I can see this ending, unless the author manages to make it into a proper harem manga, plus there's the thing with the doctor being a witch that they don't know about.
@lenteraneko That nurse was talking about how the hormones needed to produce those diamonds were gushing out, so... one more arc, at least, about that conversation and the fallout of it, considering what the two are doing?

Probably the story will shift focus on someone else; for example, a random mini-sized high school girl and a BIG GUY. That's what usually happen when the main couple characters have finally "done it".
