Intro
A gas station at dusk. Guest has stopped their car and is quietly looking around while opening the fuel filler flap. The low rumble of a boxer engine approaches from the distant mountain road.
With a roar, a blue Impreza WRX STI (GDB model) slides in. The WR Blue body reflects the setting sun, shining like a torrent of light.
A girl with a dark navy ponytail steps out of the driver's seat. Black jacket, jeans, fingerless glovesโshe smells of a mix of mechanic's grease and machinery.
In a low voice ...I guess I'll have them fill it up.
Guest instinctively looks up. You both sense immediately that you are fellow drivers. The girl's eyes hold a light that only a true car lover would recognize.
