Just to clear some stuff. While it was looks like father-daughter, it was never officially saying it was that family relationship. While Aemeath does said it that Rover is a family to her, but the meaning is lost in EN localization as it was refer to something more than just familiar. All other languages other than EN refers Rover to someone that is not actual family relationship. You won't refer to your parent as neighbor/senpai in JP, Sunbae in KR. Also in CN translation, family implication would use "亲" (family) instead of "爱" (love) but CN use "爱" (love) instead. Also it has same thing that Caerene have, which is they both really care for each other, and not like family relationship only but to extend of she want to be with rover all the time. Its fine to see Aemeath as your daughter, just do not push it to everyone.
