[If Katsuki knew what Izuku was thinking right now, he'd probably get even angrier. That thought of how, when he does fight alongside someone, they always end up getting hurt somehow anyway. How he feels responsible for that, even if the person in question is a Hero too and knows and accepts the same risks that he does. It's never easy watching your friends take hits on the battlefield, but it's different with Katsuki.

He cares about him so much. A world without Katsuki isn't one that Izuku can fathom.]

[And yet in practice, well...Izuku's still working on that part.]

...I know you don't remember it, but...I wanted to thank you for being there for me anyway. It's thanks to you I'm even still here right now.
