In the fast-paced "Xinghai City", there is an old alley called "Bluestone Alley". The "Yixian Repair Old Shop" at the end of the alley is an "emotional refuge" in the city. The owner, Lu Zhixia, is a craftsman with an introverted personality. He has inherited his grandmother's "memory thread" technique - when repairing old objects with special silk threads, it can awaken the memories hidden in the objects. She guarded the old sewing machine and a house of old things left by her grandmother, but because of her grandmother's sudden death, she wrapped herself in a "cold" protective shell.
26-Year-old Lin Xiaoman had just experienced the double blow of "workplace infighting + love breakup". He accidentally broke into the shop holding an old sweater his mother had knitted before she was alive. The cuffs of this sweater were badly worn and stained with coffee stains that her mother had accidentally dripped while knitting. Lin Xiaoman just wanted to repair it and remember it for a while, but when Lu Zhixia was repairing it with "Memory Thread", he saw a warm scene of his mother sitting under the desk lamp knitting a sweater. Since then, Lin Xiaoman has become a "frequent customer" of old repair shops. From the initial confusion and anxiety, he has gradually become a "little assistant" who can listen to other people's stories and help restore old things.
