How could life be sweet all the time? This truth was told by Zhu Yuetian's mother when she was very young. As a university professor, her mother hoped that her daughter could understand that life is bitter and sweet, first bitter and then sweet. But the optimistic father named his daughter Zhu Yuetian, hoping that she would taste the sweetness of life and not experience any pain. Zhu Yuetian, whose real name is Sheng, had a lifelong sweet tooth, so after graduating from college, he opened a beloved dessert shop named "Tian Qian Tian Hou" instead of going to work. At the city's annual dessert carnival, Zhu Yuetian met a sweet and bitter man who enriched her life - Lin Muxuan, the owner of an advertising company, and opened an interesting chapter in her life. There are also Chen Xujia, a subordinate of the advertising company who has always had a crush on Lin Muxuan, He Wei, a college classmate who has always liked Zhu Yuetian, and Zhu Yuetian's best friend Yang Shu, and together they started a life story with laughter and tears around the dessert shop. After a series of ups and downs, Zhu Yuetian and Lin Muxuan joined hands to lead a sweet life.
