My Brutal Husband Isn't at All What I Imagined

[A frail, pitiful little softie versus a prince who's vicious in public but sweet to her in private, with two sides to him] [An adorable sweet romance with a size difference! Caveat: not a strong female lead; the heroine is a little softie! The hero has no past relationships!] Yao Qing had always thought Yu Chuan was a gift from heaven. As a young man, he wore white as pure as snow, with brows like ink paintings. When he smiled, he was as radiant as the sun, spirited and handsome beyond compare. He comforted her when she was sad, gave her the beautiful lantern she had long wanted but couldn't bring herself to buy at the Lantern Festival, and stood up for her when others bullied her. She thought they would always be happy together. Instead, she heard that he was engaged to Princess Huaichun. Before she could even compose herself, she was told she would be married to Rong Zheng, the bloodthirsty, cruel, and volatile Prince of Yongan. The news came one blow after another, leaving her completely at a loss. Yao Qing had no way to fight back. In a daze, she climbed into the sedan chair bound for the Prince of Yongan's residence. She thought that if she didn't die after marrying into the prince's household, she would surely wish she were dead. But the Prince of Yongan, whom she remembered as ruthless, was nothing like the volatile, terrifying man she had glimpsed from afar in a crowd, nor was he as frightening as the rumors claimed. In public, he was vicious and capricious, but in private, it was as if he became a different person. Around her, he acted as if he had an insatiable need for physical affection, constantly clinging to her for kisses and cuddles. After several tender, intimate encounters, life in the Prince of Yongan's residence turned out to be far more comfortable than her life in her own family home. Note: A sweet, slice-of-life historical romance (maybe).
