The logline sets up a complicated situation, but doesn't give anyone an objective goal ?to string up ?a throughline for the plot. ?"Having to grow up faster" does not qualify as an objective goal. ?It's too general and pertains to subjective issues ?rather than objective ones. ?Film is a visual medium; the objective goal has to be something ?a concrete object or event that clearly -- visually ?-- signals to the audience that the character has succeeded (or failed). ?What's the visual for "grow up faster" ?
And it tosses together 4 characters -- who is the lead, the protagonist? ?Or is this supposed to be an ensemble piece of co-equal characters and intertwining plot threads?
