Naoko has always been close to her father, who has raised her since the passing of her mother three months ago. Though not related by blood, he has treated her like his own child, showering her with love and care. As she grows up, Naoko becomes a working adult, eventually finding a fiancé named Kenji. When she asks her father for his blessing, he agrees, but with a condition: if Kenji ever makes Naoko sad, he won’t hesitate to take matters into his own hands.
Their life together begins with happiness, but over time, the relationship between Naoko and Kenji starts to strain. Their conversations grow fewer, and Kenji begins spending his free time at the pachinko parlor, leaving Naoko to cope with the loneliness. In an attempt to fill the void, Naoko turns to her father, finding comfort in his presence and affection. Their bond deepens, and the once-casual father-daughter relationship becomes something more intimate and passionate.
As their connection grows, Naoko finds herself increasingly drawn to her father, even as her relationship with Kenji continues to decline. The tension between the two men becomes apparent, especially when Kenji returns from work, only to find Naoko and her father in a loving embrace. The emotional struggle between Naoko and Kenji intensifies, but Naoko remains devoted to her father, finding joy and comfort in their shared moments of affection.
Despite the challenges, Naoko’s bond with her father continues to flourish, and their love becomes a source of strength for her. As their lives move forward, Naoko knows that no matter what happens with Kenji, her father will always be there for her — a constant, loving presence in her life.
