X-Files (MSR or gen)
Fox Mulder was not good at personal space.
Her first thought was that he’d been in the basement for too long, had forgotten how to interact with real people. Part of her found it charming, and another part of her thought maybe it was just sexism. She sometimes wondered if he did it just to be off-putting.
It took her an embarrassing and flustered several months to realise that he simply… liked her.
He liked her, personally, and for the life of her she couldn’t figure out why. But what baffled her the most is that she liked him, too.
