Yūki is a university student filled with uncertainty about his future career, lacking clear direction or a desired profession. This deep-seated confusion causes him anxiety, particularly regarding the common interview question asking him to describe himself in one word, reflecting his broader struggles with self-definition and vocational identity.

His classmate, Michiru, who possesses clear aspirations to become a journalist, provides a narrative contrast. When Michiru undertakes a final assignment involving an interview on a local island, Yūki assists her. During this process, exposure to the island's workers—individuals performing diverse roles within a technologically advanced "smart city" environment—triggers a shift in his perspective.

The island's natural setting, combined with observing how technology integrates seamlessly with daily life and labor, prompts Yūki to reconsider his relationship to work and his self-understanding. While specific backstory details like family history or prior experiences remain unspecified, his development focuses on this movement from confusion towards the beginnings of reflection, catalyzed by collaborative effort and real-world exposure.
