Hey, so there are a bunch of instances early on right after your first encounter that specifically refer to the imposing stranger as a man, even though I chose female pronouns.
"To them, the man's send-off was genial. Familiar, even."
"You don't know if you want to turn around and confront the man so nonchalantly intimidating, crawl into a hole, puke, or get home and forget about the night entirely."
"Oh, god, what if it's the man from last night? You glance at the takeout bag."
"Not that there is anyone in this city who would recognize your name or your face except for maybe your landlord. And the man who rescued you."
I only just started so I don't know how many there are, but maybe a CTRL-F through the script for "man" would be prudent, as I get the impression you have a rather firm picture of the character in your mind when writing.
EDIT: Well, that was neat! Definitely keeping my eye on this one.
