yes I'm back here to kick my own ass by re-reading this I want them back !!
I don't even think Kanefumi thinks Asahi is straight, because the emphasis was on Asahi's feelings in the relationship not actually being romantic love. Not only was Asahi younger than he expected, Asahi was pretty open on what had happened in previous relationships, and how they were trying this out because it felt like it might be different. Based on Kanefumi's previous relationship experience and the social idea where "if nothing really matters to you you should just do what's easy and normal" it is annoying dsfjdsjhfg but it makes sense for him to try to nudge Asahi on the other path before something happens to either of them or Asahi's other platonic relationships. And while the conversation was mostly one sided I think the page four "unless that'd be a problem for you" was his open rebuttal moment of "now if i'm wrong with this assessment..."
But skdfhdkjfshjkdhfklsh as an aroace-flavor person myself the "you don't actually love me" was devastating and Asahi's stunned and confused "well I don't really know where the line in the sand is so like...as long as we're doing the same things...it's...fine though I don't like losing this label for some reason?????" was very so realistic lol, but unfortunately seemed to totally confirm things for Kanefumi.
I hope they talk again and clear this up !!! Maybe Asahi is grey-aro or demiromantic and he can make his case to keep the relationship or maybe he will decide it's fine like this until it's 20 years later and he has an epiphany about the one that got away!
Either way PLEASE LET US SEE IT 46 !!!
See, I agree and like your assessment because that's ALSO another element of how I felt while I was reading it. I don't know if I can express this point but: Asahi decided to be in that relationship of his own free will. Kanefumi (thanks for reminding me of his name) is trying to do him a solid by giving him an out/freedom. But to get to that point, he is deciding that Asahi's reasons for being in the relationship aren't good enough (not automatically unfair) before confirming what those reasons are (much less fair).
Kanefumi knows Asahi is wishy-washy. It's logical to assume someone who can be pressured into dating people they don't want to date can be pressured into breaking up when they do not want to break up.
Kanefumi does not have to put up with that passivity. However, if you come to someone you are close with, and you bring up a serious topic like this, while pushing one specific outcome, the person you're talking to is very likely going to cave to what you suggest. Especially when it's out of the blue like this. And that applies to people who aren't wishy-washy push-overs.
The break-up reminds me of the earlier conversation Short Lesbian Girl had with her crush's boyfriend. One person is assuming what will make another person happy, or make their life easier, without taking their actual feelings or autonomy into account. Except Kanefumi is doing it from a savior-complex/anxious-avoidant angle.
Probably over-thinking this. I'm bad at guessing what authors are trying to show in their series. Good arc so far.
