When a calculated car crash nearly claims Lu Jinghan's life, Doctor Han's intervention saves him from the brink. The Lu family patriarch sees an opportunity in her heroism, proposing an unconventional solution: his grandson's hand in marriage as repayment for her lifesaving deed. Lu Jinghan steps in to stop the madness, but the seed has been planted. Han Xi, a dedicated physician who views healing as her sacred duty, never expected gratitude to take such an extraordinary form. As time unfolds, Han Xi transforms from savior to the one person Lu Jinghan treasures above all else. His affection runs deep and true, expressed through stolen glances and tender moments. One evening, Lu Jinghan's proposal catches Han Xi off guard: "Let's build a family. Three of us—a perfect whole." Han Xi counters with her own vision: "Two children. A son and a daughter." "One is enough," he insists, his gaze unwavering. "But why just one?" "Because watching you suffer through childbirth tears me apart. One child is all I can bear to see you endure." In that moment, Han Xi feels an overwhelming urge to claim the man who loves her with such fierce devotion.
