Mini bio
How it started.
Born Seo Ju-hyun in Seoul, Seohyun entered SM Entertainment’s trainee system in 2003 after being spotted on the subway. She debuted with Into the New World in 2007 as the youngest member of Girls’ Generation. The group’s 2009 hit Gee helped bring her to a much wider audience.
Finding her own voice.
In 2012 she joined Taeyeon and Tiffany in Girls’ Generation-TTS. Her own seven-track EP Don’t Say No arrived on January 17, 2017, with lyrics by Seohyun on six songs and an Eric Nam duet, Hello. The record gave fans a closer look at her songwriting and R&B-pop sound.
From songs to characters.
Seohyun expanded into television with Passionate Love in 2013 and musical theatre with roles including Gone with the Wind and Mamma Mia! Her screen work includes the Netflix film Love and Leashes, the historical action series Song of the Bandits and the 2025 fantasy romance The First Night with the Duke.
Still learning.
In 2026 she brought another musical interest to the stage, appearing with the Sol Philharmonic Orchestra as a violin soloist. She had studied the instrument as a child and returned to it in 2025.
