Seoul, South Korea – June 19, 2025 — As Kim Soo Hyun’s legal battle against online defamation continues, the Korean entertainment industry is shaken again. This time, it’s Kim Sae Ron’s former manager filing a defamation lawsuit against YouTuber Kwon Young Chan, accusing him of spreading false and damaging claims tied to the late actress’s personal life and death.
The complaint was officially filed at Seocho Police Station in Seoul and comes just days after a court ruled in favor of Kim Soo Hyun in a similar lawsuit involving online defamation by another high-profile YouTuber.
Referred to as Mr. K, Kim Sae Ron’s ex-manager alleges that Kwon Young Chan uploaded multiple videos with defamatory statements, falsely accusing him of:
“Despite not being a public figure, my face and full name were exposed across thumbnails and videos,” said Mr. K. “The accusations were not only cruel but completely false.”
This lawsuit mirrors the ongoing court battle involving Kim Soo Hyun, whose agency Gold Medalist successfully filed for asset seizure against YouTuber Kim Se Ui of Garo Sero Institute. The court sided with Kim Soo Hyun after months of false rumors about his personal life were spread, damaging his reputation and career.
“These kinds of attacks are not journalism—they’re targeted defamation,” a legal expert told local media. “Kim Soo Hyun’s case may set the tone for how the industry handles malicious content moving forward.”
Mr. K claims he only began working with Kim Sae Ron in 2024 under Management Run, after her 2022 DUI controversy and departure from Gold Medalist. He said he helped her plan a career comeback and was present during a medical emergency.
“I personally called an ambulance and then informed her mother,” he explained. “The YouTuber’s claims that I isolated her or caused her death are not only false—they’re damaging to everyone who cared about her.”
Kwon insists he tried contacting Mr. K multiple times but received no response, which led him to make public inquiries through his content. However, Mr. K alleges that the videos were edited and titled in a way that framed him as guilty before any facts were verified.
The cases involving Kim Soo Hyun and now Kim Sae Ron’s former manager reflect a widening legal crackdown on unverified YouTube content within Korean entertainment. As more public figures take legal action, these lawsuits may redefine boundaries between free speech and online defamation.
