Kim Soo Hyun cheated on Kim Sae Ron? Cheating accusations fly as his alleged romance with Idol-actress?comes?to?light
Meanwhile, Kim Soo Hyun's upcoming K-Drama "Knock-Off" has reportedly been put on indefinite hold. This has cast uncertainty over one of Disney+ Korea's most anticipated and costly productions release.

It seems that with each passing day, more shocking revelations emerge about Kim Soo Hyun and his scandals surrounding late actress Kim Sae Ron. Recently, it was revealed that the actor had a past relationship that had remained undisclosed until now. Reports claim that Kim Soo Hyun was romantically involved with an idol-turned-actress, referred to as "Actress A," during his military service from 2017 to 2019.
Korean news outlet Money Today (MT) exclusively reported that Kim Soo Hyun and Actress A began dating around 2016 and were together for about three years. However, this seems to clash with Kim Sae Ron's claims of her relationship with Kim Soo Hyun from late 2015 until July 2021.
Kim Soo Hyun and 'Actress A' dating history
The report explained that the two actors grew close while working under the same agency, KEYEAST. Kim Soo Hyun, who originally debuted under M.Boat in 2007, moved to KEYEAST in 2010 and was there until 2019 before founding his own label, GOLD MEDALIST.
The relationship with Actress A reportedly ended in the spring of 2019, just months before Kim Soo Hyun completed his military duty.
Industry insiders cited by MT described the relationship as an "open secret" within the entertainment industry, suggesting it would have been unlikely for Kim Soo Hyun to be simultaneously involved with Kim Sae Ron.
Another source claimed that Kim Soo Hyun's relationship with Kim Sae Ron lasted only a year, from 2019 to 2020.
Korean netizens still skeptic
Despite the report, a majority of Korean netizens continue to support Kim Sae Ron's earlier allegations, accusing Kim Soo Hyun of cheating. Many cited letters he allegedly sent to Kim Sae Ron during his military service, along with other materials her family provided to the Garosero Research Institute, as proof of their relationship.
Public sentiment online has grown increasingly critical, with many mocking Kim Soo Hyun for "shooting himself in the foot" by letting contradictory stories come to light.
Korean netizens react
"So he was cheating on her too?"
"He even cheated on her? Wow."
"Is he... stupid, maybe?"
"Why do I get the feeling 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 fcking dck move."
