[Once Bakugou starts pushing, Izuku lets him shove him away, leaning back on his heels so he isn't bruised by the force of it. But that doesn't mean his expression is any less hard right now, because despite Bakugou's yelling he's still firm on what he just said. Even with Bakugou raising his voice, making it a bit...dangerous for other people who might overhear.

Bakugou had been neglecting to tell him he was getting those kinds of urges, which meant...the virus was spreading a lot faster than he'd calculated it might.]

It's not going to be like this forever, okay!? It can't be! They'll find a cure, they'll find a way to fix everyone, somehow!

[Part of him doesn't believe his own words, but he just...he can't give up.

If he gives up on Bakugou now, there's...just no hope for him to even continue to live any longer.]

You don't mean to tell me that you of all people are giving up on yourself! You can't be, Kacchan! Not you!
