I lost a bet and now I have to write a sans x reader and I could choose which AU so I thought why not underswap. Nothing but the story is mine!!! I own nothing!!!

The title says it all. I might add more characters in the future idk I'm open to requests tho Characters: Izuku Midoriya Katsuki Bakugou Shouto Todoroki Eijiro Kirishima Denki Kaminari Hitoshi shinsou (late arrival) Tamaki amajiki (late arrival) Dabi (late arrival) Monoma (late arrival) Currently under editing at the time Characters and bnha don't belong to me Cover art doesn't belong to me
