Where did all this hate for F come from, how is he a groomer or a predator, all the girls are at least 18.
And he's only an awful person if you made those choices, otherwise he's a good person.
And how is D a bimbo, she's pretty intelligent, she was just way too sheltered from everything by her mother.
Encouraging her to fuck whoever wants her is an awful thing to do, because that's just F turning her into a whore, at least there is no money involved though, right?
The only true canon path will be the D only path, no one else, no sharing, just D.
