[ Here it is. Another thing that he's done to Izuku. His behavior over the years has made it so that Izuku genuinely believes what the blonde's implied. Still thinks that there are parts of himself that Katsuki doesn't give two shits about. Still puts some of his self worth on the dismissive behavior demonstrated by Katsuki over the years. It's wrong. Everything about it is wrong and Katsuki absolutely hates himself for it.

There's only one person he's disgusted by. And it's not Izuku.

His own grip relaxes. There's a lump in his throat that he swallows down. No. No, he's not going to let this own keep going. ]

Never actually hated you... And I.

[ Do it, Katsuki. You've already apologized in front of everyone. Bowed your head. You can say this now too. ]

It was always me. Only said those things because you were already so much better than me and I was too much of a shit to realize that the person I was angry at was me. It was never you.

[ When he looks back up at Izuku, it is because Katsuki is actually the crybaby. It's him. Because he always has this habit of getting all emotional in front of this boy. Every single time they fight like this. Every single fucking time. ]

So nothing you've ever said or could ever say would make me hate you.
