Du Yu was born in the 1980s and worked quietly in a northern city. After graduating from university, he worked in the automobile sales industry. After several years of hard work, he rose from a sales consultant to the sales director of the team. Originally, his career would be smooth and his life with friends would be infinitely beautiful. But Du Yu has always regretted that he missed the encounter with his first love Ji Xiaoqing because his father passed away when he graduated from high school.
At a high school reunion, Du Yu finally reunited with Xiao Qing, who had been searching for her for 10 years to no avail. Just when everything could clear the fog, Du Yu learned the fact that Xiaoqing was married from her conversation with her classmates. All this plunged Du Yu into infinite sadness and despair.
Later, by chance, Du Yu got in touch with Xiao Qing again, but Xiao Qing's actions based on his actions thousands of miles away made Du Yu fall into confusion and depression.
What happened to Xiaoqing in the past 10 years? Is there a childhood misunderstanding between them or is there some other unknown secret? What kind of life will Du Yu and Xiaoqing have after they meet again? Will this obsessive sadomasochism blossom again?
