The provided chapters detail the evolving and increasingly complex relationship between a father and his daughter, Satsuki. Initially, the father cherishes his daughter's childhood declarations of wanting to marry him, viewing them as sweet but temporary expressions of love. However, as Satsuki grows, her desire to marry her father intensifies, moving from childhood pronouncements to analytical planning and eventually, a determined goal to change the law.
On Satsuki's 16th birthday, this ambition culminates in her presenting her father with a marriage registration form, requesting his signature as a birthday present. Her father, a kind but somewhat overwhelmed man, firmly rejects this, emphasizing that marriage between a parent and child is illegal and that he wants her to find happiness with someone else. He is also burdened by the secret that Satsuki is not his biological daughter, a truth he intended to reveal later.
The narrative then shifts to Satsuki's unwavering pursuit of her goal. She dedicates herself to becoming Prime Minister to change the law, demonstrating remarkable academic and athletic prowess, surprising her father with her capabilities. Despite his initial disbelief, he finds himself unable to dismiss her efforts and continues to promise marriage if the law changes, a promise he makes to keep her happy and to avoid crushing her dreams.
Interspersed with these events are flashbacks revealing the father's past. He was bullied as a child and was comforted by his beautiful, mature neighbor, Sasha, who was his first love. Sasha disappeared and returned ten years later, pregnant and seeking his help. She confided that she had married abroad and, tragically, passed away a year later, leaving her daughter, Satsuki, in his care. The father accepted responsibility for Satsuki, driven by a promise to protect Sasha and a growing affection for the child. He consciously tries to separate Satsuki from Sasha in his mind, not wanting to project his past onto his daughter.
As Satsuki turns 17, her affectionate and possessive behavior towards her father continues. She playfully insists on "home dates" and offers him "all of herself" as a gift, which he gently deflects. A pivotal moment occurs when Satsuki directly questions their lack of resemblance, leading her to suspect they are not blood-related. While she muses about how much easier marriage would be if they weren't related, she ultimately accepts her father's denial, though the father is internally conflicted, knowing the truth.
The chapters conclude with the father reflecting on Satsuki's unwavering affection and his own complicated feelings. He cherishes her, but the weight of her intense love and her singular focus on marrying him creates a constant tension. He is aware of the potential for her love to become overwhelming and is torn between his desire to protect her and the need to guide her towards a more conventional future, all while keeping the secret of her true parentage.
