She's Vintage Vixen and he is Chasen Cupid. They have odd names, odd parents, and hate pretty much everything and everyone, but especially each other.
When Cupid gets mad when Vixen ruins his art project so hers can win, he fires a love arrow at her.
Only, she doesn't look at the next guy walking through the door, she looks at him and the madness ensues from there as they attempt to break an unbreakable spell.
