Su Wanwan, a public relations elite in Haicheng, has a double life as a Gemini - she is charming to the outside world, but she is soft and cute to the outside world. At a business reception, she accidentally collided with the cold and ascetic president of the Lu family, Lu Zhiheng. Due to the Su family's capital chain crisis, the two reached a one-year contract. Contractual cohabitation agreement; during the relationship, Lu Zhiheng was attracted by Su Wanwan's agility and fun, and unconditionally trusted and doted on her. Su Wanwan was also attracted by the contrasting cuteness in her daily life; in the face of Bai Lianhua's entanglement, Su Wanwan asserted her sovereignty domineeringly, and Lu Zhiheng always firmly protected his wife. The contract finally turned into true love, and the two entered marriage hand in hand, with a son and a daughter; from working hard overseas to returning home in fine clothes, from black hair to gray hair, they always stayed together through ups and downs. They used fifty years of love to interpret the romance of "twin fireworks, I will give you my preference, and they will be yours for the rest of my life", and wrote a sweet pet legend that is cruelty-free, warm and healing for all.
