Fans babying their biases, especially when they’re adults, is one of the weirder sides of Kpop. It’s just something creepy about seeing edits with idols in their mid-twenties with kids songs playing in the background.
Now for groups with really young members and a youthful concept this is slightly less weird imo so mostly thinking of groups with all adult members.
I’m gonna say Shawols with Taemin and Armys with Suga and maknea-line (especially Jungkook). Now Taemin is the forever maknae and it’s kinda in the manual but as he gets older fans babying him just comes of as more and more out of place. And I swear I see more clips and Armys talking about Suga and Jungkook and how they are “adorable cuties” with “squishy cheeks” or something along those lines than all other idols combined.
