How do I ask my crush to homecoming when its in 1 day?

So I have a crush on this cute guy. It hasn't been much since I started initiating conversations with him. The next time I see him will be on Friday and the next day (Saturday) will be homecoming. Should I just be straight forward and ask if he's even going first then casually be like "will you go with me to hoco?"
How can I make it a bit less awkward?
