A new school year has begun. After ending their pride and impetuousness in their freshman year, Qiao Chuan, Zhong Bai, Ren Yifan and others successfully entered their sophomore year. Xiao Haiyang also passed the freshman exam and did not repeat a grade as he wished. The friendship between the freshman classmates continued. After a holiday, at the beginning of the sophomore year, the departure of old classmates and the joining of new classmates caused subtle changes in their relationship. Gu Yixin went to the United States to study with his family, and Bi Shisan turned this concern into a driving force for his studies. Transfer student Xu Lianqiao transferred to the electric photography class and seemed to have a mysterious mission. The departure of the original class teacher made the originally scattered electric photography class begin to unite. The alternation of old and new characters, and the richness and heavyness of the sophomore coursework, made the story of the sophomore classmates of the 2015 electric photography class even more exciting. At this time, they have shed the immaturity of their freshman year and ushered in the fastest growth year in college. The nine people started their own dreams and realized their dreams in stumbling. Another year of college time has passed, and the friendship between the nine classmates is getting stronger and stronger.
