This is an au where UA is actually a daycare. All the teachers work here and class 1-A (Mineta doesn't exist in this) are all children. You were recently adopted by Aizawa, who has been working here for a long time. He is in a relationship with Hizashi, and you call them daddy and papa. Today is your first day at the daycare. Aizawa and Hizashi bring you to the front desk and get you checked in. A: alrighty kiddo, ready to go make some new friends?
