Both aespa and Illit were deeply struck by the tsunami called APT.
In one single shot, the 4.5th gen ended, and while aespa kind of held on, the 4th gen also suffers a lot.
With APT the resurgence of the 3rd generation starts, and with the return of bP and probably bTS next year, the 4th gen's heyday ends.
And all these 4.5th Gen, formerly 5th Gen but now no longer can be called as such since Illit failed to dislodge aespa, let alone Rose, acts have now lost their initiatives- not only they have to beat the 4th Gen, they now also have to defeat the 3rd Gen!
With at least 2 more years of 3rd Gen rule in KPop, how would the 4th Gen and 4.5th Gen would cope? The 3rd Gen, after the resurgence of 2nd Gen, fought with Exo, but with the fall of NJ there is no clear leader of 4th Gen and aespa, the strongest of them, was already vanquished by Rose.
Will the 4th gen , and 5th Gen now renamed 4.5th Gen, recover from this major defeat? Maybe but the journey will be long and ardrous.
