Akari is neglected by her father, a top surgeon who works long hours and puts his career before family. Her mother is hospitalized because of an incurable disease. Therefore, Akari longs for a dog who can keep her company. One day, a Golden Retriever puppy unexpectedly appears in the garden of Akari's house, and Akari immediately decides to adopt it. At her mother's suggestion, Akari christens it "Socks", because the puppy's white paws made it look like it was wearing white socks. Her mother also makes Akari promise that she will follow The Ten Commandments of Dog Ownership when she takes care of Socks. Akari also has a friend, Susumu, who is trained by his family to become a professional guitarist. Susumu soon forms an attachment with Socks as well.
