In the hazy spring scenery, I, a person named Hu Xiaoqing, was naive and ignorant. I longed for a romantic relationship but did not dare to go beyond the strong self-control of tradition in my heart. On the last day of his freshman year, Hu Xiaoqing met Wu Manrou in an awkward manner thanks to Feng Wanjuan's attentive help. They began to mourn him for nearly a year, but Wu Manrou only treated him as a friend. Cheng Qiuqin, who met by chance, gradually fell into Hu Xiaoqing's sight. She was delighted with him, but he was obsessed with the unforgettable first time when he looked back at the innocent Wu Manrou. Roommate Awen accidentally discovered Wu Manrou embracing a boy. Hu Xiaoqing was so confused after learning the "bad news" that he stayed up all night. With the early departure of Cheng Qiuqin, Hu Xiaoqing, who had always been willing to abandon others for his pursuit, closed himself up and lonely himself. The appearance of friends Cai Shaofeng and Nie Wenqian alleviated Hu Xiaoqing's spiritual blankness and hidden unspoken pain to a certain extent. The inexplicable emotions intertwined between Cai Shaofeng and Nie Wenqian left a shadow in Hu Xiaoqing's heart that he no longer believed in love. Cai Shaofeng's departure and Nie Wenqian's disappearance once again made Hu Xiaoqing's heart shrink. Until one day, Cheng Qiuqin's phone call once again stirred up waves in Hu Xiaoqing's heart, which could not be erased for a long time. But as it was graduation season, they could only go their separate ways, no longer believing in a snow-like attachment that had no material basis. As a good friend, Shen Bingyi saw it in her eyes for four years and told Hu Xiaoqing before parting: Treat yourself well. Hu Xiaoqing returned to his hometown and saw Bai Xue again, smiling slightly as he lost himself in the pure memory and distance.
