Five-member South Korean boy band formed by Well Made STAR M, the company that houses such actors as Ha Ji Won, Kim Seung Woo, Choi Jung Won, and Lee Jong Suk, in 2011. The group consists of Woosang (Leader), Aoora, Joowon, Hoik, and Kimchi. With their 100th days since debut fast approaching AA has already gained such nicknames as resume-dol, standalone idols, and Gaecheokdol. Aoora was the first to join the group. Looking for a company he could work with and make music he decided on Well Made STAR M with 100% confidence they'd help him achieve his dreams. Aoora then brought Woosang to the group, asking him to do the choreography for his music. The company then later added Juwon, Hoik, who had aspirations to be a singer and moved from Busan to Seoul to do so, and Kimchi, who'd quit learning the piano and clarinet to pursue his dream of becoming a singer.
