“What are you doing here, bro-!?”

For starters, the two of you had only met for the past 2 days. You both have had a rough relationship (you were more persistent than her, maybe that’s why), and thus at a school, you had seen her struggling to defeat some sort of…monster?

You did just jump in from the window and manage to shove her out of the way and gave her an opportunity to strike the demon down, though she was shocked.

“Didn’t I tell ya to stay back, man-!? Why’d ya not listen!?”
