Just A Kiss (Dementor x Reader)

The Frost

All throughout the sorting ceremony, i couldn't stop thinking about the dementor from earlier. The way they looked at me, it was different than the way they were watching the other students, different than the way anyone else had ever looked at me.
I dont even know if any new first years were sorted into my house, and i didnt really care. I only cared about whether or not i would see the dementor again.
"...our school is presently playing host to some of the dementors of Azkaban, who are here on Ministry of Magic business." Professor Dumbledore's words catch my attention.
Of course
If anyone knew about the dementors, it would be Dumbledore. I wasn't exactly sure how i would be able to speak to him about the dementors though. I was starting my seventh year at this school and I had never even spoken to the headmaster.
My eyes wandered to the new Defense Against the Dark Arts professor. Professor Lupin may know about the dementors, it was rumored that he was the one who assisted the third year that fainted. I decided that it would be best to speak to him before trying to reach Dumbledore.
We were led by the head boy and girl, to the common room where we could settle our things into our dormitories.
I have two dorm mates: my friend Sarah, and another seventh year who's name i don't remember. I choose the bad near the window.
As i unpack my things, i see a dark shadow out of the corner of my eye. I turn my head, but there is nobody there except my dorm mates. I look up to see that the window had been covered with a white frost. I quickly put my face closer to the window, but see nothing outside except the empty courtyard.
Even though I couldn't see anyone, I knew who was there, because the frost on my window was the same frost that appeared on the window of the train earlier that day. Before I had even seen a dementor, before i truly knew what a dementor was, before the dementor had consumed my thoughts.
I knew that it was a dementor that had caused my dormitory window to frost over, and I had a deep feeling that it was the same dementor that i had made eye contact with just hours earlier.
