100 Days of Deception Episode 5

Gakyeong enters the real Jongno Police Station, where interpreting becomes an ordeal. Episode 5 exposes the violence behind Japan’s carefully managed image of colonial Korea.

Spoiler warning: This post covers the main plot and final scene of 100 Days of Deception Episode 5.

Lee Gakyeong (Lee Ga-kyeong) comes face to face with the brutality of Japanese colonial rule. In Episode 4, she saw through a fake Jongno Police Station. This time, she walks into the real one. There, she can’t wait for the act to end, and she can’t lie her way out.

100 Days of Deception Episode 5 Recap: Real Terror Beyond the Fake Interrogation Room

Hideo at the Door, Gunfire in Dongsung-dong

When Gakyeong comes out after calling Philip Yoo in English, Hideo, Sato’s adopted son, is standing at the door. He says he forgot he is supposed to treat her like royalty and offers to take her to a photo studio. How much of the call he overheard is never revealed.

Meanwhile, in Dongsung-dong near Keijo Imperial University (Keijo was the Japanese name for Gyeongseong), Gugukdan member Han Cheolyong (Han Cheol-yong) takes aim at Sato’s car. But instead of Sato, inside sits Jang Jeongyeop (Jang Jeong-yeop), a Gugukdan independence fighter, gagged and bound. The moment Cheolyong hesitates, shots come from inside the car. It was a trap. While Yoo Soran (Yoo So-ran) provides cover from the second floor of a fabric shop, herbal doctor Gwak Unhak (Gwak Un-hak) and Lee Yeongbok (Lee Yeong-bok), both masked, drive in and pull Jeongyeop out. But Jeongyeop dies in the car. Soran’s bullet grazes Fukuda’s cheek, and Soran is shot in the arm.

When Fukuda and his officers storm the fabric shop, Yeongbok tells them a masked man ran outside. He himself has been shot in the stomach. In the fitting room, Kim Myeongnam (Kim Myeong-nam), daughter of the president of Joil Textiles, is changing clothes, and Soran is hidden farther inside the fitting room. Yeongbok hands over his business card, mentions that the company president is about to dine with the Governor-General, and gets through the moment. As soon as Fukuda leaves, Yeongbok collapses.

Under the Black Cloth at the Photo Studio

At the photo studio, Gakyeong hears the voice of Noma, who has come to deliver seolleongtang, a Korean beef bone soup. She longs to see Noma and Kkotnim, but she can’t. She hides in a hurry, and Hideo asks if Noma is an old boyfriend. Gakyeong storms out of the studio angry. Then she hides in an alley, watching Noma and Kkotnim and missing them.

Philip Identifies a Fallen Comrade, Hideo Cares for Kkotnim

At the scene of the shootout, Philip lifts a white sheet and confirms Cheolyong is dead. The police drag away even innocent bystanders, and Noma, who was out on a delivery, is arrested too. Soran’s husband, Geum Seokjung (Geum Seok-jung), is hiding somewhere, being treated for a gunshot wound.

While Noma is in custody, Hideo finds Kkotnim alone, carries her on his back, and takes her home to her shack in the shantytown. Noma arrives later, frantically calling her name. After Hideo leaves, Kkotnim tells Noma that Hideo has promised to teach her to read.

Meanwhile, while clearing out Cheolyong’s room, Soran and Philip find a letter he left behind. It shows he was ready to die for Korea’s independence. At the same time, Jeongyeop’s wife identifies her husband’s body and breaks down sobbing.

Hierarchy at the Government-General, and Fukuda’s Insults

Sato, the Administrative Superintendent, greets the Governor-General at the train station. The Governor-General says he has had to keep his schedule secret because of people like Lee Bong-chang, the independence activist who threw a grenade at the Japanese king’s procession in Tokyo that January. He adds that futei senjin—“seditious Koreans,” a derogatory colonial label for Koreans who resisted Japanese rule—have been running wild since Sato took office.

The Governor-General’s office. The Governor-General, Sato, and the army commander are there. The Governor-General orders Sato to tighten security in Gyeongseong and keep the foreign press under control until the League of Nations commission arrives. After Sato leaves, the army commander says Sato is a Japanese settler in Korea, an inferior “outsider” to be watched, and the Governor-General agrees. Outside the door, Sato hears every word.

At the Government-General, Gakyeong runs into Fukuda. He asks after Philip, then says that Korean women are boring, but a woman taught by an American must be different. When Hideo steps in and sends Gakyeong away, Fukuda sneers that the two “Chosenjin” make an amusing picture, using a Japanese slur for Koreans. Soon, Gakyeong is ordered out on an assignment. Waiting in the car is Fukuda.

Gakyeong Enters the Real Jongno Police Station

Fukuda takes her to the Jongno Police Station. Screams echo down the corridor. Fukuda says the man inside won’t talk because he doesn’t know the “national language,” so he has brought Gakyeong to interpret. Here, the “national language” means Japanese. In a room lined with torture devices, the man being held is Geum Seokjung. His gunshot wound has festered, and he is burning with fever.

The officers douse him with water and beat him whenever he fails to answer. Fukuda makes Gakyeong translate everything, from “Ask his name” to every curse he spits. Dying miserably, that’s what Korean independence is. You Korean cockroaches. Fukuda smiles as he watches her shake with fear.

At that same hour, Hideo is teaching Kkotnim to read. His face is full of worry.

Geum Seokjung Reacts to the Name Geum Seohui

The moment Fukuda calls Gakyeong “interpreter Geum Seohui,” Seokjung finally speaks. In Korean. Aren’t you the live-in maid from that house? Why are you using that name? While Fukuda demands to know what he said, Hideo walks in.

When Hideo sarcastically asks whether Fukuda has learned much now that he has borrowed an interpreter from the Government-General, Fukuda slaps him. You think you’re really the Superintendent’s son? Then he sees Sato standing behind him.

Sato says to Fukuda, “If Hideo isn’t my real son, then what is he?” Fukuda presses his head to the floor. Sato tells Hideo, “See her home, Interpreter Sato.”

What Sato Objects To Is Foreign Press Coverage

Once Gakyeong leaves, Sato slaps Fukuda. Has he forgotten she is Philip’s woman? Doesn’t he know that the events of Taisho 8 blew up because an American reported them abroad?

Outside, it is raining. Hideo apologizes to Gakyeong, but he also asks her to make sure Philip keeps today out of the foreign press.

At the station, the torture continues. With Sato watching, Fukuda shows Seokjung his comrade Na Byeongsun (Na Byeong-sun), hung upside down, and threatens to bring in Seokjung’s family and kill them before his eyes. My family? Seokjung laughs through his tears. Even as the beating goes on, the laughter doesn’t stop.

Gakyeong Wants Out

Back home, Gakyeong packs her bags. She had gone to the Jongno station worried that Soran had been caught, she says, and ended up spending the whole day translating insults hurled at an independence activist. When she says she doesn’t want to die a dog’s death in this insanity, Philip steps in. No Korean thinks of it as a dog’s death, he says.

When Gakyeong says the man she interpreted for was Geum Seokjung, and that he reacted to the name Geum Seohui as if he would tear her apart, Soran’s eyes fill with tears. Gakyeong realizes that he is Soran’s husband, the father of her dead daughter, Geum Seohui. “You’re all insane. All this—for independence?”

Shaking off Soran, who warns that traitors will be executed, Gakyeong walks out into the rain. She falls, and her bags spill across the road. Out in the rain, Philip calls her “Geum Seohui.” Gakyeong says she doesn’t know anyone by that name. Behind Philip’s back is a pistol.

Why Did Japan Fear the Foreign Press?

Sato slaps Fukuda not because of Gakyeong, but because of Philip. They were in the same interrogation room, yet Seokjung stays at the station, while Gakyeong, connected to a foreign reporter, walks out. At the time, the League of Nations was investigating Japan’s invasion of Manchuria. The Lytton Commission rejected both Japan’s claim of self-defense and its claim that Manchukuo was founded by the free will of its people. The peaceful Korea the Governor-General talks about is the picture Japan wanted to show the world.

Taisho 8, which Sato mentions, is 1919, the year of the March 1st Independence Movement. Albert Taylor, an American businessman and temporary correspondent for the Associated Press, reported the movement and the Jeam-ri massacre to the world. On April 15 that year, Japanese troops locked villagers in a church in what is now Hwaseong, Gyeonggi Province, shot them, and set the church on fire. The lesson Sato draws from that history is not “never do that again.” It is “don’t let it get out.”

That is why, when Hideo asks her on the rainy street to keep the story out of the foreign press, Gakyeong understands what comes attached to the protection she received. It is a demand that she never speak of what she saw.

How Did Japanese Colonial Authorities Torture Independence Activists?

Japanese police and soldiers used beatings, water torture, and confinement in cramped boxes against independence activists and ordinary Koreans alike. The goal was to extract comrades’ names and break the will to resist. Confessions forced under torture were also used to fabricate cases.

It is too horrific to put into words. If you visit Korea, I’d recommend a trip to the Independence Hall of Korea in Cheonan, South Chungcheong Province. The records of people who actually endured the suffering the actors portray are kept there.

Did Japan Discriminate Even Against Japanese Living in Its Colonies?

Japan called its home islands naichi, the “inner lands,” and its colonies such as Korea and Taiwan gaichi, the “outer lands.” The distinction was more than a label. Under the Universal Manhood Suffrage Law of 1925, eligible men living in Japan proper could vote in elections to the House of Representatives. A Japanese man who moved to Korea lost that vote. Conversely, a Korean man living in Japan proper could vote. For these elections, living in Japan proper was a condition of eligibility, including for Korean men.

Sato is the Administrative Superintendent, the second-highest official in Korea. Yet to the army commander, a member of the home-island elite, he is just a Japanese settler in a colony, an inferior outsider. Of course, Japanese settlers in Korea remained legally Japanese, and what they faced was nothing like the discrimination Koreans suffered. Still, seen from Tokyo, they ranked a step lower.

Episode 5 shows this hierarchy layer by layer. The army commander looks down on Sato. Fukuda presses his head to the floor before Sato, yet slaps Sato’s adopted son Hideo and insults him with the same anti-Korean slur. That is why Sato’s line, “If Hideo isn’t my real son, then what is he?” lands so heavily. He is the same man who just heard contempt aimed at himself through a closed door. I read his words as protecting Hideo and, at the same time, protecting his own position. When his adopted son is demeaned with an anti-Korean slur, Sato’s own authority is being challenged too.

Why Did Gakyeong Break After Translating Fukuda’s Words?

Gakyeong never lays a hand on Seokjung. But every insult that reaches him passes through her voice. As a fellow Korean, she has to tell the man in front of her that he will die a dog’s death, alone. In Episode 4’s fake interrogation room, she saw through the act and escaped. Against real torture, that talent is useless.

In Episode 3, Gakyeong became a spy to get to America. That goal hasn’t changed. What has changed is that she now knows the price of the job. On top of the fear that she could be caught, there is the anguish of having to keep standing where others are crushed. “All this—for independence?” carries both.

Why Has the Name Geum Seohui Become Dangerous for Gakyeong?

Seokjung, who stayed silent through torture, reacts to the name Geum Seohui. To the Japanese police, it is an interpreter’s name. To him, it is the name of his dead daughter. The name Gakyeong uses at the Government-General, the daughter Soran lost, and Seokjung under torture all become one family’s story.

She thought the false name would protect her, but too many stories she knows nothing about are attached to it. Fukuda has already begun to suspect it. At the end, Gakyeong says she doesn’t know anyone by that name, but behind Philip, who calls her by it, is a gun. Whether she can now set down a name she took on to get to America is anything but certain.
