, the best alternatives combine secret identities, resistance movements, dangerous investigations, complicated relationships and characters forced to choose between personal happiness and a greater cause. From Korean historical dramas and wartime romances to international spy thrillers, these 23 series offer plenty to watch next.
Shows Like 100 Days of Deception
1. Mr. Sunshine (2018)
Mr. Sunshine is one of the strongest recommendations for anyone drawn to the historical setting and emotional stakes of 100 Days of Deception. The Korean drama follows Eugene Choi, a man who returns to Korea after growing up in America, as his life becomes intertwined with aristocrat Go Ae-shin and a network of people determined to protect their homeland.
Set during a turbulent period of Korean history, the series combines political conspiracies, resistance activities, personal loyalties and a romance shaped by circumstances beyond the characters' control. Its lavish period production also makes the historical setting feel lived-in rather than like an expensive collection of costumes.
The connection with 100 Days of Deception lies in its exploration of independence, sacrifice and love under colonial rule. If Ga-kyeong's dangerous double life appeals to you, Mr. Sunshine offers a similarly compelling look at people risking everything for a future they may never get to enjoy.
2. Gyeongseong Creature (2023)
Set in 1945, Gyeongseong Creature follows Jang Tae-sang, a wealthy businessman in colonial-era Gyeongseong, and Yoon Chae-ok, a skilled investigator searching for her missing mother. Their investigation leads them towards a mysterious facility where human lives have become part of a disturbing experiment.
Although the series leans more heavily into horror, action and science fiction, its historical backdrop makes it an interesting companion to 100 Days of Deception. Both dramas explore life under Japanese colonial rule, where powerful institutions conceal their activities and ordinary people face consequences for challenging those in charge.
Chae-ok's investigative skills and Tae-sang's talent for navigating dangerous situations also create a partnership built on mistrust, survival and gradually developing affection. The difference is that Gyeongseong Creature adds monstrous threats to an already hostile political environment. Apparently, corrupt authorities are not enough trouble on their own.
3. Bridal Mask (2012)
Bridal Mask, also known as Gaksital, follows Lee Kang-to, a Korean police officer working under Japanese colonial rule who becomes entangled in the struggle for independence. His circumstances change when he adopts the identity of a masked resistance fighter, placing him in direct conflict with the authorities he once served.
The series shares several major themes with 100 Days of Deception, particularly secret identities, undercover operations, shifting loyalties and the dangers of working close to an enemy. Both stories examine the compromises people make when survival clashes with personal convictions.
The romance and action also add emotional weight to the political conflict. Kang-to's double life creates difficult choices, while his relationships become increasingly complicated as the resistance movement gathers momentum. For viewers who enjoy the tension of Ga-kyeong's undercover assignment, this drama offers a more action-driven take on the same historical struggle.
4. Chicago Typewriter (2017)
Chicago Typewriter connects contemporary life with Korea's independence movement during the 1930s. The story follows a bestselling author, a ghostwriter and a veterinarian whose present-day lives gradually reveal connections to people who lived during the colonial period.
Unlike 100 Days of Deception, this drama moves between different timelines and incorporates supernatural elements. However, its historical storyline explores resistance fighters, dangerous missions, personal sacrifice and relationships complicated by the political circumstances of the time.
Its strongest similarity is the way romance and friendship become inseparable from the fight for freedom. Characters must confront the consequences of decisions made under pressure, while the mysteries surrounding their past lives provide another reason to keep watching.
If you appreciate the historical intrigue in 100 Days of Deception but would prefer something with a more reflective, occasionally whimsical approach, Chicago Typewriter is a worthwhile choice. It also proves that unresolved business from the past can be considerably more complicated than an unanswered text message.
5. Snowdrop (2021)
Snowdrop centres on Im Soo-ho, a graduate student who suddenly appears injured at a women's university dormitory in Seoul. Eun Yeong-ro, a student who helps him, soon finds herself caught up in a dangerous political situation that threatens her relationships and her understanding of the people around her.
Set against the political tensions of 1987 South Korea, the series differs from 100 Days of Deception in both its historical period and central conflict. Nevertheless, the two dramas share a powerful combination of concealed identities, political intrigue, surveillance and romance complicated by conflicting loyalties.
The relationship between the central characters becomes increasingly difficult as the truth surrounding Soo-ho emerges. That tension will appeal to viewers who enjoy romances in which trust must be earned rather than handed over after one meaningful glance.
Snowdrop is particularly suitable for anyone who wants a relationship-driven thriller in which personal feelings and political realities continually collide.
6. The Red Sleeve (2021)
The Red Sleeve follows court lady Seong Deok-im and Crown Prince Yi San, whose relationship develops within the rigid hierarchy of the Joseon royal court. Their growing affection is complicated by royal expectations, political responsibilities and Deok-im's desire to retain control over her own life.
The series places greater emphasis on romance and court politics than espionage, but its central conflict will feel familiar to fans of 100 Days of Deception. Both dramas feature characters who cannot simply follow their hearts without considering the wider consequences.
Deok-im must navigate a world where seemingly minor decisions can affect her future, while Yi San faces the burden of his position. Their relationship is shaped by the imbalance of power between them, creating emotional tension without relying on a conventional romantic formula.
For viewers who enjoy the impossible-romance element of 100 Days of Deception, this historical drama offers a more intimate alternative. There are fewer undercover missions, but the royal court has more than enough rules to make everyone's life unnecessarily difficult.
7. The Princess's Man (2011)
The Princess's Man is a historical romance set during the Joseon dynasty, following the relationship between Kim Seung-yoo and Princess Se-ryung. Their feelings develop as political rivalries and a violent struggle for power threaten to tear their families apart.
Its setting predates the colonial period featured in 100 Days of Deception, but the underlying themes are closely related. Both dramas explore how political conflict can transform personal relationships, forcing characters to reconsider their loyalties and the futures they once imagined.
The series also combines palace intrigue with a romance that becomes increasingly difficult as circumstances change. Rather than placing its protagonists inside an espionage operation, it puts them at the centre of a political conflict in which family connections can be as dangerous as any secret mission.
If you enjoy stories in which love becomes complicated by powerful enemies and competing obligations, The Princess's Man deserves a place on your watchlist.
8. My Dearest (2023)
My Dearest follows Lee Jang-hyun, a mysterious man with a complicated past, and Yoo Gil-chae, a noblewoman whose life changes dramatically during the Qing invasion of Joseon. Their relationship unfolds against a backdrop of war, displacement and the struggle to survive.
The drama shares 100 Days of Deception's interest in romance under extreme pressure. Its characters must navigate political upheaval and shifting circumstances while trying to preserve their sense of identity and their connections with other people.
Although the historical events are different, both stories explore how individuals adapt when the world around them becomes increasingly hostile. Personal ambitions give way to urgent decisions, and affection becomes harder to express when survival takes priority.
My Dearest is a particularly good choice for viewers who want a sweeping period romance with substantial historical context. It offers a more expansive war narrative than 100 Days of Deception, but the emotional conflict remains rooted in the same question: what happens to love when history refuses to cooperate?
9. Captivating the King (2024)
Captivating the King centres on Yi In, a Joseon monarch caught in political rivalries, and Kang Hee-soo, a talented baduk player who approaches him under concealed intentions. Their relationship develops within a world of court manoeuvring, deception and competing ambitions.
The similarities to 100 Days of Deception are especially clear in the use of hidden motives and romance as part of a larger political game. Hee-soo does not enter the royal court with straightforward intentions, and the truth behind her actions complicates her growing feelings for the king.
Both dramas feature characters who must constantly assess the people around them, knowing that misplaced trust could have serious consequences. The historical settings differ, but the pressure created by secrets and political loyalties remains remarkably similar.
For anyone who enjoys watching intelligent protagonists attempt to stay several steps ahead of their opponents, Captivating the King offers plenty of intrigue. Its romantic tension also makes it an appealing choice when the espionage in 100 Days of Deception is only half the attraction.
10. The Tale of Nokdu (2019)
The Tale of Nokdu follows Jeon Nok-du, a young man who disguises himself as a woman and enters a village inhabited by widows while investigating a mystery involving his family. His unusual cover leads him into unexpected relationships and a wider political conflict.
Its tone is lighter than that of 100 Days of Deception, but the central use of disguise makes it an obvious recommendation. Nok-du's assumed identity creates opportunities for comedy and romance, while the secrets surrounding his mission gradually draw him deeper into the political landscape.
Both series feature protagonists whose survival depends on convincing other people that they are someone else. The difference is that Nok-du's disguise creates plenty of awkward situations, whereas Ga-kyeong's undercover work carries far more immediate danger.
For viewers who appreciate elaborate cover stories but need a break from relentless tension, The Tale of Nokdu offers a refreshing historical adventure with romantic complications and political intrigue.
11. The Crowned Clown (2019)
The Crowned Clown follows Ha Seon, a clown who resembles the Joseon king so closely that he is recruited to take the monarch's place amid a dangerous political crisis. What begins as an impersonation gradually becomes a test of his judgement, loyalty and ability to survive at court.
The premise shares a clear connection with 100 Days of Deception: an ordinary person adopts another identity and enters a powerful institution where one mistake could expose everything. Both stories use deception as a survival strategy, while exploring the emotional cost of pretending to be someone else.
Ha Seon must learn court etiquette, navigate rival factions and manage relationships under increasingly difficult circumstances. His experience makes the series especially appealing to viewers who enjoy seeing an outsider enter an unfamiliar world and discover that the real danger comes from the people already inside it.
The romantic storyline adds another layer to the impersonation plot, making this a strong option for fans of historical thrillers with emotional stakes.
12. Under the Queen's Umbrella (2022)
Under the Queen's Umbrella follows Queen Im Hwa-ryeong as she attempts to protect her sons and secure their futures within a royal court filled with political rivalries. Her efforts become increasingly complicated as competing factions attempt to influence the succession.
Unlike 100 Days of Deception, the series is not built around a covert spy mission. Instead, it examines how political power operates behind the formal appearance of royal life. Secrets, manipulation and carefully calculated decisions drive the story forward.
The connection lies in its depiction of institutions where appearances matter and trust is difficult to establish. Just as Ga-kyeong must conceal her true purpose inside the colonial administration, Hwa-ryeong must manoeuvre through court politics without allowing her opponents to dictate the outcome.
The series is ideal for viewers who enjoy strategic characters and tense political confrontations. Its family-centred perspective also offers a different way to explore the cost of ambition, loyalty and survival in a rigid hierarchy.
13. Pachinko (2022)
Pachinko follows several generations of a Korean family whose lives are shaped by migration, discrimination, economic hardship and the consequences of Japan's colonial rule. Beginning in the early twentieth century, the story follows Sunja and her descendants as they navigate changing circumstances across Korea and Japan.
The series shares the historical context of 100 Days of Deception, particularly its exploration of Korean identity under Japanese rule. However, its focus is broader, examining the long-term effects of historical and political forces on ordinary people rather than centring on a single undercover mission.
Both productions explore what it means to protect one's future when the surrounding system offers limited freedom. Their characters must make difficult choices about loyalty, ambition and belonging, often with consequences that extend far beyond their immediate circumstances.
Pachinko is a compelling choice for viewers who want a more expansive historical drama. Its multigenerational structure provides a different perspective on the era, demonstrating that history does not end when one dangerous mission is complete.
14. Empress Ki (2013)
Empress Ki follows a woman of Goryeo origin who rises to power within the Yuan imperial court. Her journey involves political manoeuvring, personal ambition, complicated relationships and the struggle to retain influence in an environment dominated by powerful rivals.
The drama is considerably more expansive than 100 Days of Deception, but its emphasis on a resourceful female protagonist makes it a strong match. Both stories follow women who must learn to navigate hostile institutions, conceal their intentions and use their intelligence to survive.
Where Ga-kyeong's mission has a defined 100-day deadline, the protagonist of Empress Ki faces a longer and more complex struggle for power. Her relationships are deeply affected by political realities, and romantic feelings rarely exist independently of questions about loyalty and ambition.
For fans of historical intrigue, this series offers a substantial commitment with plenty of shifting alliances. It is also a reminder that entering a powerful court is difficult enough without everyone treating affection as a potential political weapon.
15. Six Flying Dragons (2015)
Six Flying Dragons dramatises the political struggles surrounding the foundation of the Joseon dynasty. It follows several influential figures as they pursue competing visions for the future of Korea, with political schemes, military conflict and personal rivalries shaping their decisions.
The series places less emphasis on romance than 100 Days of Deception, but it shares an interest in political transformation and the people willing to take considerable risks to achieve their goals. Its characters operate in a world where loyalty can change quickly and personal ambition has consequences for an entire nation.
Viewers drawn to the resistance network and political stakes in 100 Days of Deception may appreciate the way Six Flying Dragons examines the origins of a new political order. The historical period is different, but the questions surrounding power, justice and sacrifice remain relevant.
This is the choice for viewers who want a detailed historical epic rather than a tightly focused spy romance.
16. The Nokdu Flower (2019)
The Nokdu Flower is set during the Donghak Peasant Revolution of 1894 and follows two half-brothers whose lives take different directions as social unrest spreads across Korea. Their opposing circumstances place them on different sides of a conflict shaped by inequality, political instability and the desire for change.
The connection with 100 Days of Deception lies in the portrayal of resistance and the human consequences of political upheaval. Both dramas explore a society under pressure, where individuals are forced to make decisions that can separate them from their families and former lives.
While The Nokdu Flower focuses on a historical uprising rather than a covert operation, its political conflicts provide a similar sense of danger and uncertainty. The characters' personal relationships are continually tested by the wider struggle around them.
It is a strong option for viewers who want more historical context alongside action and emotional drama. The series also offers a useful reminder that political movements are rarely as simple as choosing a side and expecting everything to work out neatly.
17. Alchemy of Souls (2022)
Alchemy of Souls follows a powerful assassin whose soul becomes trapped in another woman's body, leading to an unusual partnership with a young nobleman who wants to change his destiny. Their relationship develops amid magical training, secret identities and political rivalries.
The fantasy setting makes it a more distant match for 100 Days of Deception, yet both dramas rely on concealed identities and characters who must keep important truths hidden. The central relationship is complicated by secrets, ambitions and the risk of being exposed.
The series also features protagonists whose skills and motivations are not always what they appear to be. Their changing relationship provides emotional momentum while a larger political conflict develops around them.
If you enjoy the combination of romance, intrigue and dangerous secrets but are happy to trade historical espionage for magic, Alchemy of Souls is a strong alternative. It delivers plenty of twists without requiring you to memorise the organisational chart of a colonial government.
18. The King: Eternal Monarch (2020)
The King: Eternal Monarch follows a Korean emperor who discovers a passage between parallel worlds and meets a detective from an alternate version of Korea. Their growing relationship becomes entangled in a conspiracy involving political power, family history and the stability of both worlds.
Its contemporary fantasy premise differs substantially from 100 Days of Deception, but the two series share an interest in hidden truths and relationships complicated by political responsibilities. The characters must question appearances, investigate concealed motives and decide how much they can trust one another.
The emperor's position also creates a persistent tension between private feelings and public obligations. Like the central relationship in 100 Days of Deception, the romance cannot be separated from the wider forces influencing the characters' lives.
This series is worth considering if you want a more elaborate mystery with romantic elements. It replaces colonial-era espionage with parallel universes, which is certainly one way to make an already complicated relationship even harder to explain.
19. The K2 (2016)
The K2 follows Kim Je-ha, a former soldier who becomes a bodyguard for a powerful political family. His work draws him into a world of corporate interests, political ambition, personal secrets and dangerous rivalries.
Among contemporary Korean thrillers, this is one of the more direct matches for the action and conspiracy elements of 100 Days of Deception. Both stories feature protagonists operating close to influential figures while navigating threats that extend beyond their official duties.
The romance is less central to the action than it is in some historical dramas, but relationships still complicate the characters' choices. Je-ha must determine who deserves his loyalty as the political situation around him becomes increasingly difficult to control.
For viewers who enjoy undercover tension, elaborate schemes and action-driven storytelling, The K2 offers a modern alternative. Its political setting is different, but the basic problem remains the same: working for powerful people is rarely a sensible career choice when nobody tells you the full story.
20. Healer (2014)
Healer follows a mysterious courier known as Healer, who accepts dangerous assignments while keeping his real identity hidden. A new investigation brings him into contact with journalist Chae Young-shin and reporter Kim Moon-ho, gradually uncovering connections between their lives and a long-buried political scandal.
The series is a strong recommendation for fans of 100 Days of Deception because it combines secret identities, investigative work, conspiracy and romance. Its protagonist operates in the shadows, while the journalists attempt to uncover truths that powerful people would prefer to keep buried.
Both dramas use suspense to test relationships and challenge the characters' assumptions about those around them. Their central figures also rely on specialised skills to navigate situations where a wrong move can expose their secrets.
Although Healer takes place in a modern setting, its balance of action, mystery and romance makes it one of the most accessible alternatives on this list. It is particularly appealing if you want a thrilling investigation with a relationship that develops alongside the central mystery.
21. The Veil (2021)
The Veil centres on Han Ji-hyuk, an elite National Intelligence Service agent who returns after disappearing during a mission. As he attempts to uncover what happened, he becomes involved in a web of internal betrayal, covert operations and dangerous secrets.
Of all the contemporary series on this list, The Veil is one of the closest matches for the espionage mechanics of 100 Days of Deception. Both dramas place their characters in environments where information is valuable, loyalties are uncertain and a person's apparent role may conceal a different objective.
The major difference is the romantic emphasis. 100 Days of Deception combines its spy narrative with a central love story, whereas The Veil concentrates more heavily on intelligence work and the consequences of betrayal.
If the undercover mission is your favourite part of 100 Days of Deception, this series should be high on your list. It delivers a more grounded intelligence thriller in which knowing whom to trust is just as important as knowing where the next threat will come from.
22. My Name (2021)
My Name follows Yoon Ji-woo, a young woman who joins a criminal organisation and enters the police force undercover while searching for answers about her father's death. Her assignment forces her to maintain a dangerous double life as she becomes increasingly entangled in violence, loyalty and betrayal.
The series differs from 100 Days of Deception in its modern setting and much darker action-driven tone. However, its central premise is strikingly similar: a protagonist adopts a concealed identity, enters an organisation connected to a personal mission and must constantly manage the risk of exposure.
Both dramas also explore the emotional consequences of deception. Their characters become increasingly isolated as their public roles clash with their private objectives, making trust a difficult thing to establish.
My Name is a particularly good choice for viewers who want a more intense undercover thriller. The romantic elements are less prominent, but the suspense and personal stakes make it a compelling follow-up for anyone who enjoys watching a carefully planned mission spiral into something far more complicated.
23. The Story of Park's Marriage Contract (2023)
The Story of Park's Marriage Contract follows Park Yeon-woo, a woman from nineteenth-century Joseon who unexpectedly finds herself in modern-day South Korea. Her encounter with Kang Tae-ha leads to a contractual marriage that gradually becomes entangled in family secrets, personal history and unexpected feelings.
The series takes a lighter approach to historical romance than 100 Days of Deception, and it does not revolve around an undercover espionage mission. Nevertheless, it shares the use of concealed intentions, unusual identities and a relationship that develops under circumstances neither protagonist can entirely control.
Its combination of historical and contemporary settings also provides an interesting contrast with the colonial-era world of 100 Days of Deception. Rather than following a spy into enemy territory, it places a historical protagonist in a society she barely understands and asks her to navigate its rules.
For viewers who want romance and secrets without another relentless political thriller, this is a welcome alternative. It offers a lighter finish to the list while retaining the central appeal of watching two people discover that their carefully arranged plans may not survive contact with genuine feelings.
What makes 100 Days of Deception such an appealing premise is the way it combines several genres without making any one of them feel unnecessary. The historical setting provides genuine stakes, the undercover mission creates a ticking clock, and the romance introduces another problem for a protagonist who already has enough reasons to lose sleep. Falling for someone connected to your target is hardly the ideal way to keep an operation running smoothly.
For me, Mr. Sunshine, Bridal Mask and Chicago Typewriter are among the strongest starting points because they combine Korean history with resistance, personal sacrifice and relationships shaped by political circumstances. Healer and The Veil are better options if espionage and secret identities matter more to you than the period setting. Meanwhile, My Dearest and The Red Sleeve are worth prioritising if emotional storytelling is the main attraction.
Ultimately, the best alternative depends on what you enjoyed most about 100 Days of Deception. Do you prefer the undercover suspense, the historical backdrop, the impossible romance or the constant suspicion that somebody is hiding something? Tell us which series you would watch first, and share any other dramas you think deserve a place on this list.
