Sim Soo-bong Attacked a Teen Onstage. The Fallout Is Still Growing 4 Days Later

The apology didn't stick. Sim Soo-bong publicly attacked 17-year-old singer Kim Da-hyun at the 10th Jinan Highland Trot Festival on the 20th, told organizers to never put Kim on before her again, and then issued a formal statement calling it a "slip of the tongue." Kim Da-hyun said she spoke with Sim by phone, accepted the apology, and asked fans not to worry. That should have been the end of it.

It wasn't.

What Sim Soo-bong actually said onstage

For context: Sim, born in 1955, is 71. Kim Da-hyun, born in 2009, is 17 and still a minor. After Kim's set at the festival in North Jeolla Province, Sim took the stage and immediately turned on her. "That girl who sang before me made my head spin," she told the crowd. "She seems like a young woman who doesn't know what music is, or what life is. It's so hard listening to her sing. Don't put that performer in front of me anymore, I'm so dizzy I'm about to collapse."

She kept going. Music, she said, isn't something you do carelessly. You need life experience, hardship, and then you earn the right to comfort an audience.

Kim Da-hyun's father confirmed to media that his daughter witnessed the remarks directly and broke down crying. Sim's agency later acknowledged the comments were "inexcusable," citing Sim's ongoing concerns about the state of Korean pop music and noise at the venue as context, while making clear neither explanation justified what was said.

The Hidden Singer 8 accounts

What's keeping this alive is a wave of audience posts about a March taping of JTBC's Hidden Singer 8 that featured Sim Soo-bong. The accounts, circulating across online communities, claim Sim scolded and lectured another artist on set, made sarcastic or rude remarks toward civilian contestants, and spent extended time during the taping narrating her own life story rather than engaging with the show's format. One account claims a contestant visibly showed discomfort during the exchange.

None of this has been officially confirmed. These are anonymous audience posts, and the possibility of exaggeration or personal bias can't be ruled out. JTBC and Sim's representatives have not publicly addressed the claims.

But the timing is the problem. When one incident cracks the surface, people start digging. What's circulating now isn't a coordinated attack, it's a pattern of individual accounts from different contexts pointing in the same direction. Whether or not every detail holds up, the volume of it is doing real damage to how the public reads Sim's behavior.

Where things stand

Kim Da-hyun handled her side of this with more composure than anyone twice her age might have managed. Sim Soo-bong issued a full statement, apologized to Kim and her family directly, and the two parties spoke by phone. The personal conflict is resolved.

The public one isn't. The Hidden Singer 8 accounts aren't going away, and older reports of similar behavior at other concerts are starting to surface alongside them. Sim's reputation, built over decades in the Korean trot and pop world, is taking sustained hits from multiple directions at once, and the original apology, whatever its sincerity, is no longer the story anyone is focused on.
