Li Ran (played by Tong Dawei) had a relationship with a quantum mechanics teacher in the university by chance, and then this fruitless relationship left an indelible impact on him. A few years later, Li Ran, who has become a reporter of the provincial newspaper, met Zhou Meng (played by Jiang Yiyan) at a friend's party, and the two fell in love at first sight and were intoxicated by the romantic beauty of love. However, the appearance of Li Ran's ex-girlfriend Liu Yi not only brought a short-term dispute between the two, but also brought Du Xiaobin (played by Zhang Xinyi) into Li Ran's life. Li Ran originally only went to help Du Xiaobin to fulfill Liu Yi's wish, but he was gradually attracted by Du Xiaobin's stubbornness and talent. Although we continue to flirt with various sweet fragments of love, do we really know where youth should be placed?
