On the day when the imperial examination results were released, Wen Zhiyu decided to break off his engagement to Jiang Jingheng because the boundary between him and his nanny's daughter Liu Qingyuan was blurred, which made him feel bitter. The former baby kiss and more than ten years of obsession could not withstand the disappointment and betrayal again and again. Half a month later, she followed her brother to the frontier and said goodbye to the entanglements of right and wrong in the capital. At the border, she let go of the past and met the high-spirited Yan Linzhou, and her brother also found a good relationship. However, Jiang Jingheng's regret and Liu Qingyuan's calculation were all gone, and Wen Zhiyu finally came to the grassland and ushered in a new life with a warm heart.
