Answer:
You need to be yourself. And become friends with her first, get to know her, make sure she feels comfortable around you and gain her trust.
Step-by-step explanation:
As a girl I know this to be true. if you are friends with her first, you have a much greater chance of her liking you back since you guys will already be close. Make sure not to be too pushy or seem too clingy. Girls really appreciate it when you are yourself around them, because if you pretend to be someone you're not, they will find out one way or another. Best of luck to you!
