Sugar

Sugar (Hangul: 슈가, Japanese: シュガー) was a South Korean girl group formed by Starworld in 2001. The group's final lineup was composed of Ahyoomee, Hye Seung and Lee Ha-rin.

During their career, the group saw moderate success in the Korean music market and released multiple songs in Japan. Sugar's Japanese singles "Take It Shake It" and "Real Identity" were notably the theme songs for Kaleido Star.

The group officially disbanded after their contract with Starworld expired in December 2006, while only Ahyoomee maintained her career with Starworld until 2007 before transferring to the Starworld's affiliated label SM Entertainment.
