I agree. The thing is, at first I though it was the same characters but different story as in, in the adult fan service version potato wasn't raised by wolf. Which is still weird if you think about them being family in the original but I could ignore that.
But it's actually that in the adult fan service version potato was still raised by wolf but they ended up in a relationship/ crush situation (even if only one sided). That part truly weirds me out.
It should've been a complete AU or what you call it IF at all...

they are so perfect as found family i really hope the author stop pushing the "fan service" i really dont care if in that version they are both adult or if its one sided in the puppy part. its just so fing weird when he spend most of his childhood seeing the wolf as his mother.
i know there gonna be people who ship them because humanity is doomed but what i really hate is how the author play part in this yet has the audacity to said its just fan service and non canon in his weibo.
