Jeong Se Hyun, known professionally as Saena, is a South Korean singer, dancer and former member of FIFTY FIFTY (피프티 피프티). She attended Haeundae Tourism High School but dropped out and later passed the High School Graduation Certification Examination.

During middle school, She was part of a dance club called "Lunatic" and was part of dance team "Horangdoongi" of Ho Dance Studio. She appeared on TV as a contestant on KBS's "Dancing High" as part of Team Hoya.

She made her debut in November 2022 as FIFTY FIFTY's leader, main dancer and sub-rapper with the mini album, “The Fifty”. The lead single, "Cupid", helped them become the fastest K-pop group to enter the US Billboard Hot 100 and UK Singles Chart (less than four months after debuting).

However, later that year, the members were involved in a series of legal disputes and allegations surrounding the group's contracts and treatment by Attrakt (어트랙트). Originally, all group members were involved, but Keena dropped the lawsuit. In October 2023, she had her contract terminated and was forced to leave the agency.

She then signed with Massive E&C (매시브 이엔씨) and is scheduled to debut with the company's new girl group by the end of 2024.
