K-pop girl group Fifty Fifty is making a comeback in September, now as a quintet with four new members joining original member Keena. The group's agency, Attrakt, held auditions to find new members for the group's new phase and finalized the new lineup in April. Originally scheduled for June, the comeback has been pushed to September to allow for album quality and global marketing preparation. The group plans to introduce a single that highlights their unique musical identity before their official return. Fifty Fifty originally debuted as a group of four on February 24, 2023, and achieved significant success, with their first single "Cupid" reaching No. 100 on Billboard's Hot 100 chart. However, following a legal dispute over contracts, three members left the group in October last year, leading to the search for new members to revitalize the group for their upcoming comeback.
