Fresh milk shop owner Lu Zhiwei has her brand authorization fee raised from 60,000 to 200,000 by trademark owner Lin Man, leaving her no choice but to unlist the brand and create her own "Yixiu Fresh Milk". Lin Man brings her nephew Lin Kai, holding the original trademark, to open a shop across the street, selling OEM milk and relying on low prices and member recharges to grab a large school order. Lu Zhiwei insists on daily hand-milking and bottling at 4:30 AM, refusing to sell overnight milk, and wins back the old neighborhood regulars. Lin Kai is late for the trial order, his milk tastes bland, and milk delivery is interrupted, causing him to lose the bid, and the school selects Yixiu. Lin Man's store experiences a wave of card refunds, and she takes down her sign and closes down. She visits twice, lowering the authorization fee back to 60,000 to beg for peace, but is politely refused both times. Yixiu secures the school's long-term order and bus driver customer base, and her business becomes increasingly stable.
