Kim Soo hyun Dating Allegations Challenged by Reported Police Findings on Altered KakaoTalk Messages

Police reportedly trace disputed 2016 messages to another celebrity

A forensic examination of four phones used by the late actress Kim Sae ron and about 200 cloud stored KakaoTalk screenshots reportedly identified another celebrity, rather than actor Kim Soo hyun, as the person behind a disputed 2016 conversation. Investigators are said to have found the other celebrity's real name at least twice in the original messages, alongside references to that person's colleagues.

The findings challenge a central piece of evidence used by the YouTube channel Garosero Research Institute, commonly called Gaseyeon, to allege that Kim Soo hyun dated Kim Sae ron while she was a minor. Reports published on October 13 say the original conversation displayed an anonymous sender label and that the version released publicly was altered to show Kim Soo hyun's name.

Kim Soo hyun has acknowledged a relationship with Kim Sae ron after she became an adult in 2019, while denying that they dated during her childhood. Police reportedly found no material supporting the alleged earlier relationship and declined to refer a complaint against him to prosecutors.

These developments need to be distinguished from a final judicial finding. The detailed forensic conclusions are described in news reports, rather than a publicly reproduced police report or court judgment. Gaseyeon operator Kim Se ui has denied wrongdoing, and his reported detention and indictment do not establish guilt. Reports also conflict on the year of his detention, leaving part of the legal chronology unresolved.

What investigators reportedly found on four iPhones

The examination covered an iPhone 7, iPhone 8, iPhone SE and iPhone 13 Mini previously used by Kim Sae ron. Investigators reportedly recovered messages and photographs and compared those records with screenshots stored in her cloud account.

The iPhone 7, which she used during 2017 and 2018, reportedly contained three calls involving Kim Soo hyun. Accounts giving the direction of those calls say all three were made by Kim Sae ron to him. No material supporting a romantic relationship during that period was reportedly found on the iPhone 8 or the other devices.

Investigators also reportedly established that she saved Kim Soo hyun's telephone number in October 2017, more than a year after the disputed 2016 messages. That date is relevant to the contact history, although saving a number later does not by itself prove that two people had no earlier contact.

The examination reportedly found evidence of close relationships with at least four other men and almost no references to Kim Soo hyun in conversations with relatives and acquaintances. Those details describe the scope of the review. They do not establish the nature or legality of any other relationship, and the men have not been publicly identified in these accounts.

Why the sender's identity matters

The disputed conversation included intimate language that Gaseyeon presented as evidence of a relationship involving Kim Soo hyun in 2016. The central issue is whether that language was correctly attributed to him, rather than whether the messages sounded affectionate.

Police reportedly compared conversations carrying real names with those displaying anonymous labels. In the original exchange at issue, Kim Sae ron is said to have addressed the other celebrity, identified publicly only as Person A, by name twice. References to work colleagues reportedly matched Person A's professional circle and had no connection to Kim Soo hyun.

Writing habits provided another comparison. Person A reportedly followed standard Korean spelling and spacing, while Kim Soo hyun used different informal spellings, expressions and consonant abbreviations representing sounds. Those differences supported the reported identification, alongside the names and contextual details within the conversation.

The evidence described here is more specific than a simple judgment about writing style. A person's name appearing inside a conversation and references to identifiable colleagues can help establish who was participating even when the displayed contact name is missing. None of those details, however, authorizes speculation about Person A's identity or establishes that the person committed an offense.

How the public screenshots were allegedly changed

Reports describe the original sender label as Korean variants of Unknown. Some accounts say Kim Sae ron's family removed Person A's name before the material reached Gaseyeon, and that the channel subsequently inserted Kim Soo hyun's name. Those remain allegations about the handling of the material, not established findings against the family in a court judgment.

A Gaseyeon employee reportedly told police that Kim Se ui instructed staff to change the sender label to Kim Soo hyun. A separate account says investigators identified two employees who used Photoshop to alter the conversation display under his instructions. That account also says the original lacked the Kim Soo hyun profile photograph shown in the publicly released version.

Changing a contact label or profile photograph can make a screenshot appear to identify a participant without changing the words of the conversation. This is why the distinction between the original messages and the published image matters: an apparently authentic exchange can still be falsely attributed.

The reported police assessment was that the channel presented the conversation as Kim Soo hyun's despite knowing the participant's identity had not been established. The later reports identifying Person A add a further claim. Determining who changed which elements, and what each person knew, remains part of the criminal case.

The photographs point to a different period

Photographs released as supporting evidence reportedly date mostly from 2019 and 2020, when Kim Sae ron was an adult and attending her first two years of university. That period matches Kim Soo hyun's position that their relationship began after she reached adulthood.

The distinction matters because a photograph showing the two together can support evidence of contact at the time it was taken. It cannot, without additional evidence, establish that a relationship began several years earlier. The reports say most of the photographs fit the adult relationship Kim Soo hyun acknowledged, rather than the alleged relationship during her childhood.

Kim Soo hyun initially presented a private assessment challenging the attribution of the 2016 messages and sought an investigation. His defense therefore had two separate elements: he did not deny an adult relationship, but disputed the identity attached to the earlier chats and the dates assigned to supporting material.

The reported device examination, contact records and photograph dates address different parts of that defense. Together, they challenge the publicly presented chronology more directly than a denial alone, although the full forensic documentation has not been reproduced in these reports.

The audio allegation and conflicting recordings

The investigation also reportedly examined an audio recording presented at a May 7, 2025, press conference as Kim Sae ron's account of dating Kim Soo hyun while she was a minor. Police are said to have concluded that the voice file was manipulated using generative artificial intelligence.

Generative AI can produce speech resembling a real person's voice. A familiar sounding voice is therefore not enough to authenticate a recording. Its origin, the original file and the circumstances in which it was supposedly recorded are separate questions.

The person who supplied the recording reportedly approached Kim Soo hyun's agency on April 5, 2025, offering different audio that supported a relationship after adulthood. The person sought money and a future advertising arrangement. At least four versions containing conflicting accounts reportedly reached the agency or other recipients.

Those contradictions are distinct from the technical question of whether the voice was artificially generated. They provide a reason to examine the supplier's credibility and the files' origins, but do not substitute for a forensic conclusion.

There is also a dispute over the National Forensic Service's role. Kim Se ui maintained that the recording had been checked and cited the agency. One detailed account says police commissioned the examination and that the agency found verification impossible because it had not received an original file. An inconclusive examination is neither proof of authenticity nor a finding of fabrication. The reported police conclusion must therefore be kept separate from that account of the agency's assessment.

A timeline with one unresolved date conflict

The controversy developed through public broadcasts, press conferences, complaints and an investigation. Several dates are stated consistently, while accounts of the detention year conflict:

• 2016: The disputed KakaoTalk conversation took place, according to the allegations and the reported forensic review.
• October 2017: Kim Sae ron reportedly saved Kim Soo hyun's telephone number.
• 2019 and 2020: Most of the photographs released as evidence were reportedly taken during the adult relationship Kim Soo hyun acknowledged.
• March 10, 2025: Gaseyeon began its broadcasts targeting Kim Soo hyun, according to an account that also identifies subsequent press conferences in March 2025.
• March 27 and March 31, 2025: Representatives of Kim Sae ron's family presented messages publicly, followed by Kim Soo hyun's press conference denying a relationship during her childhood.
• May 7, 2025: Gaseyeon presented the disputed voice recording at a press conference.
• May 14 and May 20: Gangnam Police reportedly submitted a detention request to prosecutors, followed by a prosecution application to the court.
• May 26 and May 27: Reports describe a detention hearing and warrant decision, but disagree on whether the detention occurred in 2025 or 2026.
• June and October 13, 2026: An account dated October 13, 2026, says Kim Se ui was indicted while detained in June and describes the later forensic findings.

One detention report explicitly gives May 27, 2026, while another account places the detention in May 2025. The year cannot be resolved from these accounts alone. It would be misleading to combine them into a single verified chronology.

The reported grounds for detention were concerns about destruction of evidence and flight. A subsequent challenge to continued detention was reportedly rejected. Those decisions concern custody during proceedings, rather than whether the charges have been proved.

Criminal complaints and the financial stakes

Kim Soo hyun filed criminal complaints alleging defamation through false statements against Gaseyeon and members of Kim Sae ron's family. Her family separately complained to police about alleged violations of the Child Welfare Act and other offenses. Police reportedly closed that complaint without referring it to prosecutors.

The charges attributed to Kim Se ui include defamation under the Information and Communications Network Act, violations of legislation concerning sexual violence and stalking, and, in an earlier detention account, threats. The differing descriptions may concern different stages or parts of the proceedings. The reports do not reproduce a complete final indictment.

Prosecutors reportedly identified 115 million won in advertising revenue and 54.4 million won in donations associated with the broadcasts, a combined 169.4 million won. Advertising accounts for approximately 68% of that sum and donations for 32%. Whether particular receipts constitute unlawful proceeds remains a legal question, not an automatic consequence of receiving revenue.

The original account describes more than 25 broadcasts advancing the allegation. Another account counts 21 broadcasts in the first month. Those figures need not conflict because they cover different periods. The channel's subscriber count reportedly rose from about 900,000 to more than one million in less than a month.

What remains unresolved for Kim Soo hyun and Gaseyeon

The financial damage claimed by Kim Soo hyun's representatives is substantially larger than the reported broadcast revenue. His lawyer, Ko Sang rok, estimated losses of about 30 billion won after nearly 20 advertising contracts and acting work were interrupted. That is a representative's estimate, not a court assessed damages award.

Kim Soo hyun also brought a civil damages claim seeking 12 billion won. The amount sought in that case and the broader estimate of losses are different measures and should not be treated as interchangeable. No outcome of the civil claim is identified in these reports.

An account dated October 13, 2026, says he had resumed some work through an overseas advertising shoot and attended a domestic awards ceremony the previous month. Those appearances suggest a return to public activity, but do not establish how much work or income has been restored.

The most consequential remaining issues are the outcome of the criminal prosecution, responsibility for the alleged alterations, the authenticity and origins of the recordings, and the civil damages case. No next trial date or judgment deadline is given. The reported refusal to refer the family's complaint is a concrete procedural development, while the allegations against Kim Se ui still require adjudication.

The distinction is essential for both sides: the reported forensic findings challenge evidence used to accuse Kim Soo hyun, but they do not justify treating every allegation against Gaseyeon, the family or Person A as a proven fact.
