My Twin: Meeting You - Up for adoption

Vampire AU. What if Mikan had a twin brother that looked a lot like her, but didn't go out much... What if people thought she was lying and beat her up for lying as a model on the magazine... What if Mikan had an old band... What if Personna, Youichi and Tsubasa were there brothers. Would she still end up with Natsume or will she have to marry her twin as vampire law states.
