I have to disagree with this take.

Your obviously setting up yourself for disappointment if you think her growing from this situation is not going to involve Kirishima at all. From a writing stand point it makes zero sense at all. So she supposed to grow as a character without ever speaking to the guy who saved her, that’s just bad writing. (Unless she becomes ashamed to speak with Kirishima I suppose it’s possible she doesn’t interact, but whatever growth comes with this Kirishima situation will be on her mind.

I never like these takes I see from time to time on this subreddit where people are annoyed that a character has been involved in one development especially if it makes sense.

“Shouto has no importance outside of his dad

“Bakugou/Uraraka development with Deku bad...

Wether people like it or literally any character that goes through growth their is another character involved.

With a situation like this where Mina the usually brave confident girl freezes up, and has to be saved by Kirishima and your hoping Kirishima and her don’t speak about this at all is ridiculous.
