what if deku's quirk forced him to be fused with his twin brother? They met Katsuki after moving so he never knew about the other brother, he was still bullied but the reasons are to be explained in further into the book. Also Katsuki will not bully Izuku Disclaimer!! The start of this book may seem to be incest but it is not... there are a lot of plot twists. one ship!! I barely ever read an op Deku book with one consistent ship so here we are!! I own nothing except the damn plot.
