@sun One of my favourite manga is Renai 3D Debut, unfortunately incomplete in scanlations. It is an auto-biographical story by a woman who married a colleague. Both of them are manga authors... And the guy became famous for a manga about a school that banned wearing underwear. Apparently they changed nothing and the dynamic duo are presented with their real names (but their editor is not - at least someone got privacy).
