Most Helpful Girl
If she says no it's obviously going to hurt and be a blow to your ego, but it's not the end of the world. There's always a chance that she might not like you back and that you're interpreting her signals incorrectly. However, there's still a chance that she could like you back. Like I said, if she says no then it might sting a bit but there are plenty of other girls out there who won't reject you. You could even stay friends with her afterward if you don't mind the awkwardness. Good luck & I hope it goes well!
