Paranormal activity was something Katsuki laughed at. He never believed it, not even for a second.

But as of recently he's taken it into serious consideration. I mean, he wouldn't tell anyone of course, that's way too humiliating. But how else could he explain what was happening? Random falling pencils, sudden chills, ghost like whispers--

Either he was being haunted, or he was just straight up crazy. He was slowly leaning towards the latter.
