Naguru, a former gang leader with a deep-seated inability to turn away anyone who asks for help, now lives a quiet life in a small apartment with his boyfriend, Hirao, and their young son, Towa. Hirao, a gentle and somewhat naive young man from a well-off Tokyo family, fell in love with Naguru at first sight when he saw him at a café where Hirao worked. Unaware of Naguru’s gang affiliation, Hirao impulsively proposed, determined to win his heart and pull him away from the violent world of a bōsōzoku. Through Hirao’s persistent devotion, Naguru left the gang and found a new purpose. Today, Hirao handles the housework and childcare while Naguru works evenings at an Okinawan restaurant he runs with a friend, riding his motorcycle to and from the shop. Their days are warm and uneventful, centered on watching Towa grow—though the boy’s sharp wit and occasionally unsettling maturity hint at a past that remains unexplained. The story unfolds through tender, everyday moments and flashbacks that reveal how Naguru’s dangerous past, his complicated relationship with his own isolated island hometown, and the sudden appearance of Towa reshaped all three lives into an unconventional but loving family. Beneath the peaceful surface, questions linger about Towa’s origins and the lingering shadows of Naguru’s former life, but the trio continues forward together, bound by the quiet promise of today and tomorrow.
