Then you definitely didn't choose all the right answers. You need every single love point to get the scenes, all of them require an exact value instead of a minimum value. You should probably play this game with a mod, either the multi mod on the front page or URM to make sure you're always making the right choices.
Anyway the points you should have at the end of current content from Fiola to Nina going left to right would be 9, 11, 14, 8, 7 and 2. So I'm guessing your Mia's isn't 11 and your Hazel's isn't 8. I said the rest so you can check through to make sure you aren't missing anyone else's.
If your Mia love is at 10 by the end of her birthday party then you'll get her scene if you choose to kiss her. If Hazel's love is at 4 by the end of the scene where you give her a massage you'll get a choice for her third scene. Then after the duel when Mia goes to sleep over at Alesia's you'll get the choice to sleep with Hazel in her bed if you're at 6 love with her.
