Re: the moon... people, they've been doing that whole 'showing the moon after something that'd normally be flags' shit for most of the manga. It hasn't meant much of anything. Stop spazzing out. This is basically just a fluffy manga. I mean, that might change in a hundred chapters, but if it's still mostly the same adorable manga 80 chapters in, I seriously doubt it's going to be all that different in the next 80 or even beyond.
They keep revealing little tidbits at a time, they keep showing the Yuzaki couple becoming more and more comfortable showing affection with each other. There's progress. It's gradual, but it is still progress.
Just when people think drama is about to happen, it turns out to not be all that serious and turns out to be more amusing stuff. This is the way.
