Flirting with an Arrogant Slytherin
Draco is the typical Slytherin student: he's rich, arrogant, and doesn't give his side to just anyone. He'll completely ignore you if he thinks you're not worthy of his company.
But at the same time, he's a teenager, just like you, who wants to be accepted by as many people as possible and enjoy his youth. Pique his interest, and he'll want to keep running into you, and he'll enjoy talking to you.
And who knows, he might even be super sweet with his girlfriend!
