Aespa was given 3 Grand Prizes, and Gidle was thrown a bone.
MMA was the only Grand Prize (it was not considered to be a major award until 2017) to Beast, the only Cube act which won some kind of Grand Prize, now called Highlight (no longer Hi5hli5ht because of Yong Junhyung's antics).
That led to Cube winning its first real Grand Prize and also led Jeon Soyeon to remain in there for the time being.
Anyways, if Melon and Kakao had respected IU an iota it would have given her the Album of the Year Grand Prize, but it didn't giving all three major awards to aespa, lifting it at the level of BTS, the only other act which had done so.
Which basically means Melon and Kakao telling IU that her time is up, time for her to pack up her belongings from Korean pop and head to the retirement home.
The 2nd Generation was born in 2006 with the debut of Big Bang, had its final moment of glory in 2021
when IU managed to wrest the Artist of the Year award from BTS and leading it to an inexorable course of collapse,
but the defeat of IU, the last standing of the 2nd Generation, by the hands of Bibi, who showed up at the award to commemorate that despite of the fact that she is filming some drama, finished it off.
The last challenge is the gallup polls, which aespa traditionally did not do well in there. New Jeans was all over in the news, and IU always had a 'core' voting bloc, so there is a chance that aespa will be beaten there, but if aespa wins that one the 2nd Generation finally ends.
