I wouldn't worry about it. It's just people taking things way too far. They interpret curiosity regarding how Ayu feels about having children and if she ever will, as fans "expecting" her to have a child because that is her "job" as a female.

I'm curious as well if Ayu has a desire for a family, mostly because I am not sure she has ever mentioned it. But similar to what you said, it's her choice if she wants to and neither choice is bad.
