Ling Luo's waiting on the roadside, or a dream. Encountering someone turning around on the street corner, or someone else.
But her long hair has reached her waist, and the young man has promised her a future.
When we were young and young, no one made any promise to anyone. Li Luo once loved Mu Xueqing very much. When he endured Ai Xueqing's loneliness alone, only the egret guarded him. Even if she finally catches up with Xue Qing, her guilt towards Egret becomes more and more greater than the joy of love.
