I can't think of any remaining outs, assuming the child is indeed related to Haruka and not just a fosterling.
It would be pretty brave of the writers to take head-on the toxic idol worship culture in contemporary Japan and the horrifying backlash they face should they move one toe out of line, let alone commit career suicide by having a child out of wedlock while still working that 'pure' idol image in public.
