In 2007, Jiwon was set to debut as a member of Five Girls, a five-member girl group under Good Entertainment. However, due to financial issues, the group was disbanded before they could debut. Other members of Five Girls included UEE, Yubin, G.NA, and Jun Hyo Seong.
Shortly after Five Girls disbanded, Jiwon joined Core Contents Media to become a member of the then-upcoming group T-ARA. However, she left the group before its official debut despite recording a song and music video with them.
