Years later, by a twist of fate, he crosses paths with his former lover, Ami. In a moment driven by a sudden wave of emotion, he tells her a small, innocent lie. However, Ami is now married, living in the quiet happiness of a new life.

Shunsuke, at last, resolves to confront himself once more—but the resolution comes with a bittersweet taste, one that lingers long after the journey ends.
