   Summary

   Phineas and the gang act their age. But for real this time.
   ***
   Are you an adult who grew up with Phineas and Ferb? Have you disliked anything about Act Your Age? Do you LOVE the show to bits but you're not afraid of looking at it more critically? Do you want some new hot takes from a seasoned veteran who has been in this fandom since 2007? If you answered "yes" to any of those questions, then this fic is for you.
   Rated M for mature themes such as childhood trauma, abuse and sexual attraction. But don't worry, nothing explicit happens, it's still Phineas and Ferb y'all.
   All illustrations were done by me. Hope you enjoy! <3
