She was born on June 23, 1994, in Seoul, an only child of working parents in the Cheongdam neighborhood. She was tall — eventually 1.72 m — and gangly, the kind of teenager who, in middle school photographs, looks like she is trying to fold herself in half. She did not, by her own account, find modeling. Modeling found her: a stranger handed her a card in a department-store food court when she was 16, and she signed with the agency ESteem two years later.
Korea's Next Top Model (2013) put her on the public radar. She placed second, watched the winner's career stall, and made a quiet decision to leave for New York. From 2016 onward she lived mostly in a sublet in Bushwick, walked 1,600-plus shows in four years, opened Louis Vuitton, Chanel, Fendi, and Marc Jacobs, and was named — by models.com — model of the year for 2017. The Cut described her as 'the catwalk's most photographed Korean in a decade'. She had a tight circle of model friends, hated being interviewed, and considered acting only because, as she would later say, 'walking is short, and a film is long, and I wanted to know if I could survive something long.'
She enrolled with Saram Entertainment in 2020 and auditioned for Squid Game on tape. The director Hwang Dong-hyuk, who had cast her partly on Lee Jung-jae's recommendation, has said her audition reel made him cry. Sae-byeok — withholding, watchful, capable of switching from defiance to vulnerability without warning — was the role of the series and arguably the one most responsible for the show's emotional grip. When the series dropped on September 17, 2021, Jung's life, in her own description, became 'a place I did not recognize.'
She won Best Actress in a Drama Series at the Screen Actors Guild Awards in February 2022, an unprecedented win for a Korean actress and one she received in a sky-blue Louis Vuitton dress; she became, weeks later, a global ambassador for the house. Her face that year went on bus shelters from Tokyo to São Paulo, on Vogue covers in five countries, on a Time 100 Next list, and into Instagram saturation. She handled the attention with the same close-mouthed wariness she had brought to Sae-byeok — and protected, almost ferociously, her relationship with the actor Lee Dong-hwi, with whom she has been together since 2015.
Her follow-up choice, when it came, was deliberate: The Governesses, a film adaptation announced with the Korean-American director Joachim Trier, and the Apple TV+ thriller series Disclaimer (2024), where she played alongside Cate Blanchett and Kevin Kline under the direction of Alfonso Cuarón. The reviews of Disclaimer were divided, but Jung's were not: critics on both sides of the Atlantic singled out her stillness and her almost weaponized restraint.
She has, in interviews, been notably resistant to the language of stardom. She talks instead about specific things — a director's note, a costume seam, an early flight. She still lives partly in New York. She has said she will return to modeling, occasionally, because 'walking is the first thing I knew how to do well, and I do not want to forget how.' For an actress whose career did not begin until she was almost 28, she has the perspective of someone who arrived late and is, sensibly, in no hurry.
Squid Game's second season, in which Sae-byeok did not return (she had been killed in season one), aired in December 2024 without her. Jung's career, by then, no longer needed it.
