A story of love and Smile, mixed with youth and deliciousness, makes you laugh and feel moved at the same time, laugh and shed tears. Cheng Xiaoshi, the beloved daughter of Smile Pasta, is an ordinary girl who is天真直率 (innocent and straightforward), a bit reckless, a bit silly, and always faces life with a smile. Xiaoshi's favorite person is Ah Zhe, a senior student in the same school. Although Ah Zhe has never liked Xiaoshi, and even put a "curse" on Xiaoshi that "the romance will never last more than three months", Xiaoshi remains undaunted and continues to strive. She believes that one day Ah Zhe will see her sincerity and fall in love with her. Until the day she meets He Qun, Xiaoshi's long-held belief and persistence in love begin to change.
