Just A Kiss (Dementor x Reader)

DADA

The next day was a blur. I couldn't focus on my classes, i couldn't stop thinking about the dementor. Do they have a name? How long would they be at Hogwarts? I had so many questions, but nobody seemed to have the answers.

Another student asks yet another question about Voldemort and a baby, before Lupin finally calls on me.
"What do you know about dementors?" I ask.
"Ah, Ive been waiting for someone to ask about the dementors." Lupin says,
