Imagine dating Barry and being his enemy

Barry: You need to stop what you are doing otherwise I'll be forced to intervene.
Y/N: You? *chuckles* You, you're going to stop me? *shakes head*
Barry: Don't force me to get involved. *steps forward* *glares* I'm warning you.
Y/N: Who do you think you are, Flash? *rolls eyes* What is your real name? Your identity?
Barry: You're not going to find out.
Y/N: *laughs* Yes I will... Flash, Surely, you've got people to protect. Loved ones. Or just one. Watch out Flash, because I will find them, and I'll destroy them and you.
