Gao Xing (Xu Lu)'s father was a famous barista. After his death, he left behind a thick and precious coffee notebook. Gao Xing's biggest dream is to inherit his father's business one day. However, the family is financially tight. As the only pillar of the family, Gao Xing came to Prince Coffee Shop to apply for a job as a barista there. Gao Xing's boss is a man named Jiang Shangwu (Yang Jue). Gao Xing concealed his daughter's body. At the beginning, there was a lot of conflict between the two because of various misunderstandings. It can be said that they were tit-for-tat. But as time went by, Gao Xing's persistence in coffee touched Jiang Shangwu, and the two became close friends in both career and life. Qin Zhemo (Wang Yang) is Jiang Shangwu's cousin, and his appearance made the relationship between the few people complicated.
