"I don't need to fulfill my wifely duties"...or so she thought. But wait, it seems she's fallen in love with him!? The peaceful(?) newlywed life of a slightly off-kilter, authentic young lady and a strict Marquis!
I really don't want to. But I can't imagine a future without you! Anneliese has married Arnaud, who is rumored to be a cold-hearted, strict Marquis. At first, Anneliese hated marriage and even ran away from home, but when he told her, "All I want from you is to be the mother of my son, Michael. That's all," she accepted the proposal. Still, since they're living in the same house, she thought they should get along, and decided to make Arnaud's favorite salad... But... Arnaud, who had previously been indifferent, is now troubled by his slightly(?) off-kilter wife's behavior...!?
