Okay, so this AU is where Deku gets captured when he's a kid by someone, and becomes a lab rat. Class 1A is on a field trip to a lab, that happens to be the same one as where Deku is. Deku calls Bakugou, "Kacchan" and Bakugou calls Deku, "Deku". Hope that helps a bit, also I don't really have any ships, but if something happens its not my fault, sorry if something happens tho. Anyways! Have fun!
