Meanwhile, Chen Ruohan, Wu Yantao's American friend from ten years ago, gets back in touch with him. After going through all kinds of trials, their love triangle gradually deepens. Lin Yuxin, Yu Guo'er, Hong Xucheng, and Zheng Baiqi have been friends since childhood. Along with Tang Jiaqi and Xu Cong, whom they met in high school, and Wu Yantao's upright bodyguard, Qiao Zijie, their other friends witness it all. They share tears and laughter, grow together, and eventually head off to college.
