Xu Qinghe's fifth birthday present was his younger sister, Xu Haiyan.
She was always saying strange things, like, “Brother, I saw you crying in the arms of a big boy.”
He thought it was just a child's joke.
Later, his parents' marriage fell apart, and Xu Haiyan's health began to fail. When he was fourteen, his sister left him for good.
At eighteen, he went to visit her grave.
That day, he met a mysterious man named Jiang Zeng.
From then on, everything connected to “Xu Haiyan” began to disappear.
He had wanted to give up investigating, but the truth only grew more puzzling...
His first love, Zhong Ziyi, had a fiancée.
And the person who spoke up for him was none other than her: Dan Jifu.
There was also a girl who always appeared whenever he was feeling down, Bai Yeli. She comforted him at just the right moments, but never said who she was.
As he drew closer to the truth, the first snow fell in Lancheng, and the words spoken thirty years ago finally came to light.
If there is another life, I wish to promise you...
Peace and prosperity.
