Premiering its first season in late 2023, the drama quickly became a global phenomenon, captivating audiences with its dark premise, stellar cast, and compelling backdrop.

The Dark World of Gyeongseong in 1945

The series is set in the spring of 1945, a tumultuous and significant period in Korean history. The title itself is a historical marker: Gyeongseong is the old name for Seoul, given by the Imperial Japanese government during their colonial rule of Korea (1910–1945).

The drama immerses viewers in a vivid, yet oppressive, atmosphere of the city’s darkest era, where the glamour of the capital’s streets hides a terrifying secret. The premise focuses on the grim realities of this period, exploring themes of survival, human greed, and the fight for independence, all intertwined with a fictional, monstrous horror.

Historical Inspiration and Fictional Horror

The core of the horror element is rooted in a dark chapter of history. The show’s plot, which centers on secret biological experiments conducted at the mysterious Ongseong Hospital, is heavily inspired by the real-life Unit 731. Unit 731 was a covert Japanese military unit that performed biological and chemical warfare experiments on living humans—primarily Chinese, Korean, and Soviet prisoners—during World War II.

By using this historical context as a foundation, Gyeongseong Creature elevates its monster narrative into a powerful allegory. The creature that is born from these experiments is not merely a monster of fantasy, but a physical manifestation of the brutality, unethical ambition, and cruelty of the colonial regime.

Star Power: Park Seo-joon and Han So-hee

A significant factor in the series’ global anticipation was the casting of two of South Korea’s most popular A-list actors, each transitioning into a more action-oriented role for the project.

Park Seo-joon as Jang Tae-sang

Park Seo-joon stars as Jang Tae-sang, a wealthy and influential pawnshop owner of the House of Golden Treasure (Geumokdang) in Bukchon. Known as the most reliable source for information in Gyeongseong, Jang Tae-sang is introduced as a character whose immediate priority is survival and maintaining his comfortable status.

• Jang Tae-sang’s Journey: His life of pragmatic neutrality is abruptly challenged when he is forced to investigate a string of mysterious missing person cases, pushing him to re-evaluate his values and confront a much deeper sense of justice.
• Previous Acclaim: Park Seo-joon is widely known as the “king of romantic comedy” for his lead roles in global hits like What’s Wrong with Secretary Kim? (2018), Itaewon Class (2020), and Fight for My Way (2017). He also made his Hollywood debut in the Marvel Cinematic Universe film The Marvels (2023).

Han So-hee as Yoon Chae-ok

Han So-hee plays Yoon Chae-ok, a highly skilled todu-gun (a person who finds missing people) who travels the world with her father. She is introduced in Gyeongseong while desperately searching for her mother, who went missing a decade earlier.

• Yoon Chae-ok’s Skills: Having lived a difficult life traveling through Manchuria and Shanghai, Yoon Chae-ok is an expert in survival, capable of handling weapons, knives, and machinery. Her fierce determination and action prowess are a central focus of her character.
• Previous Acclaim: Han So-hee’s breakthrough came with The World of the Married (2020), and she cemented her versatile acting range with the gritty action thriller My Name (2021) and the romantic drama Nevertheless (2021).

A Fusion of Genres: Horror, History, and Thriller

Gyeongseong Creature is characterized by its successful merging of disparate genres, creating a unique viewing experience:

• Historical Drama: The series provides a lush, meticulously crafted backdrop of Gyeongseong’s 1940s colonial architecture, fashion, and social tensions.
• Creature Horror: The monster itself is central to the plot, serving as the terrifying focal point of the hospital’s dark secret. The show features a high-stakes battle for survival against this horrific being.
• Mystery/Thriller: The main narrative drive is a classic whodunit, as Jang Tae-sang and Yoon Chae-ok follow clues through a series of disappearances, leading them closer to the horrifying truth inside Ongseong Hospital.

Production and Release Structure

The series was developed with a substantial budget, estimated to be around 70 billion Korean won (approximately $53 million USD), positioning it as one of Netflix’s most expensive Korean originals.

The 10-episode first season was released on Netflix in two distinct parts:

• Part 1: Released on December 22, 2023 (Episodes 1–7).
• Part 2: Released on January 5, 2024 (Episodes 8–10).

Following its debut, the series achieved significant international success, ranking high on Netflix’s Global Top 10 for non-English television titles in numerous countries.

The Second Season: A Jump to the Present

In an unusual move for a period drama, Season 2 shifts the narrative drastically. Released on September 27, 2024, the second season is set 79 years after the first, moving to present-day Seoul. The plot follows a man named Ho-jae, who bears a striking resemblance to Jang Tae-sang, as he crosses paths with Yoon Chae-ok, continuing the exploration of the original story’s unresolved fate and evil relationships. This time jump allowed the director to incorporate audience feedback and deliver a faster-paced, more action-centric story than its predecessor.
