Early Life and Background
Keena was born Song Yu-ni on July 9, 2002, in Daejeon, South Korea. She trained under ATTRAKT ahead of the label’s plan to debut a globally minded K-pop girl group, joining what would become FIFTY FIFTY’s original four-member lineup alongside Saena, Sio, and Aran.
Career Highlights
Debut and FIFTY FIFTY’s Formation Keena officially debuted as a member of FIFTY FIFTY on November 18, 2022, with the EP The Fifty, under ATTRAKT. As main rapper and vocalist, her distinctive tone and confident stage presence quickly became a defining feature of the group’s early sound.
“Cupid” and Global Breakthrough FIFTY FIFTY’s fortunes changed dramatically with the February 2023 release of “Cupid.”
The retro-infused single went viral on TikTok and made FIFTY FIFTY the fastest K-pop group in history to enter the US Billboard Hot 100 and UK Official Singles Chart, doing so within just 130 days of debut — and made them the first K-pop girl group to crack the UK chart’s top ten.
“Cupid” ultimately reached Number 17 on the Billboard Hot 100, stayed on the chart for 25 weeks, and won K-pop Song of the Year at the 2023 iHeartRadio Music Awards for its “Twin Version” featuring Sabrina Carpenter.
Legal Dispute and Group Reorganization That meteoric rise was followed by genuine turmoil. In June 2023, all four original members filed a lawsuit against ATTRAKT, alleging the agency had failed to provide financial transparency and had neglected their mental health.
After a Seoul court denied their request to suspend their exclusive contracts, Keena withdrew her portion of the lawsuit in October 2023 and returned to ATTRAKT, while the contracts of her three groupmates — Saena, Sio, and Aran — were subsequently terminated by the agency.
Keena went on to attend the 2023 Billboard Music Awards as FIFTY FIFTY’s sole remaining member, a striking symbol of the group’s uncertain future at the time.
Rebuilding the Group In August 2024, ATTRAKT introduced four new members — Chanelle Moon, Yewon, Hana, and Athena — to join Keena and reconstitute FIFTY FIFTY as a five-member act.
The group returned with the pre-release single “Starry Night” on August 30, 2024, followed by the EP Love Tune and its lead single “SOS” on September 20, 2024, marking FIFTY FIFTY’s first release since the reorganization.
The group has continued releasing new material since, including the 2025 EP Love Tune: Rewired, and has expanded its global ambitions with international press coverage and a notable 2026 cover of Pink Floyd that drew attention from outlets like Variety.
Personality and Public Image
Keena has been widely praised by fans for her leadership qualities and confident stage presence, along with the hard work and dedication she’s shown in helping rebuild FIFTY FIFTY from a group of one back to a full five-member lineup.
