Summary
I have come to the realization that most of my fanfic ideas are half baked. I'll write like...a page and never look back on it again. It is 12 AM and I am disappointed in Fighting Yowai content despite his popularity on Instagram (and probably Twitter). Smh my head y'all be simping but no fanfiction?
Will this be a one shot book? Idek
I have no plot

Summary
In 1966, cars were a pretty glorious feature still. Every year, they kept coming out with newer features all across the world. Highways were coming more and more, the fastest mode of transportation. In Japan, it was still better to just take public transportation if you lived in the city, but it never hurt to own a car if you could.
Osomatsu didn't feel very glamorous as he stared at the old brown car before him. They were at a junkyard, and Osomatsu was instructed to stay put and don't talk out of turn. The car was old, beat to hell and back with dents in the passenger side door and the rear end. He also didn't know how to feel with the idea that it was at the junkyard. Weren't those full of trash? It made his childlike brain think the car smelled like trash.
