With Aespa leading the pack in the 4th gen now and bringin in a lot of fans.
It can boost public interest into some of SM's older girl groups.
With Aespa in the group, they can bring in younger fans and have them embrace some of the older gg's in the line-up.
Girl groups seem to always have a shorter life span than boygroups and this could potentially expand them by keeping some of the members busy and have more success with newer comebacks.
I'm super excited to see Taeyeon and Hyoyeon join this line-up since im a huge sone, and with Aespa's current succes. it can easily put some of that spotlight on Girls Generation and Red Velvet for their future comebacks!
