Chapter Text
Hi! Welcome to my work! This first chapter/section is headcanons I wrote that I will be working off of for the characters :> If you have any additional headcanons, feel free to drop a comment!
I didn’t use every student in 1-A, just those I’m more familiar with/comfortable writing about. There are littles, caregivers, and “flips” (both little and caregiver/babysitter). “Subdrops” refer to times where the little drops below their usual age range. If you are unfamiliar with the classification AU, I recommend looking into some (sfw) research! Essentially, everyone gets an assigned role of the above mentioned labels. They fit with their personalities and settle into the roles naturally (usually). ^^
Semi-beta read. Will revisit for typos later. Will also add Izuku’s in shortly. Enjoy!
