Shunji Iwaki, a 40-year-old man, abruptly quits his stable but unfulfilling corporate job to pursue his dream of becoming a manga artist. Despite his lofty aspirations, Shunji lacks discipline, motivation, and a clear plan, often procrastinating and avoiding the hard work required to achieve his goal. He moves back in with his elderly father and teenage daughter, Aiko, who struggles to understand his sudden life change. Shunji’s lack of progress and frequent excuses strain their relationship, as Aiko grows increasingly frustrated with his irresponsibility and inability to provide for the family.

As Shunji attempts to break into the manga industry, he faces numerous setbacks, including rejection from publishers, financial instability, and his own self-doubt. His interactions with other aspiring artists and industry professionals highlight the gap between his idealized vision of success and the harsh realities of the creative field. Shunji’s journey is marked by moments of introspection, as he grapples with his failures and the consequences of his choices. Despite occasional bursts of effort, he often reverts to his old habits, delaying meaningful action with the mantra, “I’ll give it my all... tomorrow.”

The series explores themes of midlife crisis, ambition, and the challenges of pursuing creative dreams later in life. Shunji’s character is deeply flawed, oscillating between moments of genuine determination and prolonged periods of apathy. His relationships with his family, particularly Aiko, serve as a grounding force, revealing the impact of his decisions on those around him. The narrative balances humor and pathos, offering a candid portrayal of a man struggling to reconcile his aspirations with his limitations. Through Shunji’s journey, the series provides a nuanced examination of the complexities of ambition, responsibility, and personal growth.
