Twelve-year-old tied with a red rope, seventeen-year-old silver crane as an alliance, the friendship between Xu Ning and Zhang Heming is the longest-lasting concern in Wutong Lane. He promised to stay together for the rest of his life after returning from the military academy. She waited for her husband to fulfill his promise, but under the heavy blow of fate, she was forced to marry another man to save her father. She cut off the love with the words "find another good match". Misunderstood and misunderstood, she endured an unhappy marriage for half her life, and he survived the storm while watching, but when they reunited, all they had left was the cruel truth of late-stage lung cancer. The misunderstanding was resolved and the affection remained unchanged, but time had exhausted her life, leaving him holding on to the faded red rope and the crane-shaped pendant, chewing on the eternal regret of "meeting so late" in the wind and snow for the rest of his life. This love that started in childhood and ended in life and death has finally become a miss that was teased by fate.
Concept: Young love cannot withstand the tricks of fate. Missing out and regret are the most profound sorrows in love.
