Flirt with her and see what happens

You know, of course, that Emma has a boyfriend, but seeing as how he wasn't by her side right that second, you decided to investigate further.

When she sees you walking up to her, she seems to be at least willing to give you the time of day, smiling at you and inviting you over.

"What's your name?" she asks you, placing her arm around your shoulder, her boobs pressing into your chest as a result of the little sparkly strapless number she had on.

"Name's John," you tell her, "and it's a pleasure to meet you here at a party like this, Emma."

"I don't think I've seen you around here before John, what's your story?" she asks you, but in a way that actually seems genuine to you, which convinces you to tell her the truth and not try to lie to her.

"It's my first time at one of these parties, since I'm new here," you tell her, "and I was honestly hoping to find a friend to hang with tonight."

"Say no more John, I'm your girl," she says to you, in an almost bubbly tone, eyes lighting up when she hears you say it.
