The story in this game actually knows only one meaningful course: father and daughter must come together. Anything else would probably be real life, but not what you'd expect in this type of game.
And it's almost a little weird that some people here wish for this path in the game (the father is just a caring father) and then don't want to follow it, so that it's kind of more taboo, really?
At least I can understand the developer not even including such a path, which hardly anyone follows, because it takes far too much effort.
So, let's just hope this is where the story from Our Fate finally comes to a meaningful ending. And by the way, I really don't understand why the Our Fate developer prevented this development team from finishing the original story (see separate thread:
https://f95zone.to/threads/our-fate-remake-dev-thread.91509/).
But ultimately that led to this new game that will probably be more exciting than the original Our Fate story.
