Wow man, im impressed by your lack of AA but that being said, as soon as you approached you made your intentions clear, you were there to hit on HB9, the rest of the group probably didn’t want to witness yet another guy try to chat there friend up so they started to fuck with you, make you the centre of their joke/game.

Im still learning myself but heres my opinion on what you could of done:

Possibly shear perseverance would of cracked that shell of her’s or got you totally blown out but she obviously wasn’t impressed.

I would of completely dismissed and ignored her, Entertained her friends, win them over, win her over.
Maybe hit her with a neg or two from time to time but the main priority would be to succeed in earning the rest of the sets approval, disarm the cockblocks.

And if that didn’t work you could of least number closed the powder puff,
