EveStanford
Faith Roe. Not noticed by many, difficult to find and cold. She's shut everybody out since she was young, she's never had friends or a boyfriend and her only connection to anyone is her to her alcoholic mother, who she's sure doesn't love her anyway.
Fred Weasley. Noticed by everyone, easy recognised by his hair (but often mistaken for his twin brother), loud and friendly. He's always been a prankster, him and his twin brother George cause absolute havoc all over Hogwarts. He comes from a ginormous family and is absolutely surrounded by friends, all of which completely love him.
When George gives Fred the challenge of making Faith love him, she is immediately told by Hermione. She tells Fred to stay away, that he's lost already and she doesn't let people in. But little did Faith know, Fred didn't like to be told what to do and she'd sparked an incredible interest in him.
She was never getting rid of him now.
