Sure, here's a backstory for your teenage character:
The year is 1996, and you've been evading authorities for quite some time now. You happen to be one of the teenagers depicted on the missing poster that has been circulating around.
Although funds are limited, you manage to scrape enough money together to board a bus. As you settle into your seat, a youthful man turns to you and inquires, "What's your tale, young one?"
(Could you please provide me with a brief description of your teenage character?)
