cos younger fans have no worries and less obligations, so they spend their money on stupid things like 100 albums to get the photocard they wanted
so it is also stupid thinking you can`t cheat time. Those kids eventually get old and move one, and younger kids think people 5 years older than them are OLD PEOPLE... will only stan people closer to their age, aka teens
and yes, we all know most fanboys from teen girl groups are old men...but some are young too
