Shen Yan, a technology CEO suffering from severe anorexia, was exiled to a small southern town to "wait for death." He was emaciated and disgusted with all food and heat, until he stumbled into Lin Nuan's vinegar hot pot restaurant that was about to close down. The spicy, sour and fragrant soup base is a battle for his taste buds and the beginning of redemption. From a mouthful of soup to a meal, she used intangible cultural heritage delicacies passed down for centuries to melt his frozen past bit by bit. When his business empire called again, and when her old store faced demolition, they discovered that what healed each other was never just the food itself, but the hot protection and human fireworks hidden in the three meals and four seasons. This is a two-way redemption story about "eating well" and "being loved well".
