Kouhei Aizawa, a 20-year-old photographer focused on nude artistry, balances restless ambitions of adopting a drifting lifestyle in the U.S., inspired by his American grandfather. His carefree, impulsive exterior conceals a habit of evading personal struggles through escapism. Moving to Karuizawa reignites ties with childhood friend Kaoru Matsunuma and introduces Noriko Kuonji, an ex-biker gang leader whose influence nudges him toward maturity.

Flirtatious charm and a confident guise veil his insecurities and craving for approval, yet fleeting introspection surfaces as he contemplates his rootless existence and unfulfilled dreams. Relationships with these women unravel his reluctance to face responsibility, prodding him to grapple with fears of failure and commitment.

Unmarked by scars, glasses, or facial hair, Kouhei navigates life in a Jeep, symbolizing his love for freedom and movement. The story’s visual language—shifting between standard animation, chibi exaggerations, and rough sketches—echoes his volatile emotions, underscoring both humor and self-reflection.

Canonical sources omit details about his family, education, or future beyond the narrative. His journey ends with hesitant strides toward self-realization, leaving long-term growth ambiguously poised between change and continuity.
