Her remark could come across rather cold and off-putting. “I live here! do YOU?” I’d probably make up some excuse to leave then, too. :) But it can also be read as if she says it quietly, and he leaves her to find the next prettiest girl.
You did a great job setting up Nalyne’s apprehension over the new school. I wasn’t sure how you wanted me to feel at the end, though.

I thought it was appropriately awkward and uneven, as most such encounters in adolescence go. Frankly, I’m not sure I even knew how I was supposed to feel after any interaction with girls during that sort of time frame (and here I’m assuming they are teens).
