The 65-year-old anonymous writer Wang Wenxuan and the 22-year-old drama graduate student Xia Yuhua met on the Beijing subway over a novel "You're So Good". He is the restrained mourner in the book, and she is the reader who weeps over it. A dialogue spanning ages, regions and life experiences begins: from email exchanges and discreet conversations in cafes, to reunions in Paris and fierce declarations in New York. She translated his words onto the stage, and he responded to her presence in the novel. When illness and time are approaching, they define each other as "parallel lines are always with each other": they do not intersect on the secular track, but in the curved space of words, with the deepest understanding and the most restrained approach, they complete a long exploration of loneliness, memory and love. This is not a love story, but a profound experiment in how to create an eternal connection without possession.
