   Summary

   Katsuki Bakugou is an alpha. He’s always been an alpha. He’s supposed to stay an alpha.
   So why is he suddenly nesting?
   Why does praise make his throat tight? Why does touch feel like it’s burning through his skin? Why does he keep catching himself wanting to lean into Izuku like he belongs there?

   And once Katsuki starts changing, it isn’t just his body that shifts — it’s his whole world.

   Or

   Izuku has been accidentally bitching his boyfriend into an omega without realizing, and Katsuki is going crazy over this new revelation
