Futari Bus

Shunpei lives in a rural town of barely 3,000 people. Every day, he rides the same bus as his classmate An Takayagawa, the only one who went off to a private middle school. The two haven’t really talked since elementary school until one day, something gives them a reason to. A soft, sky-blue not-quite-love comedy, born on a bus for two.
