Classification Day

An Oumota Classification fanfic! A Non-Despair AU mixed with a Classification AU, where everyone gets an assigned role; Caregiver, Babysitter, Switch, Neutral, or Little! This book is Non-Kink, meaning that it only involves Age Regression, which is used as a coping mechanism. Please do not treat this as being any sort of kink! This is a SFW book!
