The city's children's tooth decay rate has soared, and pediatric dentist Lu Sisi has pointed the finger at Gu's Group's candy products. During the live broadcast, she angrily smashed Gu Zhiyuan's carefully crafted chocolate fountain, but she didn't know that the heir to the dessert group was actually an old acquaintance of hers from medical school who had conflicting ideas. The candy laboratory hidden in Gu Zhiyuan's clinic and the dental model demonstrating tooth decay in Lu Sisi's hands collided fiercely in repeated confrontations.
In the whirlpool of public opinion and business conspiracies, the two were forced to join forces. Lu Sisi discovered that there was hidden guilt and persistence behind Gu Zhiyuan's research and development of candies; and Gu Zhiyuan was gradually moved by Lu Sisi's dedication to children's oral health. Specially made sugar-free candies, late-night debugging of tooth-protection formulas, these confrontations with professional warmth quietly melted each other's defenses. When the traps of business rivals and the fetters of childhood shadows follow one after another, can these "enemies" find their own love formula on the road to protecting sweetness and health?
