When she was in high school, she went to study in the United States alone after asking her parents tenaciously just for the single reason that she likes English. There, she joined a drama club and had a chance to perform on a musical stage. That experience found her a dream of her own. After returning to Korea, she took her first steps toward her acting dream in earnest, proving her potential by passing the college entrance exam despite her parents' opposition. Later, Shin Do Hyun debuted by making herself known through singer Park Won's music video 'All of My Life' in 2017 and signed an exclusive contract with her agency VAST Entertainment, represented by her acting mentor, Kang Kun Taek. She captured viewers' eyes with her elegant yet mysterious vibe, and after her debut, she was cast as 'So Eun Ji' in Switch: Change the World (2018) through a 400:1 competition and drew attention as her rising star. Since then, Shin Do Hyun has shown stable performances, unlike a rookie, such as The Third Charm (2018) The Banker (2019) Understanding of Social Dance (2019) Love with Flaws (2019) etc., appearing in three or more works in a year in average, showing explosively progress. In 2020, Shin Do Hyun left a deep impression, appearing as 'Bae Jun Hee', an ER Fellow, in Hospital Playlist (2020) a new series by director and Shin Won Ho. Later in 2021, she played her first lead role as 'Na Ji Na' in the Doom at Your Service (2021) and was dubbed the 'Next Generation Actress.' After taking a short break after 'Doom at Your Service,' she took the role of 'Masha' in Anton Chekhov's play 'The Seagull' performed on stage for the first time and captivated the audience with her sincere performance. In an interview after the closing of the play, she said, 'There was a Masha-like side in me when I was younger. I was preoccupied with the idea that I am unfortunate, but acting helped me overcome it. Acting energizes and moves my life,' revealing her passion for acting. After performing on theater stages, Shin Do Hyun made a successful comeback as a leading actor in the 2024 ENA drama 'Brewing Love,' showcasing a strong presence with the support of her Asian fans. In 2025, she is anticipated to make her full-fledged Hollywood debut in the Netflix original series 'The Recruit : season 2.'
