I really don't know what you are missing, it's a bit hard to do it blind without seeing your game, so my 2 guesses are you either didn't progress enough in the weekend visite to the office, so you can make her your girlfriend, or you didn't progress enough in the hearings, meaning the judge, her mother, didn't recognise you as lawyer's love interest, if these don't work, put your save here and I will try to see what you are missing myself
And yeah, I guess in the next weeks I will work on walkthrough on how to unlock the scenes as there are too many people that seem lost, and the game is so big now
