She is best known as a former member of the girl group S.E.S., which went on to become one of South Korea's best-selling artists. Following the group's disbandment in 2002, she subsequently left SM Entertainment and released two solo studio albums.

Eugene made her debut with S.E.S. in 1997. S.E.S enjoyed tremendous success, becoming the top-selling K-pop girl group, until TWICE broke their record in 2019. The group broke up at the end of 2002 after Bada and Eugene parted ways from SM Entertainment, while Shoo stayed with SM Entertainment until 2006.
On May 28, 2016, Eugene with S.E.S. members Bada and Shoo attended a charity event, Green Heart Bazaar.

On January 2, the special album of their 20th anniversary debut Remember was released. The album consists of double lead singles.
