Zhang Shiwu came to the rescue once in an alley when he was a child, and Zhang Shiwu became the only light in Zhao Moying's gloomy childhood.
His grandmother died unjustly, and his mother took him away. The unspoken name became a dusty regret in the young man's mind.
The reunion on the junior high school autumn outing, the helping hand when they were lost, made the two-way secret love grow quietly. Zhang Shiwu gave up a top high school just to be with him; his mother died in a car accident, and the two had nothing, but they became everything to each other.
The shadow of the loss of close friends has not yet dissipated. Su Jianyu's paranoid intervention pushed the bullying into the abyss. In order to protect Zhang Shiwu, Zhao Moying's life stopped forever on the eve of the Beginning of Autumn when the cicadas stopped chirping.
Ten years later, the old Walkman and diary accidentally triggered a time and space vortex. Zhang Shiwu fell back to the past, and was surprised to realize that Zhao Moying was also crossing time and space with his obsession, running in both directions with him.
But the cruel paradox of fate followed one after another - every time he expressed his love, he pushed the other person to death.
They tracked down the real murderer in parallel time and space, tore apart Su Jianyu's hypocritical mask, witnessed the truth of the tragedy of their best friend, and also tasted tolerance and pain in the gap between love and death.
Can the decision to cut off love with my own hands and the fulfillment of the childhood promise break this unsolvable fate? On the eve of the Beginning of Autumn, when the chirping of cicadas gradually subsides, what will be the outcome of this decade-long obsession?
Intention: Confrontation between love and fate
