In the slow-paced Yunqi City, 28-year-old Su Wan runs an old item restoration shop called "Time Sewing Shop". She is a complete "nostalgic" and can restore yellowed old photos as clear as ever, but she is always troubled by her "obsessive-compulsive disorder" - the stitching of repairing old books must be aligned with the page numbers, and even the gears of old clocks must be polished. In the newly opened "Moli Bookstore" next door, the 30-year-old Lu Shiyan is a casual shopkeeper who can accurately recommend books that fit readers' moods. However, he is often ridiculed by customers for his "Buddhist management" and always arranges the bookshelves crookedly. In an accident, Su Wan was in urgent need of special paper to repair an out-of-print old book commissioned by a customer. She accidentally rushed into the "Moli Book Club" and knocked over the stack of books that Lu Shiyan had just sorted. Even the repair kit in her hand was scattered on the floor. One uses stitches to extend time, and the other uses the fragrance of ink to heal the soul. The two people with huge contrasting personalities gradually get closer in the ridiculous intersections. Su Wan helped Lu Shiyan repair damaged ancient books, and Lu Shiyan recommended precious books related to old things to Su Wan. When the delicate stitches meet the rich fragrance of ink, and when the true souls touch the casual heartbeat, they not only heal each other's shortcomings, but also find their own "romance in time" in each other.
