At eighteen, Wen Ning received two letters: one offering her a place at a prestigious high school, the other diagnosing her with cancer.
She chose to hide her illness and step onto campus. In the final days of her life, she met Fu Xijing. He stayed by her side through the changing seasons, and she left him seventy letters before his college entrance exams. By the time he got into university, she had been left behind in yesterday forever.
Many years later, someone asked him if he had a girlfriend. He said, "Yes. I love her very much."
Love lasts a long time, long enough to cross the boundary between life and death. With seventy letters, Wen Ning accompanied Fu Xijing through his youth.
And Fu Xijing spent his whole life answering those seventy letters.
