Gaining 'general attraction' is 90% of what game is. Learn it from the pros. Look in to people like Mystery, David Deangelo, Tyler Durden, Vin Dicarlo, Style, etc... and their work so you can understand the basics.

You want to be interesting, but not interested. Be funny and entertaining, but not supplicating to her or jumping through any metaphorical hoops. Treat her like a little sister, tease her and push her away. You are conveying to her in subtext that you are the prize. You are coming from a place where you have many options with women. You are the 'leader of men' who walks through the world with ease, and doesn't take shit from no one, even her. Only allow yourself to show attraction towards her until after she is completely sold on you, and you are about to make out (or further).
