RE : Why did StayC lose steam after Asap?

When Asap arrived, Asap and Next Level revived 4th gen girl group digitals. But a year passed, Aespa has gone a long way ahead, new groups like Ive, Lesserafim came in stomping with sales and digitals, while StayC has not had a hit as big since and their sales stay below 200K, lower than Kep1er and Nmixx who have no hits. What’s stopping StayC girls from blowing up further?
