During the war, nurse Su Yao and officer Chen Feng met at a field hospital. They protected each other amid a hail of bullets and promised to stay together after the war. On the eve of victory, Chen Feng went missing. After waiting in vain, Su Yao returned to her hometown and opened a clinic. At a commemorative exhibition in their later years, they reunited. Chen Feng, now missing an arm, and Su Yao embraced through tears, rekindling their old love. Fate played a strange trick on them: they transmigrated to ancient times, continued their romance, and married. But Su Yao vanished on the night she gave birth, leaving Chen Feng to search for her desperately. Su Yao woke from a dream in tears, turned it into a novel that attracted widespread attention, and saw it adapted into a TV series. In real life, they loved each other just as deeply as before. Even through hardship and temporary separations, Chen Feng always stood by her. Su Yao was the one and only love of his life.
