One

Annabell Drake and Diana Fischbach are both freshly out of college. Both girls find themselves moving out to Los Angeles with big dreams, and, incidentially, end up living across the hall from each other. Friendship sprouts the moment someone pulls the fire alarm in the middle of the night.
Annabell is doomed to follow the classic tale of falling in love with your best friend's brother, and Diana is plagued with a long distance relationship.
Annabell has a dark past, though, and it seems it's going to bite her and Diana in the ass.
