Crush

Just walk up to her and give her a compliment about how she looks, her hair, the clothing she's wearing or just how you'd like to be with her to find out more about her.

If she doesn't respond she just isn't interested in you, but still don't give up.
Good luck

Go hard for it man even if she rejects your advances you will have lost nothing, hope everything works out well for you, just ensure you love her dearly

Don't miss the opportunity pal, you may well regret it for a long while if she is disinterested at least you will know, all the best, she might be a great fuck

Go for it, what do you have lose ... all she could say is no 50/50 chance so just do it.
