This is isn’t my business but most people ship them because of how close they were when they were kids. So they don’t ship them being abusive or anything, but them being good to each other. If Katsuki wasn’t praised for every little thing he did as a kid because of his quirk, he would have stayed Izuku’s friend but he was lead to believe that only people with quirks matter by his teachers and classmates.
