Seo Ju-hyun (Korean: 서주현; born June 28, 1991), known professionally asSeohyun, is a South Korean singer, actress, and songwriter. She debuted as a member of girl groupGirls' Generation (and later its subgroupGirls' Generation-TTS) in August 2007, which went on to become one of the best-selling artists in South Korea and one of South Korea's most widely known girl groups worldwide. Seohyun released her first extended playDon't Say No in 2017. She leftSM Entertainment later that year, although she remains as a member of Girls' Generation.
Seohyun was born Seo Ju-hyun on June 28, 1991,[1] inDoksan-dong,Geumcheon District,Seoul, South Korea,[2] and is the only child in her family. Her mother was a chairwoman at a piano school, and Seohyun was taught how to play piano as well as violin and traditional Korean drums in her early childhood. She also learned horseback riding and skating as a child. Her parents did not encourage her to become a celebrity, but Seohyun credited them as the ones who helped her choose her career path by letting her experience different things.[3][4] As a fifth grader, Seohyun was discovered by a talent scout while riding in a subway train. She sang children's songs for her audition atSM Entertainment and was accepted as a trainee.[4][5] Seohyun citedBoA,S.E.S andFin.K.L. as her main influences to become a singer, expressing "I thought it was cool to show and communicate the emotions through songs".[6]
Seohyun graduated from Jeonju Arts High School in February 2010.[7]
She attendedDongguk University, majoring in theatre acting, and graduated in August 2014, receiving an achievement award at the graduation ceremony.[8] Her fellow Girls' Generation member,Yoona, attended the same university.[9]
In August 2007, Seohyun made her official debut as the youngest member of girl groupGirls' Generation.[10] The group gained significant popularity after the release of their hit single "Gee" in 2009.[11]
Seohyun's early solo work mostly involved songs recorded for side projects and original soundtracks. Although they did not achieve much commercial success; her duet titled "JjaLaJaJJa" with veteran singerJoo Hyun-mi earned a "Trot Music of the Year" nomination at the2009 Mnet Asian Music Awards.[12] In 2010–2011, Seohyun appeared inMBC's variety showWe Got Married 2, alongsideCNBLUE'sYonghwa. They played a make-believe couple, portraying what life would be like if they were married.[13] In addition, Seohyun was cast as voice actor for the Korean-dubbed version of animated filmDespicable Me (2010) and its sequelDespicable Me 2 (2013), together with fellow memberTaeyeon. She voiced the character of Edith, who is known for her rebellious attitude.[14][15]
In April 2012, Seohyun, along with fellow members Taeyeon andTiffany, formed a Girls' Generation subgroup namedTTS.[16] Their debutEP,Twinkle, met with much success and became the eighth highest selling album of the year in South Korea.[17][18][19] The subgroup went on to release two more EPs:Holler (2014) andDear Santa (2015).[20][21] Besides contributing her vocals to Girls' Generation and TTS songs, Seohyun began to become more active in lyrics writing. She co-wrote the songs "Baby Maybe" and "XYZ" (I Got a Boy, 2013) and was credited as the sole lyricist for "Only U" (Holler, 2014) and "Dear Santa" (Dear Santa, 2015).[20][22][23]
In 2013, Seohyun debuted as an actress when she was cast for a supporting role inSBS's dramaPassionate Love. She played Han Yu-rim, a veterinary student and first love of the male lead character. Director Bae Tae-sub said Seohyun's persona "perfectly paralleled that of her role" and "her understanding and expressiveness of the character exceeds those of a rookie actress".[24][25]
Seohyun, self-described as someone who likes both singing and acting, began to develop an interest inmusical theatre. She named musical actressOck Joo-hyun, who later became her mentor, as her main influence. Although she had wanted to be in a musical for a long time, she rejected casting offers because she felt unprepared.[26][27] In January 2014, her wish was fulfilled as she accepted her first musical acting role. Seohyun made her theatrical debut in the musical,Moon Embracing the Sun, which was adapted from the novel of the same name.[28] Seohyun played the lead role, Yeon-woo, the daughter of a noble family who has a love relationship with both the King and his brother.[29]
Seohyun performing in theGone with the Wind musical in 2015
In January 2015, Seohyun was cast in the role ofScarlett O'Hara in the Korean version ofAutant en emporte le vent, a French musical based onGone with the Wind.[30] She received encouraging review for her performance. Seon Mi-gyeong ofOSEN said that while Seohyun's performance cannot surpass that ofBada, who shared the same role, her "fierce voice" complemented and successfully expressed an arrogant Scarlett O'Hara.[31] Kim Hyun-joong ofSports Chosun noted Seohyun's occasional "clumsy" acting, but compared her to Ock Joo-hyun during her rookie days and said that "her ability to bring emotion through song, the most important part of a musical, rivaled that of a veteran actor. Despite a short career, she endlessly showed us various colours and peculiar charms of a woman's life."[32]
From February–June 2016, Seohyun was cast in the Korean version of the musicalMamma Mia. She played a character named Sophie, a 20-year-old bride-to-be, who hopes to find out who her biological father is on her wedding day.[33][34] Kim Geum-yeong fromCNB Journal commented on Seohyun's improvement from her prior musical performances, praising her "natural acting" and "daring side" while Park Jeong-hwan fromNews1 claimed Seohyun's performance made the musical "all the more entertaining".[35][36] Seohyun next played supporting roles in Chinese romantic filmSo I Married An Anti-fan and SBS's historical dramaMoon Lovers: Scarlet Heart Ryeo; the latter earned her a Special Acting Award at the2016 SBS Drama Awards.[37][38][39]
