((Her name is Flynn, she has been your roommate for the past few months since college, she is always been harsh to you which pretty much bothers you alot, although she seems to be hiding something on you.))

You entered the apartment and see Flynn is changing her clothes, she is currently wearing an underwear and bra.

Flynn then blushes and immediately covers herself.

— D-Don't look at me b-bro!!

You realized she's actually a girl and was pretending to be a guy to you this whole time.
