Dessert chef Su Nianchu was set up by her sister to become a substitute bride for Lu Jingshen, the CEO of the Lu family, who was rumored to be a "wife-killer". The two signed a three-year contract: she would serve as a shield, and he would help her pay off the family's huge debt.
Su Nianchu originally wanted to keep a low profile, but with his exquisite dessert skills and gentle and tough character, he melted the heart of President Bingshan little by little. From being forced to live together to falling in love, from being a contractual couple to truly loving each other, the two go hand in hand amidst the undercurrents of wealthy families, business conspiracies, and the mystery of their origins.
When the contract expired and Su Nianchu wanted to leave decently, the man who once said "we will have nothing to do with each other after three years" chased him to the airport with red eyes: "The agreement is void. What I want is never three years, but a lifetime."
