Korean actor Kim Soo-Hyun has declined resurfaced allegations linking him romantically to the late actor Kim Sae-Ron, following a string of controversial claims circulated by far-right YouTube channel HoverLab Inc, aka Garosero Yeonguso.

The rumours, resurfacing after her tragic passing last month, were spread by the YouTube channel Garosero Research Institute, which claimed their alleged relationship began when Sae Ron was 15 and he was 27.

In a video released on March 10, the YouTube channel stated it had verified the claims with Kim Sae Ron’s parents and included a phone interview with a family member. Kim Soo Hyun’s agency quickly dismissed the allegations and warned of legal action.

In response, Garosero mocked the lawsuit threat, writing, “Even BTS once said they would take legal action against us, how did that turn out? Everyone enlisted in the army.”

Kim Sae Ron’s father, however, announced plans to sue the YouTuber for contributing to his daughter’s distress during her DUI controversy.

Sae-ron, who began her career as a child actor with critically acclaimed roles in A Brand New Life 2009, The Man From Nowhere 2010, had largely withdrawn from the public eye following her drunk driving incident in 2022.

The accident led to widespread backlash and the loss of multiple acting roles. She was 24 when she passed away last month, with reports indicating she had been attempting to relaunch her career through smaller projects and stage work.
