Why are StayC so behind other 4th gen girls in sales (besides company privilege)?

Aespa’s already had a million preorder on 2nd album, Lesserafim, Nmixx pulling 300K+ on debut albums, Ive 500K second album. Stayc has as many or more hits than those groups yet they are on their 4th album and their sales is less than 200K. Being from a smaller company is one reason, but what are some other reasons that hold back their sales?

they don't appeal to the ifans and with that I mean western and SEA fans (big buyers) and the most important ones, japanese and chinese fans, the biggest buyers for most ggs. they mainly have their kfanbase which is strong enough to win against itzy in live votes on music shows. but I guess their content and vibes aren't that attrractive for fans outside korea + the small company and no previous fandom disadvantage

their success is overblown by people, they do mediocre numbers in international things, they don't have one single song over 100m in either spotify or yt, at most 60m. Their charting in sk is also very overstimated, ASAP only peaked at 8, and it hasn't cross the 4m uls in melon, not over 100m streams either and their index points are barely 470m. So bad flopped, so did Stereotype, not even 200m points and Run2u doesn't have enough longevity for peaking one spot higher than ASAP, and even the peak in points was ASAP. They are just not that big and people got their sales big now due the success stans.

too many competitions

Being from a small company that has no brand value is 90% the reason.

Their concept could also be a contributor. It's less mature than concepts those other groups execute. It's more on the high teen side.
