On March 10, Kim Se-ui of Garo Sero Institute revealed details from a phone conversation with Kim Sae-ron’s aunt. According to her, Kim Sae-ron and Kim Soo-hyun began dating in 2015 when she was 15 years old, while he was 27. Their relationship reportedly lasted six years, ending in 2021. In 2019, after Kim Soo-hyun founded his own agency, Gold Medalist, Kim Sae-ron chose to sign with him instead of renewing her contract with YG Entertainment.

Amid the resurfacing controversy surrounding Kim Soo-hyun and Kim Sae-ron, past interactions between the two actors are being reexamined by netizens. One notable instance is when Kim Sae-ron sent a coffee truck to the filming set of “It’s Okay to Not Be Okay” in 2020 to show her support for Kim Soo-hyun.
Gold Medalist later paid 700 million won (approximately $483,000) in compensation related to Kim Sae-ron’s DUI accident. Initially, the company did not ask her to repay the amount, but in 2024, they allegedly demanded reimbursement.

However, on the shocking live broadcast by Garo Sero Institute on March 11, 2025, new details emerged regarding the alleged legal dispute involving Kim Soo-hyun. Contrary to previous reports stating that his agency, Gold Medalist, demanded 700 million KRW in damages, Garo Sero claimed that the actual demand was an astronomical 20 billion KRW.

According to KoreaBoo, though the exposé was made public only in March 2025, a comment from a netizen discussing their alleged relationship had already surfaced weeks prior. The comment, posted under a YouTube video about Kim Sae-ron’s legal troubles and passing, stated, “They dated for a long time, at least over six years. After her incident, he wouldn’t even give her a second glance, so it’s true that she asked him for help at the very least.”
With past rumors resurfacing and new allegations coming to light, the controversy surrounding Kim Sae-ron and Kim Soo-hyun continues to grow.
