Lin Yu takes over a closed street corner coffee shop. Instead of rushing into a major renovation or filling up the menu, he starts over from three basic drinks. Faced with old equipment, a limited budget, and tedious operating procedures, he diligently learns grinding, extraction, milk foaming, and cleaning, keeping clear records of every cup served, waste, and restocking. With the help of friends, his master, and property management, he constantly discovers problems and adjusts procedures, step by step stabilizing the small shop. On the tenth day, the equipment and operations smoothly pass inspection, and the lights at the street corner light up once again.
