the male voice harmonizing in the pre-chorus and that "aaaaah" before the bridge is yoo young jin (he is in the album credits as background vocals both in aenergy and savage)
We know but he is not a part of aespa, this is for aespa only so people will know who in the members were most likely to do harmonization aside from yyj
ningning is being counted for the "ahhhhh" behind the "savage" (male voice) - maybe it's not even ning but rather giselle but still, the creator isn't saying ningning sings the savage part but what's behind it
