Narrator is sitting at a desk, writing a script. "This is the story of a man named Stanley. He works in a big company pressing buttons everyday but one day something strange happened, No one had shown up to give him instructions, call a meeting, or even say 'hi'. Never in all his years at the company had this happened, this complete isolation. Something was very clearly wrong. Concerned and startled, Stanley got up and exited his office.."
(in this au everyone is a little, a caretaker, or a mix of both. When regressed the little in question turns to the age they regressed to physically as it is random though usually within an age bracket for example, narrator is a little in the age range of 3-7. Regressions last anywhere from minutes to a week, any longer and something is wrong. They can fight the regression but there is a long list of side effects including: insomnia, extreme irritability, changes in appetite, dizziness, fatigue, and even getting sick. Edit: regression is also physical meaning actually de-aged for the duration of the regression when I say toddler I mean toddler though littles have vague memories of their adult selfs and when back to adult form the memories are fuzzy like they had just woken from sleep though the emotional bond stays the same.)
