On August 7, Red Velvet made the below posts on Instagram with moves from their "Power Up" choreography called the "wavy dance." Member Seulgi goes from labelmate to labelmate and gets them to do a dance with her!
She said of YoonA, "Wow. Unni, you follow so well," and YoonA responded confidently, "I'm Girls' Generation."
