After her divorce, Lin Lan starts over with an old sewing machine. Starting by altering clothes for acquaintances, she clearly separates every piece of income and expense, while systematically sorting out the belongings and boundaries left behind from her past marriage. Zhao Yue values her steady way of doing things and accompanies her to start trial sales with three sample garments. Together, they continuously modify paper patterns based on customers' try-ons, handle returns and alterations, control inventory, and build up a reputation and revolving funds. As the ex-husband, Zhou Cheng also shifts from initial discomfort to slowly learning to interact according to agreements, carry and pay for labor wages, settle old accounts on schedule, and return old items to their respective owners. Instead of rushing to expand the business, Lin Lan builds a stable small shop out of half a counter through repeated small trials and long-term record-keeping.
