I always thought of this as the first in the trilogy where the boy is just being dumped by Jennifer, pleading that he'll love her endlessly. When she isn't convinced, his words take on a new meaning where he can't and won't be satisfied until she's dead and is only "his". The next being Midnight Show where he murders her, and the final song in the trilogy being Jenny was a Friend of Mine where either Jenny's actual murderer is being questioned or her new boyfriend who is a suspect.
