100 Days of Deception: Understanding Its Divided City

Category: K-Content & Fandom Culture

A pickpocket wants her freedom. Her assignment takes her inside the Japanese colonial government, where she falls for her target's son. That is the official setup of 100 Days of Deception (100일의 거짓말), an espionage-romance premise in which entering an institution and becoming emotionally involved pose different risks. Official synopsis, Netflix.

Gyeongseong is the colonial-era city now known as Seoul. The Seoul Museum of History's drama collaboration places the story in 1930s Seoul. This spoiler-light primer explains that setting without discussing episode outcomes.

How Gyeongseong's urban divide changed

The official companion's museum-sourced history uses Cheonggyecheon as a reference: Bukchon lay north of the stream, Namchon south. Japanese settlement developed around the Chungmuro and Namdaemun-ro intersection in the south. Here, Bukchon means a broad historical area, not simply today's tourist hanok village.

The guide attributes the south's improved infrastructure to economic advantage and unequal administrative investment. Meanwhile, displaced Koreans increased population density in the north, worsening housing conditions.

Then the picture changes. From the mid-1920s, government offices, city hall and upscale housing entered the north, and Japanese settlement spread northward. The north/south contrast used by the drama's companion therefore should not become a permanent ethnic border in the viewer's mind.

For a viewer drawn to the romance, the premise suggests a useful tension: the pickpocket enters a government institution for freedom, while falling for her target's son adds a personal attachment to that mission. Ask what belonging would cost her. This is an interpretive question, not an episode finding.

If historical context is your main interest, carry the changing boundary with you: a character's location alone need not settle their position within the city.

What the current Netflix page lists

Netflix's October release announcement, dated September 30, listed the series for October 10. As checked on October 13, its public Korean-market title page lists the first two episodes, plus Korean original audio, Korean audio description, and English and Korean subtitles.

That is a snapshot of one market's catalog, not a global availability promise or a playback test. If you prefer a finished-season binge, two episode listings do not establish that the whole season is ready.
