Everyone says that Rebecca is very pretty and capable, and that's why she's still single. Her abilities make men feel inferior to her. She enjoys her single life to a tee, but of course, there are situations that make her feel "alone." Her assistant chooses boyfriend over her when work gets busy, so she has to eat alone; her horny landlord makes up excuses to see her; and then there's that overwhelming sense of loneliness. She's not afraid of being alone, but when loneliness strikes, she can't help but think of that person that she mustn't think about anymore.
