At twenty-nine, Hiroto Ikuta lives a life that confuses almost everyone around him. Working a part-time job at a local fishing pond in the Asagaya neighborhood of Tokyo, he has no full-time career, no girlfriend, and no concrete plans for the future, yet he possesses a deep and unshakable sense of contentment. His days are defined not by ambition but by small pleasures and genuine human connection, most notably his daily visits with an eighty-three-year-old retired school lunch cook named Hanae Wada. Despite her grumpy exterior, Hanae has become Hiroto’s closest friend, and their unlikely bond brings a quiet warmth to both their lives.

This gentle rhythm is broken when Hanae suddenly dies of a heart attack. In a surprising final gesture, the childless woman leaves her old-fashioned single-story house, a hiraya, to Hiroto. Shortly after inheriting the property, his eighteen-year-old cousin, Natsumi Kobayashi, moves in with him. She has left her hometown to attend an art university in Tokyo, harboring dreams of becoming a professional manga artist. Where Hiroto is meandering and at peace, Natsumi is anxious, socially awkward, and driven by a desperate need to prove herself. As they settle into their new shared life under one roof, the story explores the quiet friction between his decision to let life happen and her struggle to force it forward.

The series unfolds through the daily lives of Hiroto, Natsumi, and the people orbiting their modest home. Hiroto’s best friend from high school, Hideki Noguchi, represents the conventional path of success. He has a demanding corporate job, a pregnant wife, and the trappings of adulthood, yet he is secretly crumbling under the pressure of his manager and the fear of failing his family, to the point of contemplating suicide. In contrast, Hiroto’s lack of status provides a rare safe harbor for Hideki, a living reminder that a person’s value is not tied to their productivity.

Another key figure is Yomogi Tachibana, a high-earning real estate agent who initially has an embarrassing encounter with Hiroto. Despite her financial success, she lives a lonely existence in a sterile high-rise apartment, lying to clients to close deals and struggling to find genuine happiness. Her growing connection with the carefree Hiroto forces her to confront the emptiness of her workaholic lifestyle. Meanwhile, at art school, Natsumi slowly befriends a shy classmate named Akari, and together they navigate the competitive, often discouraging world of creative ambition, facing harsh deadlines and the constant fear of rejection from manga editors.

As the cousins continue living in the late Hanae’s home, the narrative arcs focus on the contrasts between generations and lifestyles. Hiroto, who once gave up on his dream of becoming an actor after growing tired of the competitive audition circuit, serves as a mirror for Natsumi. While he models a life where resting and giving up are not failures but choices, she represents the burning drive he has lost. Through festivals, shared meals, household repairs, and quiet evenings, the story does not seek to resolve their differences but to find beauty in them. It acknowledges the darkness of burnout and social pressure while ultimately celebrating the healing power of slowing down, finding a place to call home, and simply being allowed to rest. A live-action television adaptation of the manga was produced, premiering on November 3, 2025, on NHK, with Amane Okayama portraying the easygoing Hiroto, Nana Mori as his cousin Natsumi, and Riho Yoshioka as the real estate agent Yomogi.
