I look at this adorable pic, and an entire 20-year-old radio commercial for AM/PM convenience stores automatically plays in my head.
"Summertime. High noon. On AM/PM time, this is known as: the flip-flop. Faced with long, carefree afternoons, otherwise decisive people find themselves at a loss to pick the day's activities--and the choices can be staggering. A nap at the beach. A nap in a hammock. A nap in the back seat of your hoopty. Feeling overwhelmed, many people simply do nothing. This, too leads to a nap."
I leave it as an exercise for the reader what Sakuya's hoopty would be like, but I assume Marisa's would be a 1964 Ford Falcon convertible. Black, of course. With yellow seats.
