Fabs, these are people and you're treating this like some quest in an RPG game. You're going to have much more success if you tailor your approach to who the girls are and how you know them. Unfortunately, given how little you've provided on that front, it's going to be hard for anyone to give you anything but very generic advice.

The bigger possible problem is that you're focusing too much on yourself. You're being a bit of an amateur salesman, trying to sell who you are to them without doing much recon. The best salesmen listen way more than they talk. Why? Because they realize the relationship is the important thing, not the person. Ironically, these are the most well-liked.

So yea, listen. Talk, Vibe. It's called flirting and if you do it right, you'll have plenty of opportunity to ask for a date.
