On the 108th day of waiting in the alley, Jiang Xia finally received Lin Xu's decisive words: "Don't wait anymore." After his parents died, Lin Xu moved into Jiang Xia's house, but used alienation to draw a line. He worked to pay off his debts, studied hard late at night, and lived like an island, believing that his broken self was not worthy of Jiang Xia's integrity.
The universities were separated, and Jiang Xia met Shen Youan, a cheerful and cheerful music senior from a wealthy family. His appearance gave Lin Xu an unprecedented sense of crisis, and he realized for the first time that pushing away does not mean protecting, and having low self-esteem does not mean being noble.
When Gu Xiaoxiao appears next to Lin Xu, and when Shen Youan pursues Jiang Xia, the four of them explore the true meaning of love in the maze of youth. This is a belated awakening, a two-way healing of the feelings of childhood sweethearts, which can withstand the wind and rain, but also wait for the rainbow.
