KARA dropped their music video teaser for "When I Move", and fans noticed one empty seat in the teaser. 

"When I Move" is the title song of the girl group's 15th anniversary album 'Move Again' set to drop on November 29 at 6 PM KST. Shortly after the teaser reveal on November 27 at midnight KST, fans noticed one empty seat when KARA members sat at the table celebrating. Fans theorized that the empty seat is for the late KARA member Hara. 

Some of the comments are: 

"Six glasses and plate sets..."

"I miss Hara, hope she knows a lot of people still remember and miss her."

"I know this is sad, but you'll love their stage performance and the song. Don't feel too mopey."

"I went to the private recording for their music show and the song was really good. I loved seeing all of them back on stage."
"Hara ㅠㅠㅠㅠㅠㅠㅠㅠㅠ"
