Akari Saito Akari Saito grows up feeling the weight of a father who is a dedicated surgeon, constantly absorbed in his work, while his wife—Akari’s mother, Fumiko Saito [/actor/reiko-takashima]—battles an incurable illness and is hospitalized. In the quiet of their garden, a Golden Retriever puppy named Socks arrives and becomes a beacon of companionship for the lonely girl. At her mother’s urging, Akari dedicates herself to the care of this new friend, and the family’s homebound life takes on new meaning as Socks brings warmth into a house stretched thin by illness and absence. Akari’s friend, talent-seeking guitarist Susumu Hoshi [/actor/ryo-kase], also grows attached to Socks, sharing moments of music and comfort with the dog.
A few months pass, and tragedy strikes: Akari’s mother dies, revealing that Socks was a gift from her, a living memory of the love that once filled their home. The family relocates to Sapporo after her father earns a lecturer post, but the dormitory bans pets, forcing Akari to entrust Socks to Susumu. This separation tests everyone, yet Socks remains a thread that ties Akari to her past. As life unfolds, Susumu earns a place at a prestigious Parisian music school. On the day of his departure, Akari’s father—who was meant to be off on leave—receives a hospital call for an “emergency” operation. The reveal later shows it as a minor procedure, and the stress of the moment pushes him to resign from his position, a choice born of guilt over disappointing his daughter. The family eventually moves back to Hakodate, and Socks returns to their care, while Akari’s father quietly establishes a home clinic that quickly gains popularity among locals.
Ten years glide by, and Akari becomes a university student training to be a veterinarian. She spotlights Susumu’s return to the city with a poster announcing his upcoming performance, and the two share a tearful reunion that blossoms into a romance. In this phase of life, Akari begins to feel Socks is a constraint on her commitments, a tension that mirrors the sacrifices demanded by her growing career and ambitions. After graduation, Akari becomes a zookeeper at Asahiyama Zoo, her life increasingly busy and her visits home becoming rarer, yet Socks’ quiet presence lingers in the memories of both Akari and Susumu. It’s Socks who helps Susumu regain his confidence to play the guitar again after a career-altering accident, a turning point that deepens their bond.
As Socks grows old, Akari’s visits become even less frequent, until a day when she rushes back to the home she once left behind and finds Socks fading. Her father’s news confirms the dog’s waning energy, and Akari hurries to Socks just as the last light drains from the old friend. In a moment of quiet reflection, she re-reads the Ten Commandments of Dog Ownership, recalling the promise she made a decade earlier. After Socks passes away, Akari and her father uncover long-lost photographs and a letter from her mother. The letter reveals that Socks was meant to stand in for her mother, even as she adds that Socks would not live as long as Akari. It also honors the sacrifices of the father, who chose family over his career. In time, Akari and Susumu’s paths converge again in marriage, a testament to a life built on memory, devotion, and enduring friendship.
