Kara (South Korean group)

The group started off as a quartet with members Park Gyuri, Han Seung-yeon, Kim Sung-hee, and Jung Nicole. On March 29, 2007, Kara debuted on Mnet's M Countdown with "Break It" from their first album The First Blooming. Their debut song displayed a strong female image and R&B sound. Other singles from the same album were titled "If U Wanna" and "Secret World". Music videos for the first two singles were created.[16] Although their album was acclaimed by critics, it was not well received by the general public and was overshadowed by other girl groups who debuted the same year. All promotions for their first album ended in the summer of 2007. In August 2007, the group came out with a documentary on M.net called Kara Self Camera which showcased the group, their talents, and the relationships they had with each other. The first season debuted on August 8, 2007, and ended on December 12, 2007, with over 15 episodes. In the following months, member Seungyeon continued participating in many television variety shows to keep the group's name recognizable to the public, as their first album was not a commercial success.[17]

Comparisons were often drawn between them and their senior labelmates, Fin.K.L, because of their similarities in style and concept as well as the fact that the two groups were signed to the same label. Additionally, each individual member of Kara was paralleled to a member of Fin.K.L. In response to the comparisons, the members of Kara stated that they regarded the comparisons as beneficial and inspiring.[18]

The group was scheduled to have their comeback in March 2008 with their second album, however, member Kim Sung-hee suddenly announced that she would be leaving the group and retire of the entertainment industry. She first announced her departure from the group due to her parents pressure, and hence she failed all of her college exams she made her decision to leave in order to focus on school and education. In response, DSP stated that the second album that was recorded would be shelved and replaced by a mini-album to come in May; in addition, two members would join the group. Auditions were held, and the two new members were eventually revealed to be Goo Ha-ra and Kang Jiyoung. The group made their return in the music industry as a quintet on July 24, 2008, with "Rock U" on M Countdown. Their first mini-album titled Rock U was released the next day. They made their comeback with the "cute" and "playful" image which was the complete opposite of the group's original image from their debut. The second season of Kara Self Camera premiered on August 18, 2008, which chronicled how the group was adapting to their two new members.[19]

On November 29, 2008, DSP released a teaser video for their upcoming single, "Pretty Girl", which received over 40,000 hits within 12 hours.[20] The full video was released on December 2, 2008, online and was positively received by the public.[21] The EP, Pretty Girl, was released on December 4,[20] embodying a "fun-party" concept.[21] The group began promoting their comeback on all major music shows on December 4, 2008, starting with M!

Park Gyuri attributed their popularity increase to their "pretty but natural" appeal,[25] while media reports gave credit to the band for finally finding its own identity in the music industry since the group's debut[26] and to older male fans, most notably singer Shin Hae Chul.[27] 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 Music Bank rehearsal for cold symptoms and exhaustion.[28]
