Gui Xiao and Lu Yanchen were in their first love. After graduating from college, Lu traveled to a remote city to become a special policeman officer. At the same time, Gui's family encountered accidents, and their love ended in nothing. Ten years later, Gui and Lu reunited, finding it impossible to suppress their longing for each other and getting closer again. However, the news that his parents arranged a marriage engagement for Lu made Gui uneasy. Lu decisively made a choice, and Gui understood that he had only herself in his heart from beginning to end. The two continued their relationship and registered for marriage. After marriage, Lu was injured in a mission and fell into a coma. The pregnant Gui rushed to Lu's side and gave birth to her daughter in a border city where Lu had been guarding for ten years. A family of three reunited peacefully and lived a happy life.
