Sulli’s Brother Claims He Has 37-Minute Audio Recording Involving Former Manager

Sulli’s older brother has claimed that he possesses a 37-minute call recording involving his late sister’s former manager, bringing new scrutiny to a sensitive dispute tied to the late singer-actress’s private life. The claimed Sulli audio recording was described in social media posts and subsequent reports as containing references to Kim Soo-hyun, IU, Lee Ro-be, SM Entertainment, mental health treatment, and parts of Sulli’s private life.¹

The claim emerged in reports published on May 22, after another post from Sulli’s brother on May 21 was interpreted by some outlets as a warning connected to Kim Soo-hyun, though that earlier post did not name him directly.² The posts have been framed by Korean entertainment outlets in the context of renewed public discussion about Kim Soo-hyun after police findings in a separate case involving late actress Kim Sae-ron.³

Sulli Audio Recording Claim Centers on 37-Minute Call

Starnews reported that Sulli’s older brother wrote on May 22 that he had “a 37-minute recording of a call with my sister’s former manager,” and said the recording included content involving Sulli’s private life.¹ Moneycontrol also reported on May 24 that he claimed on Instagram to have a 37-minute recorded phone call with Sulli’s former manager, and that the claimed audio mentioned Kim Soo-hyun, IU, Lee Ro-bae, SM Entertainment, mental health treatment, and private matters connected to Sulli.⁴

The post, as summarized by Starnews, did not present the full recording publicly in the source material provided. The available reports identify the recording as a claim by Sulli’s older brother, not as an independently verified audio file released for public review. That distinction is important because the reported contents remain allegations based on his description of the recording.

Starnews also reported another line from the same social media activity, in which Sulli’s brother said he had many questions he wanted to ask but was holding back for his mother’s sake.¹ Xports News, via Namu News, reported a similar account, saying he wrote that he had a 37-minute phone recording involving his sister’s former manager and that he stated there was no falsehood in what he was presenting.⁵

The available reports do not state that any named individual mentioned in the post has confirmed the contents of the alleged recording. They also do not provide the full audio, a transcript, or an official authentication of the recording. As a result, the public record described in the sources is limited to the brother’s claim and the surrounding reporting.

Earlier Post Was Read as a Warning

TV Chosun reported that on May 21, Sulli’s older brother posted a message that some interpreted as being aimed at Kim Soo-hyun, although the message did not name him directly.² The post included the phrase, “The moment you crawl back out, it’s round two,” as rendered in English by SBS Star.⁶

Moneycontrol reported a similar translation of the message as, “The moment you make a comeback, the second round begins,” and linked it to public discussion about whether Kim Soo-hyun could resume activity.⁴ TV Chosun also reported another phrase from the post, translated in substance as, “The choice is yours.”²

SBS Star described the May 21 post as cryptic and said it appeared after police-related reports about separate allegations involving Kim Soo-hyun and Kim Sae-ron.⁶ The outlet also summarized earlier claims made by Sulli’s brother about the 2017 film Real, while noting that Kim Soo-hyun’s agency Goldmedalist had denied coercion allegations in April. In that agency statement, Goldmedalist said the role of Song Yoo-hwa, played by Sulli, included bed scenes from the script stage.⁶

SBS Star further reported that Sulli’s brother later said he had learned there was no coercion based on several testimonies.⁶ That sequence has made the current recording claim part of a broader discussion involving earlier remarks, agency denials, and later clarification, rather than a standalone official finding.

Separate Kim Sae-Ron Allegations Form the Background

The latest posts were reported shortly after police conclusions in a separate case involving allegations that Kim Soo-hyun had dated late actress Kim Sae-ron when she was a minor. Korea JoongAng Daily reported on May 21 that police concluded those allegations were false, citing an arrest warrant application.³

The same report said police alleged that KakaoTalk screenshots and an audio file presented by Kim Se-eui of the Garosero Research Institute were fabricated or manipulated, including edited names in chat logs and AI-manipulated audio.³ Police were quoted in the warrant application as saying the suspect distributed false information with the intent to defame Kim Soo-hyun.³

TV Chosun reported that prosecutors had requested an arrest warrant for Garosero Research Institute head Kim Se-ui in a separate case involving alleged false claims about Kim Soo-hyun and Kim Sae-ron.² Starnews and Xports News also noted the police findings as part of the timing around Sulli’s brother’s later posts.¹⁵

Sulli’s Brother Claims He Has 37-Minute Audio Recording Involving Former Manager stage concept

The current record therefore contains two separate layers: a police-backed conclusion concerning the Kim Soo-hyun and Kim Sae-ron allegations, and Sulli’s brother’s unverified claim that he has a 37-minute recording involving Sulli’s former manager. The reports available so far do not establish the contents of the alleged recording beyond what Sulli’s brother claimed in social media posts.

For now, the story remains centered on a claim, not a released or officially authenticated recording. The sensitive nature of the allegations, the number of named figures, and the connection to separate police findings have kept the issue under public attention, but the source material supports only a cautious conclusion: Sulli’s brother says the recording exists, while its contents and evidentiary value have not been independently confirmed in the cited reports.
