Actor Kim Soo-hyun and his agency, Gold Medalist, filed several criminal complaints against members of the late Kim Sae-ron’s family and a person accused of impersonating her aunt. On October 26, 2026, the agency disclosed the police findings and said Sae-ron’s mother and a lawyer for her family had been referred to prosecutors. It said her father was not referred. The agency also said Kim Se-ui of the YouTube channel Garo Sero Institute had previously been detained and indicted in a related case.

Gold Medalist said Sae-ron’s mother and the alleged impersonator were among those referred on allegations that included defamation through allegedly false statements, distribution of camera-recorded footage and attempted coercion. Its statement did not specify which allegations applied to each person. The agency said they had joined Kim Se-ui in spreading false information and that police had found grounds for the referrals.

According to Gold Medalist, police separately investigated people who had not been named in Kim Soo-hyun’s original complaints. The agency said family lawyer Boo Ji-seok was referred on defamation allegations under criminal and information-network laws, while Kwon Young-chan, operator of the YouTube channel Kwon Young-chan TV, was referred on an allegation involving distribution of camera-recorded footage. The agency alleged that the 2 men led 2 news conferences using altered KakaoTalk material and manipulated audio.

Kim Soo-hyun largely suspended his activities after allegations about his private life involving the late Kim Sae-ron emerged in March 2025. At the time, Garo Sero Institute and members of her family claimed the two had dated while she was a minor. Kim Soo-hyun’s side denied the claim that they had dated while she was a minor and pursued criminal complaints and a damages claim. His side also challenged the reliability of material released amid the allegations. In July 2026, police declined to refer a separate child-welfare and false-accusation complaint filed against him by Sae-ron’s family, finding no grounds for the allegations.

Kim Soo-hyun resumed activities in July 2026 with an advertising shoot for the Philippine clothing brand Bench. Kim Soo-hyun appeared on RCTI’s 37th anniversary live broadcast on August 23, 2026, and sang “Dreaming” from the drama “Dream High.” He then presented a popularity award at The Fact Music Awards at Busan Asiad Main Stadium on September 19, 2026. It was his first official appearance in South Korea in about 1 year and 6 months.
