It's rumored that SM Entertainment's new rookie girl group aespa consists of 4 members - Winter, Karina, NingNing, and Aeri. (NingNing is Chinese, Aeri is Japanese.)
But while aespa will debut as 4 members, the group is based on a universe, which likely means that the universe will grow and add more members with each new story. This could be considered a unique take on the NCT concept of an unlimited number of members.
Be sure to look forward to more news on aespa, coming soon!
Nope nope nope they should've just debuted all of the girls they wanted to debut at once because now whatever girls they add later are just gonna get needless hate like Yeri and the new kids in NCT...
