This is a story about long-lasting secret love, jet-lagged love and urban loneliness. From 2009 to 2026, Su Wan spent sixteen years silently guarding a relationship "above AUO" - from the time they first met in college and went to Hangzhou to work together, from being inseparable to the adult world thousands of miles apart, she has always been the most tacit understanding around Zhou Shiyan
Purpose: The novel is not simply about a long secret love, but uses this "unfinished" relationship as a mirror to reflect the caution, calculation, self-protection and uncontrollable sincere desire of contemporary urban youth when facing emotions in a rapidly changing society. In the long river of time, those unspoken words and unfulfilled agreements are closely connected with our growth and ultimately form part of the "self". What the story ultimately leaves behind is a thought about how "regret" and "treasure" coexist.
