Across the heavily fortified border dividing the Korean Peninsula, a quiet cultural revolution has been unfolding: forbidden South Korean K-pop has slipped past state censorship, reshaping how generations of North Koreans see the world, and in many cases, pushing them to risk everything for a life of personal freedom. For defectors who have settled in the South, this music has done more than entertain—it has helped them heal, build new identities, and embrace the autonomy they were denied for decades.
Lee Yeon-su, a North Korean defector who fled to South Korea in 2011, knows this transformation firsthand. On a warm Saturday in June, she traveled from Seoul to Busan to attend her third BTS concert in three months, chasing a sense of joy she once never could have imagined. After a distant view at the group’s Seoul comeback concert in March and a rain-soaked opening tour stop in April that drowned out the music, the Busan show lived up to every expectation. “Every time I come to a BTS concert, I realise how happy I am that I can like and support someone of my own free will,” she said, asking to keep her real name private to protect family still in North Korea. “That would have been unimaginable in North Korea.”
Born and raised in the closed authoritarian state, Lee grew up cut off from all outside media, where access to public events required state approval and the regime maintained strict control over every aspect of daily life through surveillance and ideological loyalty requirements. “You had to be selected to attend events and if you weren’t, you had to stay home with your curtains closed,” she recalled. Raised in a military family that was taught to view South Korea as an enemy, she avoided South Korean culture after first escaping—but music eventually found its way to her. Today, screaming, jumping, and singing along to high-energy BTS hits like *Fire* and *Mic Drop* alongside thousands of other fans is more than a hobby: it is a celebration of the personal choice she was denied for most of her life.
Today, accessing or sharing South Korean media remains a serious criminal offense in North Korea, punishable by imprisonment, labor camp detention, and even execution. Yet interviews with multiple defectors published by the BBC reveal that K-pop has quietly permeated daily life across the country, spreading through hidden SD cards, smuggled MP3 players, and illegally accessed cross-border TV signals. Young people have embraced the music so thoroughly that references to the global supergroup BTS (known as Bangtan Sonyeondan in Korean) have even entered coded everyday slang, with defectors reporting phrases like “Have you tried on a Bangtan vest?” used to discuss contraband South Korean goods.
For many North Koreans, the first encounter with K-pop is a jarring, eye-opening experience. Kang Gyu-ri, who defected from North Korea in 2023, first encountered BTS’s disco-infused global hit *Dynamite* while still living in a coastal North Korean county, where families could pull South Korean TV signals across the water with homemade antennas. Even though she did not understand the song’s English lyrics when she first heard it, the upbeat melody won her over immediately. “Everything was shocking. I thought they were Korean like us, but they looked very different,” she said of the colorful hair, stylized makeup, and sharp choreography that define K-pop performances. Rap, a genre entirely absent from state-approved North Korean music, was a novelty at first, but the cool confidence of K-pop idols dancing while they rapped quickly made it a hit among local teens, who began copying the groups’ signature dance moves. By her account, learning a popular K-pop choreography became a widespread underground trend, with groups like 2010s electro-pop outfit Teen Top gaining a massive following among young people.
Unlike the state-mandated music of North Korea, which almost exclusively centers on themes of revolution and political loyalty, K-pop and other South Korean music offers North Koreans something entirely new: songs about love, personal struggle, joy, and self-acceptance. For Hannah Oh, a 25-year-old defector who fled North Korea in 2019, smuggled SD cards of South Korean music often had corrupted file names, leaving her with no way to know the title or artist of the songs she listened to. She focused on the lyrics, and one sentimental ballad stayed with her for years: after she arrived in the South, she eventually identified it as *It’s Not Too Late* by 1990s popular duo Green Zone. “It was all in Korean, so it was much easier to understand than the K-pop I was listening to,” she said. “It was the first time I thought, ‘so this is how people express love.’”
Consuming this forbidden content comes with extreme risk. Oh recalled hiding her contraband music on a separate SD card, keeping an empty card ready to hand over to authorities if she was searched. Public criticism sessions and public executions are used to deter people from accessing foreign media: in 2022, three North Korean teenagers were reportedly publicly executed for distributing South Korean content, and Kang says she knew two young boys who were executed for possessing forbidden media. The North Korean regime has worked for decades to isolate its population from outside influence, framing life under the Kim family as superior to all other alternatives and cracking down on any information that suggests greater freedom exists across the southern border. The isolation is intentional: it is central to the regime’s hold on power.
Even with these harsh penalties, North Koreans continue to seek out South Korean music, calling it their “breathing hole” and “window to the outside world.” A 2023 survey of North Korean defectors found that 98% had consumed South Korean film or television before escaping, and 80% said the content increased their curiosity about the South and shaped their speech, fashion, and cultural habits. For Oh, this cultural shift is exactly what the regime fears: “Some start wearing shorter skirts or dyeing their hair. Once people begin expressing themselves, it affects a system where everyone is supposed to think and move together.” For Kang Gyu-ri, exposure to K-pop and South Korean media was the direct reason she decided to escape: after seeing glimpses of a freer life, the contrast with North Korea’s surveillance and control became impossible to ignore. “It was our breathing hole, our window to the outside world. People risk their lives for it because they gain hope to endure another day,” she said.
For defectors who have built new lives in South Korea, K-pop has continued to play a transformative role, helping them adjust to a new country and embrace their own identities after decades of hiding. Lee Yeon-su struggled to adjust to life in South Korea after her escape, facing discrimination in job searches and hiding her North Korean origins for years. That changed when she discovered BTS, joined the group’s global fandom known as ARMY, and began attending events and connecting with other fans. For the first time, she felt comfortable sharing her background, and she found the group’s message of self-acceptance—central to their *Love Yourself* album trilogy—deeply resonant. The track *Answer: Love Myself*, with its lyrics encouraging listeners to embrace even their past mistakes and scars, helped her find the courage to stop hiding her identity. “I found the courage to stop running and face that part of myself,” she said. “As I understood myself, I found I had more room in my heart to embrace others.”
Other defectors report similar experiences of connection and healing. Hana Kang, who arrived in South Korea 20 years ago, found that BTS’s 2017 track *Spring Day*, a meditation on separation and longing, perfectly captured the quiet homesickness she feels for the family and hometown she left behind in North Korea. For both Hana and Lee, BTS’s open discussion of their own struggles and hardships resonated deeply, giving them the confidence to keep pushing forward with their own new lives. “Looking at them made me think, ‘If they can keep trying like that, maybe I can too,’” Hana said.
For newer defectors like Hannah Oh, life in South Korea brings a different kind of change: the freedom to choose not just to listen to music, but to build any life they want. “There were so many other things I could do,” she said. “In a way, I’m now living in the kind of world I used to only see in dramas.” Even as the North Korean regime doubles down on its crackdown on foreign media, K-pop continues to spread across the border, proving that the desire for personal expression and freedom cannot be contained by censorship or force.
