I'll be honest: I'm not liking this ending so far. Not only is it drawn out unnecessarily, but it's made as if this is some grand proposal more than it should. Even if it effectively was (I mean, young single religious friend groups exist), does every friend NEED to find out BEFORE? Like, that's just not classy.
At least Nene didn't give EACH their own chapter. In fact, I would have liked if the Kubo and Shiriashi families (or at least the mother) got a chapter and nothing more.
Classic case of the haphazardly-ended manga. But much like "Erased", it was a good one overall.
