Here’s something to butter your bagel.
I was friend-zoned a lot, which means I got to see the veneer come off more than most.
One problem with the veneer fooling the adults is that the adults forget that it's just a veneer (if they ever knew), and so the girls who get good at it are given a lot more autonomy* with regard to their relationships than they probably should. Parents fear the violent rapist or the super-possessive / abusive boyfriend, and forget the ones that aren't working physical or obvious emotional damage.
*Autonomy might be a bad word, since I don't want to imply that a teenage girl should not be allowed to manage her relationships with boys.
