On the day Ruan Niannian recovered from her deafness, she walked in on her fiancé Jiang Shenghuai being intimate with Jiang Shiyu, the very person who caused her deafness, realizing all her years of sincere devotion had been utterly wasted. At her moment of utter despair, yielding to her mother's desperate pleas, she agreed to take the place of her runaway sister Ruan Jiaojiao and marry the notoriously ruthless Second Young Master Huo, Huo Lin, entering into a one-year contractual marriage. After the wedding, Huo Lin, having long seen through her substitute identity, secretly protected her safety all along, helped her squash workplace rumors, fought off Jiang Shenghuai's harassment, and shielded her through the internal feuds of the Huo family. As they spent time together, genuine feelings gradually blossomed between them, and Ruan Niannian slowly walked out of her childhood trauma while healing her intimacy anxiety. In the end, their affection grew deep and they held a grand wedding.
