Mucha is a hand-presser who irons and adjusts the seam allowances of Song Dynasty Hanfu clothes at "Su Yi Fang" in Hangzhou. He works with millimeter-level fabric looseness every day and believes that "the tenderness of a piece of clothing lies in the allowance." Three years ago, she had a secret relationship with Fu Qingci, the actor who became famous for his costume dramas, but was eventually forced to break up due to status differences. Three years later, Fu Qingci's new drama started filming. Mucha returned to the set as a garment quality inspector and discovered that the cuff allowance of his costume was seriously wrong - it would stretch when he raised his hands. The person in charge of these clothes was none other than Shen Wei, the adjuster of large-sleeved shirts and Fu Qingci's current girlfriend. From cuff welt roll-up to washing shrinkage, from quality inspection confrontation to fabric elasticity attenuation under high temperature, every process conflict is tearing open the old wounds from three years ago. When Mucha opened the dense layer of stitches on the inside of his cuffs, she discovered that for more than a thousand days after the breakup, he had sewn a line of words into his cuffs every day. But the identity gap is always like a seam that is sewn shut - how much margin should be left to be able to embrace it?
