Ego, Jealousy, and insecurity are traits I'm sensing from these characters. The slim girl wouldn't let go of her ego as a lady and approach the guy of her dreams. Gloria is extra-dramatic and insecure, and since she doesn't want to date David, she doesn't want other ladies to do so. David, on the other hand, is tired of the ghost chase and wants something real this time round, but his crush is crushing his chances. I wonder how things would turn out.
