Nineteen-year-old An Wanling held a medical certificate in her hand and saw the end point in advance at the most brilliant age of her life. A mysterious old man deep in the rain alley, a red rope bracelet that couldn't be taken off, a sudden car accident - she actually returned to the classroom four years ago.
In the rain and fog during the Jingzhe season, she met the man who would later become a man with white hair for the first time. At this moment, he is just the unruly young man on campus. Why does the red rope reverse time and space the moment it breaks? What is the story and bond between him and her? Is this just a dream? When the sound of rescue in reality intersects with the chirping of cicadas in the past, she gradually discovers that this seemingly new life is actually a game with fate.
Only he remembers all the rewritten stories and the past between them. In this journey that is both real and illusory, what they are looking for is not only the hope of life, but also the answer to start everything over again.
Intention: Even if we foresee separation, we should still love each other with all our strength. Love can transcend everything, even if I lose you, I will save you.
