IMO, it's too much. Less is actually more sometimes.
Announcing over a month in advance, surprise b-side release, SMCU Ep. 2, Life's Too Short music video, L.A showcase for two days, late night show performance, teasers, and THEN, finally, a mini-album, of which people have already heard 3 songs? Overkill. No one can argue that Aespa is not promoted enough. But SM is not building hype well, instead they are kind of overwhelming the fans and casual followers of the group
A much better roll-out plan would have been doing an early June comeback instead. They could have dropped the Girls announcement immediately after Coachella performance while the hype was still high and then opened pre-order the next week. Then scrap the Illusion release, since they pretty much wasted the song. Scrap Life's Too Short MV and US promotions too, since this song will do nothing for Aespa's career. Drop the SMCU Ep. 2 a week and a half before the comeback (and put more of the actual girls in the video) and then 10 days of teasers before the MV.
