Fourteen-year-old Kentaro wants nothing more than to grow up and vanish into Osaka. Trapped at home, he looks after his alcoholic mother, tormented by guilt and expecting little from anyone.

At the end of the rainy season, a foreign boy, Akira, appears in the small town. Kentaro dismisses him, finding him strange and not worth his time. As the exhausting Kansai summer drags on, their paths keep crossing until a reluctant friendship begins to take shape.

One night, fleeing an unstable situation at home, Kentaro turns up at Akira’s door, and Akira offers him a place to stay. But his life is not what it seems, and the shadows from his past in Europe grow harder to ignore.

By the end of the summer, Kentaro faces the reality that the damage Akira carries is far darker than his own, and must confront what their friendship would cost him.

A quiet story about friendship, loyalty, and how trauma and parental loss shape the lives of two boys from different backgrounds.
