should i (girl) ask a bi girl to hoco if she already likes this guy

I(18F bi)’ve thought she (17F bi) was cute for a gear or two and this year she’s in on of my classes. I don’t know if I should ask her to the homecoming dance that’s next saturday. We’re both introverts and our total conversation ever made with each other don’t exceed 30 min. We’ve hung out once last week with mutual friends (my friend asked us to hang out because she knew I liked my crush!) but it was a little awkward. We had conversations by ourselves and joked a bit, but didn’t instantly click or anything. To “would you get a girlfriend” she answered “idk, I think I look too straight and no girl will like me” or something like that. She’s also mentioned that she wants a boyfriend. We both like and want to major in art. She follows my art account and I think my art and outfits that she’s seen are pretty cool, and she’s complimented me on those things before so my chances aren’t completely 0.

NOW the important part is i know she has a crush on a guy but I don’t know how deep it is!!Based on something she said this monday (“I’ll ask him his fav color next time”) they’re probably not that close. Should I take my chance and ask her today after art class?
