The cast members of KBS2's 'Hong-Kim Coin' have officially made their K-Pop co-ed group debut!

The five member group made up of Hong Jin Kyung, Kim Sook, Jo Se Ho, Joo Woo Jae, and 2PM's Wooyoung goes by the name Unbalance. The group's first single, "Never", is the result of a 4-month-long journey, with the cast members pouring their hearts into every aspect of the process from recording their debut song, to learning the choreography, acting in the MV, etc. 

Produced by hit song-writer/producer Rado, "Never" combines elements of Jersey club, Latin pop, hip-hop, and dance, completing an "unbalanced", but still wholesome sound to fit the co-ed group's own sound and identity. 

You can watch the full MV for Unbalance's "Never", above! Meanwhile, viewers can also follow the Unbalance members behind the scenes during their eventful MV filming process on the October 19 broadcast of 'Hong-Kim Coin', airing at 8:30 PM KST.
