A bond in the rain spanning twenty years, three destinies torn and sewn together by memory. In 2005, the rebellious boy Lin Xianyu knocked down the orphan girl Su Nianan in the rain. The girl protected him with lies, but then disappeared from his world. The boy grew up alone with regret and a pair of new shoes, until ten years later he reunited with Nian An on a bicycle in the rain, and frantically chased back his lost lover. However, before the sweetness is enough, Nian An mysteriously disappears again, leaving Xian Yu to transform into a top star Lin Zexuan in despair.
Ten years later, when Lin Zexuan published his autobiography in search of love, the appearance of ghostwriter Xu Jingya turned everything upside down - she was the amnesiac Nian An, who is now the support of her paralyzed husband and young son. As memory fragments come in like a flood, Nian'an runs wildly on the rainy night and shouts out his true identity, but falls into a deeper moral dilemma: Should he return to Xianyu, who has been clinging to him for twenty years, or should he continue to play "Xu Jingya" and repay his guilt for his savior?
When the paranoid group heir secretly stirs up the storm, and when the truth tears away all disguises, the three souls teased by fate will finally face the nature of love in the rain of their first encounter - is it the tenderness of fulfillment, or the obsession of possession?
