The rookie eight member mixed gender group named 'First' made their debut with the release of their digital single, "You Like Me, I Like You", last year, and they returned to make their debut performance on today's Music Bank after previously debuting on Music Core last year. Members are comprised of four girls and four boys: Lina (24), Sulhee (25), Jenny (21), Haji (26), Rakun (25), Han Saem (23), Rei (23), and Jung Hoon (21). Each boast an impressive background in their respective fields, such as Lina and Haji, who both won awards at the 2008 Miss Korea for Kyeonggi and Incheon.  Sulhee is a dance major graduate of Ihwa Women's University, while Jenny made prior appearances on EBS's "Ding Dong Elementary". Rakun was a leader of the b-boy team "MB Crew," while Han Saem and Rei are both former models, and Jung Hoon is a music major at Myungji University. Their title track is a dance remake of the 1985 hit by the duo "Hyun & Duk," and it features a modern remix of the hook melody to express the feelings between two lovers. Points to look out for in their choreography are the 'cupid dance,' 'shoulder dance,' and 'back hit dance.' Check it out below! Source + Photos: Newsis via Daum
