Listen but Ichi-san do be looking a snack in some panels 👀👀
On a side note, I agree with the others - maybe losing Narita, either to another guy or her taking initiative and breaking things off, will get this guy to get to it and properly end things with his fiance! It would be so interesting to see too, since this manga has mostly led us to see him the way she does: someone cool, aloof, handsome and seemingly the "leader" of the relationship, deciding when and where they'll meet with Narita waiting at his beck and literal call. She's already been thinking about asking him, all those unsaid questions in her head - if she grows as a character and takes charge for a change, I think it'd be so cool to see how Ichi will react, forced to either change with her or remain complacent to his loveless engagement.
