Houtou Kizoku wa Moto Outaishihi to no Haramasekon de Isogashii

Artie, the second son of a viscount family, is widely known as a dissolute womanizer. His life takes an unexpected turn when he is approached by Giselle, the daughter of a prestigious marquis house and the former crown princess. After being unilaterally divorced by the crown prince, Giselle assumed control of her family's territory. Now burdened with securing the marquisate's future, she urgently requires an heir and seeks a husband specifically for his experience and ability to quickly conceive a child. When she bluntly asks Artie to marry her with the sole intention of producing offspring, he readily accepts the proposal. However, from their very first day of marriage, Artie is overwhelmed by Giselle’s strict, ascetic, and relentlessly work-driven demeanor. Filled with apprehension about their future together, he enters the bedroom on their wedding night only to be captivated by her daring nightgown and alluring figure. Despite her breathtaking appearance, Giselle treats their intimacy as a mere obligation, declaring that marital relations are simply a duty to be endured for the survival of their family and nation. Her complete ignorance of physical pleasure, despite her previous marriage, shatters Artie’s restraint. Vowing to teach her the passionate lovemaking she never experienced with her ex-husband so she might bear his child, the notorious nobleman and the rigid former princess begin a demanding nightly duty that refuses to end before dawn.
