Prior to her explosive solo debut, G.NA has recently been garnering attention for her position as a backup dancer during promotions for 4minute HyunA's Change. It's normal for trainees' to be working as backup dancers for current members and groups, so seeing G.NA dancing to Change shouldn't come off as a surprise, it's just interesting to know. Check out one of HyunA's performances below, I'm sure you'll recognize G.NA right away. http://www.youtube.com/watch?v=ed6lcyfd3l0 [Many thanks to beccahuang for the tip]
