Affection is a semi-hidden stat in Adventure High. It shows what a person thinks of the Protagonist.
From highest to lowest, it goes:
3 hearts (in love). At present time, no one starts with this.
1 heart (crush). Valerie and Erin are the only ones at present who starts with this.
Angry waves (don't care). Ms. Rack, Jane, Molly and Eric all start at this level.
Middle finger (hate). Everyone else starts with this.
