When South Korean actor Kim Soo-hyun found himself embroiled in one of the most explosive celebrity scandals of 2025, it wasn’t just about tabloid rumors—it became a full-blown legal and media showdown. On October 30, 2025, a hearing before the National Assembly of the Republic of Korea took centre stage, where testimony exposed what one witness called a “nation-wide fraud” perpetuated by the Garosero Research Institute. What began with the tragic death of actress Kim Sae-ron has now evolved into a test case for how far misinformation and AI-fabricated evidence can go before institutions step in.
The Genesis
The late Kim Sae-ron—who rose to prominence in films such as A Brand New Life and the TV series The Queen’s Classroom—was found dead in her Seoul home in March 2025, in an apparent suicide. Her passing triggered renewed scrutiny of her personal life, particularly her past connection to Kim Soo-hyun, one of Korea’s most recognized actors, known globally for My Love from the Star and Queen of Tears.
Shortly after her death, Garosero Research Institute—an online channel notorious for political sensationalism—published allegations claiming Kim Soo-hyun had dated Kim Sae-ron when she was underage and had pressured her to repay a 500 million-won debt related to her 2019 car accident.
Kim Soo-hyun’s agency denied the accusations, clarifying later that the two had dated briefly between 2019 and 2020 when Kim Sae-ron was already an adult. But by then, the accusations had spread across news outlets and social media, triggering a wave of public hostility and speculation that jeopardized the actor’s career.
The Man Behind the Allegations
At the center of these allegations is Kim Se-ui, a former journalist turned political YouTuber who founded the Garosero Research Institute. Once a reporter for MBC, Kim Se-ui reinvented himself as a “citizen journalist,” gaining millions of views for videos claiming to expose corruption and celebrity scandals.
However, his brand of activism has long been controversial. Garosero is infamous in South Korea for publishing unverified claims and politically charged narratives. Supporters see Kim Se-ui as a whistleblower; critics describe him as a provocateur who thrives on outrage.
In the Kim Soo-hyun case, Kim Se-ui’s channel released what it claimed were voice recordings, photos, and chat logs proving misconduct by the actor. These materials were later revealed to have been fabricated—some allegedly generated with AI tools—triggering a backlash that now threatens Kim Se-ui’s entire operation.
The Whistleblower: “The God of Business” Eun Hyun-jang
The scandal might have ended as just another unresolved online feud—until Eun Hyun-jang, a YouTuber known as “The God of Business,” came forward with insider information that turned the case into a national issue.
Eun Hyun-jang, a well-known broadcaster and entrepreneur, is famous for tackling corruption and unethical business practices on his platform. His reputation for investigative content earned him credibility with lawmakers, leading to his invitation to testify before the National Assembly about the Garosero case.
During the hearing, Eun revealed that he had personally acquired 50% of the shares in Kim Se-ui’s company to examine its internal operations. What he found, he claimed, was alarming: Garosero was earning billions of won through monetized scandal content, while facing fines of only a few million won for legal violations.
“Cyber wreckers can easily earn billions, yet the fine is only about three million won,” Eun told the Assembly. “Who wouldn’t want to become one under such a system? It defies common sense.”
He went on to accuse Kim Se-ui of staging a “nationwide fraud” through three major press conferences. According to Eun’s testimony, Garosero forged KakaoTalk messages, fabricated photo evidence, and used AI voice manipulation to create the illusion of authenticity. He stated that all of the materials released were false and that the fabricated evidence directly caused Kim Soo-hyun’s professional losses, including advertising lawsuits and contract suspensions.
Eun also disclosed plans to submit all evidence and financial records to the court, pledging to expose what he called the “industrial scale” of Korea’s cyber-defamation economy.
“When I examined his financial records, I found he was making an insane amount of money. They even spend their earnings at nightclubs,” he said, emphasizing how profit-driven and morally unchecked the system has become.
Eun concluded his testimony by urging lawmakers to implement a punitive damages system to hold digital content creators accountable for defamation and malicious misinformation.

The National Assembly Hearing: A Turning Point
The National Assembly hearing on October 30 became a watershed moment. Eun Hyun-jang, a YouTuber and whistleblower, testified that Garosero fabricated the evidence it had presented to the public—including forged KakaoTalk messages, edited photos, and AI-generated voice recordings. According to Eun, these fabrications were part of an orchestrated smear campaign intended to destroy Kim Soo-hyun’s reputation and drive public outrage.
The revelation shook the chamber. Lawmakers expressed alarm not just at the potential criminality of Garosero’s actions but at how easily manipulated evidence had been accepted as truth in the digital sphere. Chairwoman Choi Min-hee vowed to pursue further inquiry, calling the incident “a serious wake-up call about the consequences of unchecked online influence.”
Legal Stakes and the Wider Fallout
Kim Soo-hyun’s agency, Gold Medalist, has filed a civil suit seeking over 12 billion won (approximately $8.2 million USD) in damages against Garosero and the family of Kim Sae-ron, citing defamation and the distribution of falsified information. Earlier this year, a Seoul court approved the seizure of two high-value apartments belonging to Garosero’s founder, Kim Se-ui, located in Gangnam and Seocho, collectively worth nearly $3 million.
Beyond the financial dispute, the case highlights a major societal concern: the rising weaponization of AI-generated “proof” in online smear campaigns. The ability to alter photos, mimic voices, and fabricate chat logs blurs the line between reality and invention—leaving reputations vulnerable to digital manipulation.
Legal experts in South Korea have noted that this case could push lawmakers to introduce stricter penalties for AI-based defamation and evidence fabrication, setting a global precedent for regulating misinformation in the era of generative technology.
Why It Matters Globally
To North American readers, this story may sound like a uniquely Korean scandal, but its implications are far wider.
- Digital Truth on Trial: The case serves as a warning about how easily deepfakes and AI-edited content can destroy reputations—and how existing legal systems struggle to keep up.
- Global Hallyu Economy: Kim Soo-hyun is one of South Korea’s most internationally recognized stars. His brand power spans from Netflix dramas to luxury endorsements, making his reputation a matter of global commerce.
- Legal Precedent for Creators: The case could influence how nations handle defamation and evidence tampering in the influencer economy, where creators and public figures are equally exposed to viral misinformation.
The Broader Cultural Reckoning
The scandal has also revived public debate about South Korea’s unforgiving celebrity culture, where public figures are often vilified overnight. The country has witnessed several high-profile cases where online rumors preceded tragedy—highlighting the emotional and social toll of digital mob justice.
Kim Soo-hyun’s case now represents both an individual’s pursuit of justice and a national reckoning with media ethics, online responsibility, and the human cost of misinformation. It has prompted lawmakers and entertainment insiders alike to question how South Korea can protect its cultural exports—the very stars driving the global “K-wave”—from the darker forces of its digital landscape.
What Comes Next
The court hearing scheduled for November 2025 will determine whether Garosero’s fabricated evidence constitutes criminal fraud and defamation. A ruling in Kim Soo-hyun’s favor could lead to historic changes in South Korean media regulation and serve as a template for how governments can respond to AI-driven disinformation.
For Kim Soo-hyun, it remains a deeply personal fight—but one with global resonance. What began as a tragic story about loss and rumor has transformed into a test of truth in the age of artificial intelligence—one that will likely define how fame, justice, and digital accountability coexist in the modern era.
