As much as it's starting to frustrate people, me included, I guess we really only have ourselves to blame, considering the manga does exactly what it says on the tin: there might be no plot progression, the protagonists might be acting weirdly for newlyweds, but it's nonetheless cute, every time, all the time.
I have to wonder how long the author can keep this up, though - are there enough readers who are content with reading this kind of material indefinitely...?
