History

2007: "Debut"

Kara debuted on March 29, 2007 with "Break It" on M! Countdown, from their first album The First Blooming. Two music videos, "Break It" and "If U Wanna," came from this album. Because of their similarity to Fin.K.L and the fact that both groups were signed to the same company, the two were often compared; in response, Kara stated that they regarded the comparison as beneficial and inspiring. As the album was not a commercial success,member Han Seungyeon participated in many TV variety shows in the following months to keep Kara as a group recognizable to the public.

2008-2009: "Group image and line-up changes, rise of popularity"

The group was scheduled to have their comeback in March 2008 with their second album. However, Kim Sung-hee left the group suddenly due to parental pressure, as her participation in the group was contingent on the maintenance of her grades. In response, DSP stated that the second album would be shelved and replaced by a mini-album to come in May; in addition, two members would join the group. The two new members were eventually revealed to be Goo Hara and Kang Jiyoung. KARA made comeback as a 5-member group on July 24, 2008 with "Rock U" on M! Countdown.

Netizens made it a "hot issue", but Koo Hara received comfort instead of criticism from the public.

Park Gyuri attributed their popularity increase to their "pretty but natural" appeal, while media reports gave credit to the band finding its own identity and to older male fans, most notably singer Shin Hae-cheol. Due to their increasingly hectic schedule as their popularity rose, a few of the group's members were taken to the hospital on December 19 after a KBS Music Bank rehearsal for cold and exhaustion.
