All you need to know about the ongoing controversy between Kim Soo-hyun and late Kim Sae-ron
On March 11, 2025, Garosero Research Institute released a YouTube report exposing the alleged six-year-long relationship between Kim Soo-hyun and Kim Sae-ron. The two shared a twelve-year age gap, and according to the report, Sae-ron was only 15 years old when Soo-hyun, who was 27 years old, started a relationship with her.
This led to grooming allegations against the actor. Additionally, the report accused the actor and his agency of putting financial pressure on the actress. In 2019, following the establishment of Soo-hyun's agency Gold Medalist, Kim Sae-ron was housed under the same and also participated as the agency's co-founder.
Therefore, in 2022, during Kim Sae-ron's DUI incident, the agency helped her pay the compensation fee of 700 million KRW, which the actress promised to pay off slowly, according to Garosero Research Institute. Kim Sae-ron later left Gold Medalist, and in 2024, the agency demanded that the actress pay back the debt as soon as possible.
However, since she wasn't financially stable to do the same, she reportedly tried to reach out to Soo-hyun to better understand the situation. But the actor allegedly didn't provide any response. With the growing pressure to settle the debt, Garosero Research Institute reported that the actress had taken her own life on February 16, 2025, which falls on the actor's birthday.
The Gold Medalist and Soo-hyun denied these allegations and expressed that though the two were in a relationship, it started only after Kim Sae-ron became a major. Additionally, they also claimed that Kim Soo-hyun was never directly involved in the financial conflict between the agency and the actress.
Regardless, Garosero Research Institute has been continuously releasing pictures, videos, and other pieces to further prove the underage relationship between the two. Kim Sae-ron's family and Kim Soo-hyun have filed lawsuits against each other, and no proceedings regarding the same have been revealed yet.
