After Shen Zhifu was framed by villains, his entire household was slaughtered. His daughter, Shen Zhiyi, had gone to a temple to pray for blessings and escaped the massacre. She drifted to the capital, where she was saved by Su Mingwei, the daughter of a high-ranking official. To repay her kindness, Shen Zhiyi married the Crown Prince, Xiao Jingyan, in Su Mingwei’s place, since Su Mingwei’s heart belonged to a general stationed at the frontier. In truth, Shen Zhiyi wanted to investigate the massacre of her family. Coldly received on her wedding night, she mistook Xiao Jingyan for her father’s killer, unaware that he had fallen for her at their first meeting at the temple where people prayed for blessings. As the Empress plotted against her, her identity was exposed, and Su Muci pursued her, the pair weathered misunderstanding and hardship together. At last, they joined forces to break through the schemes and uncover the truth, moving beyond the tangled affair of stand-ins to a love that flourished in a prosperous age.
