Is this romantic or platonic attraction? (I'm guessing platonic)

So I have this girl in my class, she is alternative like me and I think she's sooooo cool T-T

I get pretty nervous around her and it makes me super happy when she talks to me, even if she only says hi

I don't want a romantic relationship at all (might be cuz I'm asexual and mostly aromantic), but I love her personality and style, I wish I had the courage to talk to her more. I probably think about her more than she thinks of me. I've identified as straight- asexual- fictoromantic for a while now
