Su Wan, the owner of a small restaurant, faces the imminent closure of her business and, to make ends meet, enters into a one-year marriage contract with the aloof Gu Yanze. Taking on the identity of Mrs. Gu, she moves into the Gu family home to care for Grandma Gu. With her exceptional cooking, Su Wan brings warmth and life to the otherwise cold, quiet villa. A late-night bowl of comforting yangchun noodles dispels the awkwardness of their first encounter, while the stomach-friendly meals she carefully prepares every day not only soothe Gu Yanze's chronic stomach problems but also quietly melt his frozen heart. She kindly understands the housekeeper's difficulties and treats everyone in the Gu family with genuine care. Gradually, Gu Yanze shifts from cold scrutiny to secretly keeping an eye on her, quietly helping her resolve her rent troubles and falling for her without even realizing it.
