Yep, it wasn't very conclusive. So she went to study abroad and we are supposed to believe they will start dating when she comes back? I guess a proper epilogue chapter would have been a better way to end the manga.
That's my take, what with Heisaku's comment about "longing for days to grow long again" having replaced his normal infatuation. Instead of looking for the spaces in between he's looking forward to Fumio's return.
You can't be perfect if you can't cook. See every perfect male character ever, they're all great cooks. Case in point:
I'm a pretty good cook! Hooray! Step 1 Complete!
Harem Illogic indeed. Or can I somehow blame Stockholm Syndrome, with how he's the only male most of them have ever known? Either way, it's quite stupid... though of course, as if Nagasarete Airantou ever was anything else? I enjoy it despite its stupidity, pretty much. I mean, for instance, the fact that Ikouto still gets a nosebleed every single time he sees a naked girl, after 121 chapters of seeing them naked in almost every chapter (slight exaggeration there, but not by too much; he's the one who cares about such things, not any of them), probably, is so ridiculously impossible that I don't think I need to say any more... yes, he'd be used to it by now.
Running gag is a running gag, I suppose. I'm kind of curious as to what his wish was in its entirety, though. Could be on the way to a resolution for this.
...Maybe.
...doubtful.
