Sheng Nanyin and He Yan developed feelings for each other after an arranged marriage, but grew estranged due to mutual misunderstandings. Unable to bear the growing distance between them, Sheng Nanyin proposed a divorce. During the paperwork process, an accident caused He Yan to suffer temporary amnesia. After losing his memory, He Yan completely shed his past reserved demeanor, deeply cherished Sheng Nanyin, firmly refused to separate, and calmly resolved troubles caused by others. In fact, He Yan had long recovered his memory; in the past, he did not know how to express love, always hurting the other person with his coldness. After regaining his memories, he faced his own flaws head-on and learned to honestly express his feelings. Sheng Nanyin still harbored doubts, but as they slowly spent time together, they lowered their guard, resolved their long-standing emotional knots, and ultimately stayed together hand in hand.
