of course I have comprehension problems, the guy I'm talking keeps failing to give accurate/pertinent information about his problem, first you got rejected... then it was no interaction... now we are back to rejection.
This game has a lot of similar interactions if you fail to be specific, you can't expect accurate answers.
The quest hint for Vanessa pops up long before you can interact with her (before the Photoshoot), that event only becomes available after the photoshoot (No Interaction). I never had any issues getting a date with Vanessa after the photoshoot, if you are, then I'm guessing there are other parts of the story you need to do first or stats you have to increase. If/When you get your date with her you will be given two options, 1. Be a Man and take charge or 2. Be a Boy and let her take charge... if you don't take charge you won't be able to date her again until she is ready... Don't call her, she'll call you (aka she will "REJECT" you), and make you wait for her to phone you (like Camilla), I'm not sure she ever does in this update, I never explored it very far.
Some people have experienced a bug where she doesn't appear at the date, but that doesn't seem to be your issue.
If words fail you maybe try screenshots, The screen where she "rejects" you, your quest hints and stats might be useful. (either way I think I'm done)
