Liu Qingyi and Su Xuanjun met on a blind date. He said he fell for her at first sight. He told her he loved the way she had dressed for their date: a pure white long dress, her hair half loose, like a fairy descended to earth. Because Su Xuanjun said he liked that look, Liu Qingyi gave up the bright, striking style she had always preferred.
Liu Qingyi and Su Xuanjun loved each other and stayed together for a lifetime. They felt they had met too late. Liu Qingyi said that if she could go back to her student days, she would seek Su Xuanjun out at once. After Liu Qingyi died at the age of eighty, she opened her eyes and truly found herself back in her student days, where she and Su Xuanjun came to know and miss each other. Then Liu Ruyan appeared, making Liu Qingyi wonder if she was just a substitute.
