Seoul retailer files ₩2.8 b suit against Kim Soo-hyun, saying scandals wrecked its brand

A mid-tier Seoul retail company referred to in court papers only as “Company D” has sued actor Kim Soo-hyun and his agency GOLDMEDALIST for ₩2.8 billion (≈ US $2 million), alleging that an ongoing personal-life scandal breached an exclusive advertising contract and eroded sales, according to a civil complaint filed on 25 April with the Seoul Central District Court and first reported by YTN Star.

The writ states that the retailer hired the “Queen of Tears” star last September to front a spring–summer campaign but cancelled the deal when unverified rumours claimed he dated the late actress Kim Sae-ron while she was underage. Company D seeks repayment of model fees plus additional damages for what it calls “irreparable brand dilution.”

A spokesperson for GOLDMEDALIST told Maeil Kyungje that the agency “has not yet confirmed receipt of any new court documents” and will “respond firmly once the facts are verified.” The same position was conveyed to Chosun Biz, where the company reiterated that it continues to pursue criminal-defamation complaints against online publishers spreading the allegations.

The new filing is the third advertiser action in ten days. Two other brands—identified in local press as a cosmetics group and a fashion label—lodged separate suits on 29 April seeking a combined ₩3 billion. Taken together, advertiser claims against Kim now stand at roughly ₩6 billion. The running total was highlighted by national wire service Newsis, which noted that further demands are expected if other sponsors follow through on recent legal warnings.

English-language K-culture outlet Allkpop, citing the YTN scoop, stressed how quickly brand partners have moved to distance themselves from the 37-year-old actor since the rumours surfaced in March. At least seven national ads featuring Kim have been withdrawn, and several convenience-store chains have removed in-store displays still bearing his likeness.

The controversy erupted on 10 March when the YouTube channel Garosero Research Institute livestreamed what it claimed were 2015 images showing Kim and Kim Sae-ron together. Within days the story dominated Korean news feeds, prompting a 31 March press conference where Kim tearfully denied any underage relationship and vowed legal action. DMNews explored the fallout in an op-ed on trial-by-media risks and later argued that advertiser flight exposes vulnerabilities in Korea’s endorsement economy even without tested evidence.

Friday’s court papers, excerpts of which were reviewed by YTN, allege that “persistent rumours and the defendant’s insufficient refutation” violated the contract’s morals clause. Company D claims direct losses of ₩1.9 billion from cancelling a May marketing rollout and an additional ₩900 million in projected goodwill erosion measured through social-media sentiment analysis.

Legal specialists say the size of the demand is large but not extraordinary. “Korean endorsement deals frequently include a penalty worth two to three times the annual model fee,” attorney Han Ji-soo of Seoul-based Barun Law said by phone. “If Kim was paid around ₩1 billion up front, a ₩2.8 billion claim sits at the upper edge but within contractual norms.”

The Seoul court is expected to decide within weeks whether to consolidate the three advertiser suits. A combined case would streamline discovery but raise financial stakes. “One verdict could trigger simultaneous payouts,” Han noted, adding that consolidation often nudges parties toward out-of-court settlements.

GOLDMEDALIST maintains that no breach occurred because “all allegations remain unproven and defamatory,” pointing to its own defamation countersuits filed on 18 April. Economic daily Herald Business reported that Kim seeks at least ₩120 billion in damages from three YouTubers and Kim Sae-ron’s family, asserting the images are doctored.

Streaming platform Coupang Play has already postponed the July release of Kim’s detective drama “Beyond Echoes,” telling shareholders it is “monitoring legal developments.” Advertisers, according to agency insiders quoted by Maeil Kyungje, are likewise waiting for the first court hearing before deciding whether to reinstate contract payments or pursue further penalties.

Consumer-rights advocates say the dispute shows why Korea’s lucrative star-endorsement market needs clearer rules. “If a brand claims billions in harm, the public should at least see the basis for that number,” argued Lee Min-kyu, policy chief at watchdog NGO Fair Trade Korea, in comments to Newsis.

The civil docket is currently the fastest-moving part of the case. The Seoul Central District Court typically schedules an initial management hearing within four weeks of filing, meaning Company D’s claim could surface publicly before the end of May. If the court grants a provisional attachment order—a common step in high-value disputes—Kim would be barred from disposing of certain assets until judgment.

Observers view the litigation as a test of celebrity liability in South Korea’s intensely competitive advertising scene. “The Kim Soo-hyun affair shows how a single rumour can erase billions in market value overnight,” Justin Brown wrote recently in a DMNews feature. Whether the actor can claw back endorsements—or whether brands will seek even larger sums—now rests with a court docket that is ticking far faster than the usual PR recovery cycle.

The next milestone will be the court’s decision on consolidation, expected as early as next week. Until then Kim Soo-hyun’s future in commercials, television and perhaps even public life hangs on a handful of legal filings and South Korea’s unforgiving spotlight on scandal.
