“Orange Caramel (오렌지 캬라멜), is the first sub group formed from the South Korean pop group After School. This sub-unit was formed with the third generation members: Nana, Raina and Lizzy. Orange Caramel’s concept is more lighthearted and sweet unlike many girl groups that have taken on darker, sexier concepts.

They debuted on June 16, 2010, with the single “Magic Girl”. They released their debut mini-album The First Mini Album on June 21, 2010. The album was a commercial success, peaking at #2 on the Gaon Chart and the lead single “Magic Girl” peaking at #18”. – Wikipedia
