I started with the modified 0.8.5 qsp: all stats 100, all love 3000, chose ONE MILLION dollars.
Foxy: check in on her at her room before 7. Keep looking! After that interact in the kitchen before 17 pm until interaction returns to normal. Choose the right answer to her question, I think it's Continue in this case (save; the wrong answer will give a pretty obvious warning) Give her lingerie (it's supposed to be hinted at in the text, but I didn't see it). Now you interact with Foxy in the dining room before 20 pm, same warning about saving as above. After dinner returns to normal you run into her in the house and give her books. Visit her daily to give new books.
If you find out what to do next: I'd like to know that too.
Gina: not a clue yet. She's supposed to have a boy visit after which paths open up (according to one of the posts above), but I can't trigger it.
