In the cold fog of late autumn in northern Guangdong, the rolling shutters of Xinyi Hardware Store rose on time. Ding Yi clutched the old mechanical watch left by his father. The word "Xinyi" on the back of the dial made his skin feel hot. Ten years ago, he was a little beggar huddled in front of the store. Now he is a young boss who wants to protect his family business in the sea of desire. When the Xiong family and his son smashed up stores and robbed them, he protected the signboard with his fists; his rivals started a price war, but he relied on word-of-mouth to win back the neighbors; the homeless boy he picked up turned out to be a fellow villager, and a past incident brought out the old grudges between his parents. A wrench, a bench, and a young heart that refuses to admit defeat. What he protects is not just a store, but his father's last wish, the weight of the word "faithfulness", and more importantly, his own piece of sea in a market full of desires. "My dad said that in business you must be honest, but if someone offends me, I will offend them."
