EvoL (Korean: 이블) is a five-member girl group from South Korea created by Cho PD under the label Stardom. They released their debut EP and music video for the track "우린 좀 달라 (We Are A Bit Different)" on August 10, 2012.
In summer of 2015 rumors started to appear that Say's contract with Stardom had expired and that she had left EvoL while still remaining with Stardom Entertainment, and would redebut as a solo artist. Cho PD and Stardom Entertainment never responded officially to these claims, which were spread online by fans (who also alleged favoritism from Cho PD on Say's behalf, claiming she had been given special treatment compared to the other members). Say later began a solo project under the name "Saay Choreography".
In August 2015, it was revealed that Yull, Hayana and J-Da had had their contracts terminated (without their knowledge) during Stardom's merge with Hunus Entertainment, thus effectively disbanding the group.
