The campus romance between the heroine Lin Yejuan and the hero Xu Baishan made the most dreamy promises in the beautiful years, but in the end Xu Baishan gave Lin Yejuan an absurdity, and no matter how much she devoted to love, it would not help. Coupled with the love in the eyes of other classmates, Lin Yejuan slowly let go of everything.
