Dahyun made her acting debut in 2025 with the film You Are the Apple of My Eye, where she received several Best New Actress awards. She later appeared in the independent film Run to You (2025) and in the television series Love Me (2025–2026).

Early life and education Dahyun was born in Seongnam, Gyeonggi, on May 28, 1998. She grew up with her parents and an older brother. As a child, she sang in her Christian church choir and took part in school talent shows. She considered becoming a piano teacher or a prosecutor before pursuing a career in entertainment. She later became the first member of Twice to pursue acting and said it had been a long-standing goal supported by her mother since childhood.

Career Pre-debut activities

Dahyun first gained attention in sixth grade after performing a church dance known as the "eagle dance", which was later uploaded to YouTube. She later auditioned for SM, YG, and JYP and was accepted by all three agencies. After being scouted at a dance festival, she chose to join JYP and trained there for over three years. In 2014, she appeared as the main female character in the music video for Got7's "Stop Stop It". The following year, she competed in Sixteen, a reality television show that determined the lineup of JYP's new girl group.

Beginning with Feel Special (2019), Dahyun increased her contributions to the group's music by writing multiple songs and established herself as one of Twice's primary lyricists. In 2023, she appeared as the female lead in the music video for "Nothing But" by Young K of Day6.

The performance received positive critical attention, and she later received the Rising Star Award at the Busan International Film Festival, the Best New Actress award at the Seoul Global Movie Awards, and the New Star Award at the 29th Chunsa Film Art Awards. Reviews of the series noted her development as an actress following her film debut, and her performance earned her a nomination for Best Newcomer at the Global OTT Awards. That year, her solo track "Chess" was included in Twice's tenth anniversary album Ten: The Story Goes On. On February 11, 2026, JYP announced that Dahyun had sustained an ankle fracture and would miss the remaining North American dates of the group's This Is For World Tour. On April 24, 2026, it was confirmed that she would resume activities beginning with the group's performances at Japan's National Stadium.

She also contributed to the songwriting and composition of the soundtrack for the film You Are the Apple of My Eye. Dahyun has said she often gets ideas for lyrics while traveling and has cited 2PM, Wonder Girls and Rain as early influences on her as a performer.
