Afreenity is considered as Afreen's aura, her vibe, her energy, her mental and physical health, her emotions, her feelings, her presence, her company. Basically it's something you can feel but can't see, and if anyone of these are low then it's considered her having low Afreenity and if it's high then she's having high Afreenity, if she has low then maybe she's having a bad day or talks less than before, and high Afreenity is being active more than usual
