Les Suzuki se voient confier temporairement une petite nièce, Mika, dont le père est trop pris par son travail pour la garder avec lui. Malheureusement, la petite fille a été jusqu'alors élevée comme une princesse et elle a du mal à s'adapter à sa nouvelle vie au sein du modeste garage du couple Suzuki. De son côté, Chagawa vit finalement toujours avec Junnosuke et reste autant obnubilé par le prix Akutagawa. Cependant Kawabuchi, le père naturel de Junnosuke, lui pose un ultimatum. Il doit prouver qu'il est capable d'élever décemment Junnosuke si il veut en conserver la garde. Chagawa ne voit d'autre salut que l'obtention du prix Akutagawa derrière lequel il court depuis si longtemps. Encouragé par tous les habitants du quartier, il se met donc à écrire avec passion une nouvelle qui pourrait lui offrir le Graal, et aussi si possible ramener Hiromi près de lui.

Would-be writer Ryunosuke Chagawa is still living across the street from Norifumi Suzuki and his auto repair shop, though now he shares his home with Junnosuke, an orphan he's taken under his wing at the urging of pretty Hiroi, who continues to manage a nearby tavern.

The Tokyo Olympics are about to open, and Rynosuke Chagawa is excited to receive a new TV set to watch the upcoming events. His wife Hiromi is pregnant and he has built a second level on his shop to provide his adopted son Junnosuke with a private space to study for entrance to Tokyo University to set up a career with a major company. He dreams of sparing Junnosuke the struggles that he has faced as a writer. The family continues to rely upon Hiromi's income from her bar. Meanwhile a rival story, The Virus, by a new writer has appeared in the periodical that has been publishing his stories "Boy's Adventure Book" and he fears the new competition. Norifumi Suzuki also receives a new TV, but more of a deluxe model. Mutsuko Hoshino (Roku) is still the principal mechanic in the Suzuki family's auto repair shop, but she dresses up some mornings to go to a nearby street with the hope of a "chance" meeting with Dr...
