I agree with Memetchi Dreamer. Two people liking each other is great, but comes naturally.
As a girl, I'll say that I'm into nice, friendly, funny guys that playfully hug you, talk to you and smile at you. You follow those tips and she won't be able to resist you!!
But if she doesn't immediately like you, there is unfortunately nothing you can do. Especially if she's "afraid of love". Could you please specify? Does she not want to date? Is she afraid of rejection/getting hurt? Is she just shy around guys?
