After Park Jin-young revealed the name of his first girl group Wonder Girls in May 2006, the Wonder Girls were introduced through a TV show titled "MTV Wonder Girls". The first four episodes outlined the characteristics and profiles of each member. Shortly after selecting Yeeun as the fifth member, the Wonder Girls held their first showcase in the MTV Studio. They performed a cover version of "Don't Cha" by the Pussycat Dolls as well as original songs, including "Irony" and "" ("It's Not Love"). Sunye sang her version of Destiny's Child's "Stand Up for Love", while Hyuna performed a showcase of her dancing skills. The other three members—Yeeun, Sunmi and Sohee—performed a cover version of Janet Jackson's "Together Again".
