I kind of like the relationship dynamic they have as far as romance fiction goes, when it's going, but the author is a lot of the time apparently more interested in thinking up ecchi scenes for every other chapter.
Well, more recent chapters seem to be tilting a little less towards their entire raison d'être being cheap fanservice moments, so that's nice, at least. I still have a distinct bit of that "it's a shame quite so much of the point of this seems to be ecchi" feeling, though.
