I talk to her at school, whether she is in a classroom or in the hall, she just gives me a hug and invites to the roof party. Before that she invited me to prank those rappers, earlier she didn't want to talk because of a new dress-code and so on. Every time she reminds what I should do to continue her quest, there were no situations when I should just wait for a couple of days after making some progress like with other characters, I guess this is when artpad question should be available, but it just doesnt happen
