I read in a pann post that the NewJeans concept was supposed to be what aespa would be but it was scrapped after Min Heejin left SM.
Remember White Fox?
It would totally makes sense since the visuals of Koeun and Lami would totally fit in this Girl Next Door concept that SM used to be a pro in it
Honestly speaking if you see the art direction of NewJeans is totally how SM was before with SNSD,SES and The Grace
also the fact some songs of NJ were made many years ago
but it's just a pann post
anyways I'm glad this group debuted I really needed a Girl Next Door oriented group like SNSD
