The plot thickens. I like where you went with this. It lays the grounds for either a mystery or a romance (or both). Nice!
I love “the source of hallway cat hair” and “The mild night air begged me to walk.” You’ve packed a lot of action into this little piece. And I’m wondering now if the protagonist is simply paranoid and imaginative. Wonderful work.
