Lin Xiaonuan, owner of the Lin Kee Rice Noodle Shop in Linjiang Town, guards her mother's signature sign while managing debts. Lu Chengzhou, a down-and-out man, finishes eating noodles without money to pay and is kept by her to wash dishes to pay off the debt. With a bully forcing marriage and applying pressure, to protect her shop and marriage autonomy, she drags him to register their marriage. Lu Chengzhou is actually a group heir who pretends to be bankrupt to avoid an arranged marriage, and his whole family also falsely claims bankruptcy to move in, going from failing to tell scallions and garlic sprouts apart to truly learning to share burdens. Facing rumors, supply cuts, acquisitions, and malicious competition, Lin Xiaonuan does not rely on a wealthy background, using account books, evidence, and craftsmanship to counterattack item by item, turning the small shop into a stable catering business. After her identity is revealed, she still insists on her own rules and career, guarding the signboard.
