These details have since convinced netizens that the late actress Kim Sae Ron was telling the truth.
In an exclusive coverage, Korean news outletMoney Today (MT) reported that actorKim Soo Hyunwas in a relationship with an idol-turned-actress when he was serving his military duty from 2017 to 2019.

On April 25, 2025 (KST), MT reported that Kim Soo Hyun dated “Actress A” for about three years, starting around 2016. The exclusive news report noted that this “contradicts the earlier claim made by the late actress Kim Sae Ron, who said she dated Kim Soo Hyun from late 2015 until July 2021.”
According to MT, Kim Soo Hyun and Actress A became close as stars signed under the same management company at the time—KEYEAST. Kim Soo Hyun debuted in 2007 with M.Boat but moved to KEYEAST in 2010 and stayed signed with them until 2019 when he established GOLD MEDALIST. The two broke up around spring 2019, about three months before Kim completed his military service.

MT quoted an industry insider who claimed, “It was a well-known secret in the entertainment business that Kim Soo Hyun and Actress A were dating, so it’s unlikely he was seeing Kim Sae Ron at the same time.” The insider added, “It seems Kim Soo Hyun’s side is refraining from commenting to keep Actress A out of it all.”
MT reported that another source claimed, “Kim Soo Hyun only dated Kim Sae Ron for one year, from 2019 to 2020.”

The exclusive, however, has since convinced Korean netizens that the late actress Kim Sae Ron and her friends were telling the truth about Kim Soo Hyun cheating on her multiple times.

Based on the letter that Kim Soo Hyun sent Kim Sae Ron while serving in the military, and other material that the bereaved family has shared with Garosero Research Institute as “proof” of their relationship, most expressed skepticism toward the exclusive and mocked Kim Soo Hyun for “shooting himself in the foot.”

- “So he was cheating on her too?”
- “He even cheated on her? Wow.”
- “Is he… stupid, maybe?”
- “Why do I get the feeling that he was cheating on her?”
- “He just keeps making one bad move after another… please stop.”
- “Kim Star is self-destructing at this point.”
- “As in… If he wasn’t cheating on her, then he sexually harassed her.”
- “Is he outing himself as a cheater? Also… Based on the details given in the exclusive, people will be able to narrow ‘Actress A’ down to a certain person. So unfair to her, too. What a f*cking d*ck move.”
- “He even cheated on her?! What a POS.”
- “He’s self-destructing.”
- “What the hell is wrong with this guy…”
