Seo Hyun-jin (born February 27, 1985) is a South Korean actress and singer. Seo debuted as the vocalist of South Korean girl group M.I.L.K. in 2001 and continued until the group disbanded in 2003. She contributed songs as a solo artist after the group disbandment before she transitioned into acting in 2006.

Seo made her acting debut in the musical The Sound of Music (2006) then followed by appearances in several television series and film. She is best known for her leading role as Oh Hae-young in the romantic comedy TV series Another Miss Oh (2016), which gained her wider recognition.

1985–2005: Early life and music career
Seo was born on February 27, 1985, in Dobong District (now Nowon District), Seoul, South Korea. She was scouted by S.M. Entertainment and later debuted as a vocalist of South Korean girl group, M.I.L.K in 2001, under the label's subsidiary BM Entertainment. However, the group soon fell by the wayside due to fierce competition among manufactured bands, which led to one of the members quitting before they completely disbanded in 2003. After M.I.L.K. was dissolved, Seo attended Dongduk Women's University, where she majored in applied musicology to keep her dream of a singing career alive. Seo contributed songs to a few soundtracks and SM Town compilations as a solo artist.

2006-2014: Acting debut and further roles
Seo had the chance to perform in her first musical, The Sound of Music in 2006, which she saw as the turning point in her acting career.

Supporting roles followed in the period drama Hwang Jini (2006), TV police procedural H.I.T (2007), and the queer film Ashamed (2011). Seo first drew attention for her subtler performance in The Duo (2011), as a neighborhood tomboy who later becomes a gisaeng. She played her first villain in Feast of the Gods (2012), as an overly ambitious chef caught in a rivalry. Seo was then cast in leading roles for two historical dramas The King's Daughter, Soo Baek-hyang (2013) and The Three Musketeers (2014).

Seo has also frequently appeared in projects directed by her best friend, actress Ku Hye-sun, notably in the short film The Madonna and in the feature film Magic, in which she had her first leading role.

2015–present: Rising popularity


Seo said the character that most resembled her real-life personality was the foodie freelance writer in Let's Eat 2 (2015), adding that she "didn't realize how much fun shooting a lively and comical drama could be." The drama was Seo's first attempt at romantic-comedy genre, in which she got good reviews and it became her career's turning point.



Her popularity grew rapidly after the hit romance comedy drama Another Miss Oh (2016), which she starred alongside Eric Mun. She was praised for her portrayal of such an ordinary and relatable character, and won the Baeksang Arts Award for Best Actress. Later in the same year, she starred in SBS hit medical drama Dr. Romantic alongside Han Suk-kyu and Yoo Yeon-seok. In 2017, Seo starred in the romance television series Temperature of Love penned by Ha Myung-hee.

In 2022, Seo starred in the SBS legal drama Why Her in the titular role of Oh Soo-jae, a lawyer-turned-professor and in the film Cassiopeia as a daughter who is diagnosed with Alzheimer's disease and slowly turning into a young child due to loss of memory.
