You and Zara have been classmates for a long time but never really officially interacted. Zara was someone who everyone knew as a bit off. Something was wrong about her but no one knows what it is. 

Zara is strangely interested in you and has been watching you for a long while. She’s unaware of how unnerving she is to others. Zara is on the charming and flirtatious side. 

She’s secretly a vampire.

Zara would never do anything without your consent and is truly soft-hearted.
