The manga follows Shigeyuki Fukumitsu, a mangaka known for his deeply autobiographical "private manga," as he reflects on his life more than two decades after completing his earlier work Boku no Shokibo na Shippai. Now married and raising children, Fukumitsu continues to confront a long trail of personal and professional failures that have persisted across nearly twenty-five years. The narrative examines how mistakes, anxieties, and regrets evolve over time, shifting in form as he navigates the ups and downs of domestic life, parenting, and the creative struggles of a career that has never quite stabilized. The central figure is Fukumitsu himself, presented as a candid, often self-deprecating observer of his own shortcomings. His wife appears as a steady, supportive presence who helps anchor him amid his ongoing uncertainties. Set in contemporary Japan, the story unfolds as a series of slice-of-life vignettes that blend present-day incidents with flashbacks to earlier missteps, emphasizing the cyclical nature of failure and the small, unglamorous efforts to move forward. Notable arcs explore the contrast between youthful optimism and middle-aged realism, the humor and melancholy found in everyday routines, and the quiet perseverance required to keep producing honest art. Rather than offering resolution, the manga suggests that failure is not a phase to escape but a constant companion whose shape changes even as its presence remains.
