Shutangtang is an ancient thread-bound book pin eye spacing designer whose profession is not found on the Internet. Every day he competes with paper fibers, thread strength, and millimeter-level hole position deviations. Five years later, when she was restoring ancient books at the National Library of China, she reunited with her literary and artistic predecessor Shen Yanqing—the man she had broken up with because of "different worlds and worlds she loved" was now a cultural and creative director who respected digitalization. He complained that the tight spacing of her binding would tear the pages, and she laughed at the fact that his virtual stitches were not breathing. A Ming-dynasty medical book forces the two to work together. The distance between the needle's eyes is fixed in the form of a book, but the distance between them in life is destined to meet and part. When every stitch in ancient books is accurate to the millimeter, is the 1.8-Meter distance between them considered close or alienated?
