Would you all kill me if I say one of my rare ships is Melissa x Katsuki? It doesn't have to be necessarily romantic, I like it even as platonic.
Just think about it. They're both very smart, all might fans, and Katsuki probably has been interacting with her a lot because of the billion dollar suit so that's how they know each other. Both of them number one in their own fields (talking about skills not that hero popularity ranking🙄) and strive to be the best. And from what I saw, Melissa seems to be a bit of perfectionist as well. And ofc the contrast in personalities is so funny. And Katsuki is always so much involved with his own hero suit design and take care of its gauntlets a lot. So he might have some enthusiasm or knowledge about her line of work.
Also I have this hc that Melissa suggested to Katsuki he should change his gauntlets for a more efficient flow and that's why he has changed it to the ones she designed, when he went pro.
