Mu Yu Kong Lai is a coffee shop in Nancheng. Its owner is a 27-year-old girl named Chen Yu. Here Chen Yu meets high school student Bai Qing, and they experience their youth together; here Chen Yu reunites with her old friend Alice, and at the same time Chen Yu begins to face the emotional problems with her boyfriend Lin Zimu again. Seventeen-year-old Chen Yu's wish was to have her own coffee shop. Twenty-seven-year-old Chen Yu's wish came true. Seventeen-year-old Chen Yu has many wishes, and 27-year-old Chen Yu is the one who helps realize her wishes. Each of us was Chen Yu at the age of seventeen, with the same desire; but we were all different Chen Yu, busy with different desires at the age of twenty-seven.
