That's my personal opinion about charts, but rather than longevity or reverse charting, the initial performance is the one who shows if the public is interested in the group (as a brand). Red Velvet is pointed out as a group that the gp isn't always interested, but tbh, I think every era RV had the public interest because even if the rv last song wasn't their taste, they still listened to the new one and the song first day performance was good (the other days doesn't matter to this topic, chart performance isn't about RV as a brand, but about the song, even if a song charting high can make the brand stronger).
Same about aespa. Girls first day performance was actually pretty good, even more for a heavy song like that. The problem is the song, even if koreans gave a chance and tried to listen to it, they didn't like the cb (I loved it anyway)
Example of a group that lost gp interest? Kep1er. They never had a hit, but at least their older songs were actually listened. Giddy is one of my favorite releases this year and I'm sure SK would love it too if they gave it a chance, but We fresh damaged not only their gp interest, but their fandom too (they're selling less). If we name acts who used to chart high, Sunmi is a good example. She used to have hits, but now, her initial performance in the charts shows how the public isn't even giving a chance to her songs and she's usually out of top30 in the first day (Idk if it changed and she's charting better, I had a hiatus from kpop)
Obvious a song with mixed reactions can damage the public image and make the public don't listen to the next song (a popular group being out of top20 in the day of release is a bad signal), but we can only see how the gp reception exactly when the next song is released lol (Spicy showed how SK is still giving a try and listening do aespa songs)
Idk if it makes sense to anyone or I'm just really creative
