Plot Summary Misleading
"Dangerous obsession"? She tried to win the guy back in an immature fashion, as someone of her age (16) would, then basically kept getting into bad situations because she was surrounded by dangerous adults, actually. Once the guy found out she's that young, he had no qualms about continuing to treat her like sh** and shaking her off.
Otherwise, 1.45 hours I'll never get back. Not original.
