RV have always been close to NCT. Yeri especially is friendly with literally half the group, Wendy is friends with them too, Joy looked out for them a lot in their rookie days. Yeri is also still friends with Goeun an SM rookie girl that was a potential member in Aespa lineup, but never mentioned any Aespa girl. RV never congratulated Aespa either.
However Joy takes a pic with Rei from IVE, uses IVE Eleven lyrics as her IG caption, follows StayC on her private IG but not Aespa, mentions publicly Itzy and StayC as the rookie girl group she likes.
Someone here pointed it out very well : Aespa are like RV’s little sisters that have it better. RV get a 10 dollar budget for Queendom but Aespa get the best teasers in Kpop for both Next Level and Savage. Aespa get vlogs, promotion in NYC less than a year after debut, a lot more content than RV ever had. ( they had to wait 3 YEARS for their variety show and barely had any content in general )
Their debut was very random and during a time where RV was in a drought.
Also, Aespa sell almost two times what RV sells.
