I think for me, my favourites are Lucy and Maddie for love/sex and Fiona for a balanced relationship: it really is like a couple of besties or close siblings.
NO, I never realised there were that many. I have just finished chapter 12. Thing is, I do not want to go too far without the Lucy route. I have already gone further than I expected to, but I guess I can always skip the dialogue. I think it is just a shame they made a Lucy route in the first place. To me, it would of been better to of just included her like all the others.
