This was a cut from Kara’s SelfCam segment shown on 25th August.
Kara were filmed backstage on MNet M! Countdown on 24th July waiting for their turn to perform. The Wonder Girls were performing “So Hot” while Kara was waiting for their turn. As the Wonder Girls finished and left the stage, they passed by Kara and they greeted each other along the way. With the exception of Sun Ye who seems to be in a hurry, the other 4 Wonder Girls interacted with Kara as seen from the screencaps (So Hee bowed at the end).
Seung Yeon and Ye Eun are friends and go to the same university (different faculties). Ye Eun thanked Seung Yeon in their “So Hot” single album.
Kara leader, Park Gyuri and Yoo Bin have been close friends since high school. Yoo Bin also thanked Gyuri in their album.
Gu Hara and Sun Mi are friends who met during their auditioning days. Hara tried out for JYP Entertainment but failed. But she’s in Kara now.
Here’s the video if you think that was not enough.
