We Parted on Our Wedding Night! My Pregnant Nausea Made the Prince Kneel and Coax Me

On their wedding night, the prince coldly tells his new bride that he already has someone he loves. The princess bursts out laughing. The emperor is infertile, and the entire royal family is counting on the prince to have a son. He warns his wife, “Behave yourself. Don't think you'll ever win my heart.” She thinks to herself: Your empress dowager mother and emperor brother are both begging me. If you don't know what's good for you, then I'm going to... Later, the prince loses his heart and falls in love, abandoning all proper business to trail after his princess all day. Holding their adorable child, she sneers, “Try acting a little more aloof. Neither I nor the baby can stand you acting like such a lovesick puppy.” (Goofy, strong heroine + mutually faithful couple + healing + everyone dotes on her + groveling-to-win-her-back romance)
